Which expression has a value of 31?
A) 3125 + 7-5
B) (3:25) +7-5
C) 3125+ (7-5)
D) 3(125 + 7) - 5
Answer:
d. Is the answer from this question
Step-by-step explanation:
3(5+7)-5
3*12-5
36-5
31
The expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
An expression that has a value of 31
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
A) 3√25 + 7-5
= 3(5) + 7 - 5
= 15 + 7 - 5
= 17
B) (3√25) +7-5
= (3x5) +7-5
= 15 +7-5
= 17
C) 3√25+ (7-5)
= 3x5 +2
= 17
D) 3(√25 + 7) - 5
= 3(5+7) - 5
= 36 - 5
= 31
Thus, the expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

(5,7) (8,13) find the distance between each pair of point . round to the nearest tenth
Answer:
The distance would be 6.7 or 3✓5
Step-by-step explanation:
Im sure there's a faster way to find this, but I'm in 8th grade sooo yeah.
First things first we can use the equation
d=✓(X2-X1)*2+(Y2-Y1)*2
X2= 8
X1= 5
Y2= 13
Y1= 7
From here, you plug in the values and do as followed. You subtract the values to get the answer. For example 8-5 would get us (3)*2.
From here you square the 3 to get 9. You also do the same to the right side of the equation.
Now you have d=✓(3)*2 + (6)*2
From here you square it and you get d=✓9+36
Now we have: d✓45
Now we square the 45 to get 6.7082..., but we round the answer to get 6.7!
Hope this helps! If you have any questions please feel free to ask, as I understand the struggle of math! :)
Answer:
the distance would be 6.7

Find (f•g)(x).
f(x) = x^2 + 4x
g(x) = 6x
Write your answer as a polynomial in simplest form.
Answer:
6x^3 + 24x^2
Step-by-step explanation:
We need to find (f * g)(x)
If we distribute the "x" here, we should get f(x) * g(x), which is what we have to solve for
f(x) * g(x) = 6x(x^2 + 4x)
= 6x^3 + 6x(4x)
= 6x^3 + 24x^2
This is the simplest expression you can get

JK is formed by J(-12, 3) and K(8,-5). If
line r is the perpendicular bisector of JK, write
an equation for r in slope-intercept form??
Given:
JK is formed by J(-12, 3) and K(8,-5).
Line r is the perpendicular bisector of JK.
To find:
The equation of line r is slope intercept form.
Solution:
Line r is the perpendicular bisector of JK. So, it passes through the midpoint of J and K.
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-12+8}{2},\dfrac{3+(-5)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{-2}{2}\right)[/tex]
[tex]Midpoint=\left(-2,-1\right)[/tex]
Slope of JK is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-5-3}{8-(-12)}[/tex]
[tex]m=\dfrac{-8}{20}[/tex]
[tex]m=\dfrac{-2}{5}[/tex]
Product of slopes of two perpendicular lines is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{2}{5}\times m_2=-1[/tex]
[tex]m_2=\dfrac{5}{2}[/tex]
The slope of perpendicular line r is [tex]\dfrac{5}{2}[/tex] and it passes through (-2,-1). So, the equation of perpendicular line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(-1)=\dfrac{5}{2}(x-(-2))[/tex]
[tex]y+1=\dfrac{5}{2}(x+2)[/tex]
[tex]y+1=\dfrac{5}{2}x+5[/tex]
[tex]y=\dfrac{5}{2}x+5-1[/tex]
[tex]y=\dfrac{5}{2}x+4[/tex]
Therefore, the equation of line r is [tex]y=\dfrac{5}{2}x+4[/tex].
The required equation of line "r" in slope-intercept form is y = 5/2x + 15
First, we need to find the equation of a line in slope-intercept form as
y = mx + b
m is the slope of the line
b is the y-intercept
Given the coordinate points J(-12, 3) and K(8,-5)
Get the slope of the line
Slope = -5-3/8+12
Slope = -8/20
Slope - -2/5
Slope of the line "r" perpendicular is 5/2
Get the y-intercept of line r
Substitute (8, -5) and m = 5/2 into y = mx + b
-5 = -5/2(8) + b
-5 = -20 + b
b = 15
Hence the required equation of line "r" in slope-intercept form is y = 5/2x + 15

Find the distance between (3,4) and (4,-6).
Answer:
The answer is
[tex] \sqrt{101} [/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are

A bucket of water is 1/2 full but it still has 3 4/6 gallons of water in it how much water do you need to fill the bucket
Answer:
7 1/3 gallons
Step-by-step explanation:
If the bucket is half full and still has half to go, you double the current contents of the bucket. 3 4/6 times 2 is equal to 7 2/6 gallons which simplifies to 7 1/3 gallons.
I don't fully understand your question though, if the question is asking how much MORE water is needed to fill the bucket, it's 3 2/3 gallons. If it's asking how much water in TOTAL it would take to fill the bucket completely, it's 7 1/3 gallons.

Answer:
18=2x+7, The internship pays $5.50 an hour.
Step-by-step explanation:
The box on the far left is the amount the student is paid at their job, which is $18 an hour in this case. Solve 18-7 to get 11, then divide 11 by 2 to get the pay for the internship. To check your work, plug 5.50 into the equation.
18=2(5.50)+7
18=11+7
18=18
Answer:
The equation would be:
18 = 2x + 7
The internship pays $5.5 an hour
Step-by-step explanation:
18 - 7 = 2x
(Since we moved the 7 to the other side, in order to combine like terms)
11 = 2x
(Divide both sides by 2)
5.5 = x
(x = 5.5)
x would be the pay the internship pays an hour.

Answer:
Bro it's right they are wrong unless you are not giving all the information unless what they wanted you to do is do 12 + 10 as the answer
Step-by-step explanation:
Write each phrase or sentence as an algebraic expression or equation
6 more than y
3 times a number
5 less than the product of 10 and c
14 more than 6 times t
The sum of x and y is 18
A number minus 12 is y
6 more than y :
y + 63 times a number:
x ← a number
3x5 less than the product of 10 and c :
10c ← the product of 10 and c
10c - 514 more than 6 times t :
6t ← six times t
6t + 14The sum of x and y is 18:
x+y ← the sum of x and y
x + y = 18A number minus 12 is y:
x - a number
x - 12 = yy + 1 3 + 7 y − 7 = 2 ( 4 y + 3 ) solve it and whats the number of solutions
