(3x^2-10x+4)+(10x^2-5x+8)
Answer:
132−15+12
Step-by-step explanation:
Answer:
13x² - 15x + 12Step-by-step explanation:
(3x^2-10x+4)+(10x^2-5x+8)
= 3x² - 10x + 4 + 10x² - 5x + 8
= 3x² + 10x² - 10x - 5x + 4 + 8
= 13x² - 15x + 12What is the difference of 85.23 and 2.675?
Answer: 82.555

Beth has $400 in the bank. She paid a start-up fee of $45 plus $3 every time she rides the bus. Write and solve an equation to determine how many times she can ride the bus.
Answer:
The equation is: y=(x-45)/3 and Beth can ride the bus 118 times.
Step-by-step explanation:
From the information provided, the total cost of riding the bus is equal to the start-up fee plus the cost of each ride for the number of times Beth rides the bus:
x=45+3y, where x is the total cost of riding the bus and y is the number of times Beth rides the bus.
Now, you can solve for y and you can replace x with 400 that is the total amount Beth has:
x=45+3y
y=(x-45)/3
y=(400-45)/3
y=355/3
y=118
According to this, the answer is that the equation is: y=(x-45)/3 and Beth can ride the bus 118 times.
PLEASE HELP IVE BEEN WORKING SO LONG ON THIS
Answer:
Part A The 4th bubble y= -55x+1630
Part B 1630
Part C 55
Step-by-step explanation:
Part A Use slope to find answer. In this example, points (1,599) and (4,1430).
Next use equation y1-y2/x1-x2. In this example, 1599-1430/1-4 which equals 169/-3 and that equals -56.3333333333333333333333. Since y= -55x+1630 is closer, choose that answer.
Part B use y intercept. The y intercept is 1630
Part C Use the slope -55. It decreases by 55.
____CO2 + ___H2O _____C6H12O6 + _____O2
Answer:
Chemical Equation Balancer C6H12O6 + O2 = CO2 + H2O. The chemical symbol for oxygen is O, but pure oxygen exists as diatomic (“two-atom”) molecules, represented by the chemical formula O2.
Step-by-step explanation:
Mario got a part time job mowing lawns. On Monday he charged his neighbor $25 to mow his lawn, then spent $6 to refill his lawn mower with gas. The next day he mowed his Grandparents yard for $20. How much money does Mario have after mowing both yards?
Answer:
$39Step-by-step explanation:
Step one:
He charged $25 and spent $6 on gas on Monday.
then he made 25-6= $19 mowing his neighbor's lawn.
the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).
So he mowed his Grandparents yard for $20.
total money saved for Monday and Tuesday is
19+20= $39
Hence he has $39 for mowing both yards

Ok, the mode is the number that appears the most in the data set.
Let's organize this chaos, first. (I hated stats in middle school and elementary.)
6,7,8,9,10,6,7,10,7,6,7,9,7,6
Its best to organize it before finding it!
6,6,6,6,7,7,7,7,7,8,9,9,10,10.
Sevens are most numerous in this data set, with 5 7's!
There's your mode.

