Step-by-step explanation:
I'll send a screenshot of the problem. I really look forward to an answer!
Answer:
a. 65
b. D
Step-by-step explanation:
The question asks for an expression that solves for the profit that the company will make from each phone. The expression would be 65x, where 65 represents $65 profit from each phone, since $50 is spent and $115 is made, 115-50 gives you the profit, $65
D is the answer because the question asks for the expression that shows the earnings, or how much is made from each phone
no solution for 6x-3x+4-2x
Answer:
4+x
Step-by-step explanation:
you combine your like terms so you take 6x-3x and you end up with 3x than you take that 3x and subtract the 2x from it so you are left with just x so that would be 4+x

Question 1:
Why should you not play this game with Roland? Use probability to prove that
the game is unfair and Roland is likely to win. SHOW ALL YOUR WORK!
Answer:
see below
Step-by-step explanation:
There are 36 possible outcomes when rolling 2 die
P( number) = number of times the sum appears / total outcomes
p(1) =0/36
P(2) = 1/36
p(3) = 2/36
p(4) = 3/36
p(5) = 4/36
p(6) = 5/36
p(7) = 6/36
p(8) = 5/36
p(9) = 4/36
p(10) = 3/36
p(11) = 2/36
p(12) = 1/36
Since he picked first he has the greatest odds so he is most likely to win
Find the volume of prism
Pls!! Show how you got the volume
Answer:
The original or the Bigger prism's volume would be 15 x 6 x 10= 900 cubic centimetres given that the smaller prism has not been cut out.
the volume of the cut-out cube would be 6 x 4 x 6= 144 cubic centimetres
so the original volume of the prism is 900 - 144= 756 cubic centimetres

Answer:
x = 32
Step-by-step explanation:
Three angles have been shown in the figure which are located at a point of a straight line.
By the property of angles on a straight line,
Sum of the angles shown = 180°
(3x - 20)° + 30°+ (2x + 10)° = 180°
(3x + 2x) + ( -20 + 30 + 10) = 180
5x + 20 = 180
5x = 180 - 20
5x = 160
x = [tex]\frac{160}{5}[/tex]
x = 32
Therefore, x = 32 will be the answer.
Answer:
[tex]x = 32 \: \: degrees[/tex]
Step-by-step explanation:
Angels in a straight line =180°
[tex]3x - 20 + 30 + 2x + 10 = 180 \\ 5x + 20 = 180 \\ 5 x = 180 - 20 \\ 5x = 160 \\ \frac{5x}{5} = \frac{160}{5} \\ x = 32[/tex]

a factor of 30 is chosen at random, what is the probability that the number has 2 digits?
Answer:
3/8
Step-by-step explanation:
Let's first start by figuring out all the factors of 30.
They are as follows: 1, 2, 3, 5, 6, 10, 15, 30
30 has 8 factors in total.
3 of the factors have 2 digits.
Probability is number of desired outcomes/number of total outcomes.
We have 3 desired outcomes and 8 total outcomes.
Therefore, the probability that the factor chosen at random will have 2 digits is 3/8.

Wang Xiu Ying is gift wrapping boxes in the shape of a cube for her class fundraiser. She calculates that the surface area, S SS, in square feet, of a cube-shaped box with a side of m mm feet is given by the function S ( m ) = 6 m 2 S(m)=6m 2 S, left parenthesis, m, right parenthesis, equals, 6, m, squared. She also finds that the cost, C CC, in dollars, of wrapping a box with a surface area of x xx square feet is given by the function C ( x ) = 0.15 x + 0.25 C(x)=0.15x+0.25C, left parenthesis, x, right parenthesis, equals, 0, point, 15, x, plus, 0, point, 25. Find an explicit expression that models the costs of wrapping a cube shaped box with a side length of m mm feet.
Answer:
[tex]C(m)=0.9m^2+0.25[/tex]
Step-by-step explanation:
The surface area of a cube-shaped box with a side of m feet is given by the function:
[tex]S(m)=6m^2[/tex]
The cost, C, in dollars, of wrapping a box with a surface area of x square feet is given by the function:
[tex]C ( x ) = 0.15 x + 0.25[/tex]
We want to find an explicit expression that models the costs of wrapping a cube-shaped box with a side length of m feet.
In the cost function, C(x), x is the surface area, therefore:
[tex]S(m)=x;$ and$\\C ( S(m) ) = 0.15(6m^2) + 0.25\\C(m)=0.9m^2+0.25[/tex]
To find the cost of wrapping a cube of side length m feet, we use the explicit function:
[tex]C(m)=0.9m^2+0.25[/tex]