18/13=3/4x
what does x equal?
Answer:
x = 24/13
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
18/13 = 3/4x
Step 2: Solve for x
Divide both sides by 3/4: x = 24/13Step 3: Check
Plug in x to verify it's a solution.
Substitute: 18/13 = 3/4(24/13)Multiply: 18/13 = 18/13Determine the measure of angle A. PLEASE HELP PLEASE.
a.54 DEGREES
b.1 DEGREES
c.36 DEGREES
d.32 DEGREES
First we find the value of [tex]x[/tex]. This is quite simple as it's a right angled triangle with one of the angles already given. The main concept is vertically opposite angles meaning if 2 lines intersect, the opposite 2 angles are equal.
So the angle [tex]55x - 1[/tex] is for the interior of the triangle too. Now due to angle sum postulate, [tex]36x + 55x -1 + 90 = 180[/tex]
Simplify this and you get: [tex]91x = 91[/tex]
Hence, [tex]x = 1[/tex]
Now, we need to find the value of angle [tex]A[/tex] which is [tex]36x[/tex] which is basically [tex]36 * 1[/tex] when we replace [tex]x[/tex] with [tex]1[/tex].
Henceforth, angle [tex]A[/tex] is equal to [tex]36[/tex] so option [tex]C[/tex] is correct. :D
===================================================
Explanation:
Place point B at the intersection of the lines where the 90 degree angle is located.
Place point C at the other intersection point.
So we have triangle ABC.
Since we have a right angle, this means angle B is 90 degrees.
Angle C is 55x-1 degrees because it's vertical to the angle shown. Vertical angles are congruent.
See the diagram below.
-------------
From here we use the idea that all three angles of any triangle always add to 180
A+B+C = 180
(36x) + (90) + (55x-1) = 180
91x+89 = 180
91x = 180-89
91x = 91
x = 91/91
x = 1
Use this x value to find angle A and C
A = 36x = 36*1 = 36
C = 55x-1 = 55*1-1 = 54
Finding angle C is optional since your teacher just wants angle A, but it's useful to help check our answer
A+B+C = 36+90+54 = 180
So this confirms we have the right x value.
During the big storm, 29 in. of snow fell in 8 hours. Find the rate of snowfall in inches per hour.
Answer:
3 5/8 inches of snow per hour
Step-by-step explanation:
29 divided by 8 = 3.625
(3 5/8)
if 29 inches for 8 hours, and you need to find how much snow in one hour, you can get 1 hour from 8 hours by doing 8 divided by 8. You use the same number to find the snow, divide 29 by 8 and you get the rate at which snow builds up.
Hope this wasn’t too confusing ^0^
Pls factorise x²-7x+12
Step-by-step explanation: The first thing you're going to probably
try to do here is to factor out a greatest common factor.
The problem is, there is no factor that is in common
to all three of these terms so you may think it's unfactorable.
However, this trinomial is in a special form.
We have an x squared term, an x term, and a constant term.
When a trinomial is in this form, it can be
factored as the product of two binomials.
So start by setting up two sets of parentheses.
Inside each set, we will have the two terms that compose each binomial.
So we have ( )( ).
The first term is a factor of the x² term, x · x.
For the second term, we need factors of 12 that add to -7.
Since the middle term is negative, we use the negative factors of 12.
Notice that -4 and -3 add to -7 and multiply to be 12.
So our answer is (x - 4)(x - 3).

Kellie is allowed to watch up to 90 minutes of tv pre day. If she watched 10 minutes before school, how many 20-minute tv episodes can she watch after school?
Answer:
4
Step-by-step explanation:
As she watches 90 minutes of tv pre day and she watched 10 minutes before school
So minutes left 90-10=80
And 1 episodes contains 20 minutes
So she can watch tv episodes
= 80÷20
=4 (ans)

where is the question ??
The league raised $1,560 through fundraisers. Trenton estimates the cost of buying jackets for each player in the league. He concludes that the league has raised enough money. Do you agree with Trenton? Explain.
Answer:
Step-by-step explanation:
Estimates are rough guesses based on current or previous prices. Therefore, it is impossible to conclude whether or not Trenton has actually raised enough money, especially if no actual price for the jackets has been provided. That being said an estimation is usually a close enough representation of the actual value, which would mean that the chances of having raised enough money (if that is what the estimates say) are pretty high.

Jay wants to rent a metal detector. A rental company charges a one-time rental fee of $20 plus $5 per hour to rent a metal detector. Jay has only $60 to spend. What is the maximum amount of time he can rent the metal detector?
Answer:
8 hours.
Step-by-step explanation:
If you have the 20 as the fee, you'd only have 40 dollars left. If you do 40/ 5 you'd get your answer of 8 hours.