Answer:
Problem 2) : the gradient is "-2", and the y-intercept is "3"
Problem 3)
A is [tex]y=2x+2[/tex]
B is [tex]y=x+2[/tex]
Step-by-step explanation:
Problem 2)
In the line given by the equation: [tex]y=-2x+3[/tex]
the "gradient" (also known as "slope") is the numerical coefficient that multiplies the variable "x". So in this case the gradient is "-2"
the y-intercept is the numerical term "+3" because that is the y-value result of evaluating the expression for x = 0
[tex]y=-2x+3\\y=-2\,(0)+3\\y=3[/tex]
Problem 3)
Consider the two lines :
[tex]y=x+2[/tex] and [tex]y=2x+2[/tex]
notice that both have the same y-intercept (that is the numerical term "2" at the end of both expressions. That means that both lines cross the y-axis at the point y=2.
Now notice that the gradient of one of them is "1" (for [tex]y=x+2[/tex] ) that is the coefficient that multiplies the variable "x". While for the other line ( [tex]y=2x+2[/tex]) the gradient is "2" and therefore steeper than the previous one.
Then, the line identified as "A" which is the one with steeper gradient, corresponds to the equation [tex]y=2x+2[/tex], and the line identified with "B" is the one with smaller gradient [tex]y=x+2[/tex] .

A piece of timber is x cm long. 7 cm is cut off. How much is left?
Answer:
x-7>0
Straight answer: x-7
Step-by-step explanation:
Assuming that the timber is X cm long and 7cm was cut off, there remaining amount is x - 7cm. In order for 7cm to be cut off, the timber must have been > 7cm long => x > 7 => x - 7 > 0
Find the gradient of the line segment between the points (0,2) and (2,-8).
Answer:
slope = - 5
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (2, - 8)
m = [tex]\frac{-8-2}{2-0}[/tex] = [tex]\frac{-10}{2}[/tex] = - 5
The value of the gradient is -1/5.
How to find the gradient of a line?In order to find the gradient of a line either of the two ways can be used. First, the equation of line should be written in terms of y, then the coefficient of x is the gradient.
The other method is to find the two points on the graph and then take the ratio of the difference of corresponding coordinates.
The given points are (0,2) and (2,-8).
Since the gradient of the line segment between points (x₁, y₁) and (x₂, y₂) is given as,
Gradient = (y₂-y₁)/(x₂-x₁)
Substitute the corresponding values to obtain,
Gradient = (2-0)/(-8-2)
= -2/10
= -1/5
Hence, the gradient of the line segment joining the points (0,2) and (2,-8) is -1/5.

Using the segment addition postulate, find the value of x.
HI = 6x + 8
IJ = 2x - 4
HJ = 124
A) 15
B) 16
C) 9
HINT THAT I WAS GIVEN: The segment addition postulate states that the lengths of the pieces of a segment will add up to the length of the entire segment.
Answer:
A. 15
Step-by-step explanation:
HI and IJ are both segments in the line HJ so HI and IJ combined equal the total length of HJ. This means we can write an equation using HI and IJ and setting them equal to HJ.
6x + 8 + 2x - 4 = 124
next step is to combine like terms:
8x + 4 = 124
then, subtract 4 from both sides.
8x + 4 = 124
-4 -4
8x = 120
finally, divide both sides by 8.
8x/8 = 120/8
x = 15
since it is equal to x, 15 is your solution!
The sum of the digits of a two-digit number is 14. If the number formed by reversing the digits is less than the original number by 18. Find the original numbers.
Answer: Dear friend my answer for this question is 86.
Step-by-step explanation:Let the two digits of two digit number be, 10s digit x and 1s digit y.
x + y = 14
x = 14 - y…..Eq..1
The nuber formed is 10x + y
If the number formed by reversing the digits is 18 less than the original number, what is the original number
On reversing the digit the number will be 10y + x
10y + x + 18 = (10x + y)
10y + x = 10x + y - 18
10y - y + x - 10x = - 18
9y - 9x = -18…Eq..2
Now substituting the value of x from Eq..1 to Eq..2
9y - 9 (14 - y) = - 18
9y - 126 + 9y = - 18
18y = 126 - 18
18y = 108
y = 108/18
y = 6
Thus 1s digit if the number is 6
Substituting the derived value of y in Eq..1 to derive value of x.
x = 14 - y
x = 14 - 6
x = 8
The 10s digit if two digit number is 8.
The original number formed is 86.
On reversing the digits, the number transform to 68, which is 18 less than original number
Answer the original number is 86.
