Simplify the expressions by combining like terms
10r - 5r + 3r - 8r
Answer:
0
Step-by-step explanation:
Combine like terms, perform the operations with the coefficients of the variable, then write the variable.
10r - 5r + 3r - 8r
= 5r + 3r - 8r
= 8r - 8r
= 0
Answer:
0
Step-by-step explanation:
10r-5r=5r
5r+3r=8r
8r-8r=0
A health club charges a $50 initial fee plus $2 for each visit. Moselle has spent a total of $144 at the health club this year . Use an equation to find how many visits she has made
Answer:
Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y-intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.
Subtract 50 from both sides-
144-50=2x+50-50
94=2x
Divide 2 from both sides-
94/2=2/2
x=47
Moselle made 47 visits to the health club.

John reads an equal number of pages of a book every week. The graph below shows the number of pages of the book left to read, y, after x weeks:
A graph titled John’s Book Reading shows Number of Weeks on the x-axis and Number of Pages Left on the y-axis. The scale on the x-axis shows numbers from 0 to 6 at increments of 1, and the scale on the y-axis shows numbers from 0 to 175 at increments of 25. A straight line joins the ordered pairs 0, 125 and 1, 100 and 2, 75 and 3, 50 and 4, 25 and 5, 0.

Find the total area for the following composite shape.
A.48 sq m
B.36 sq m
C.84 sq m
D.64 sq m
Answer:
C. 84
Step-by-step explanation:
To make it easier to find the total area, you should break the shape into two parts, a triangle and a rectangle.
Step 1:
To find the rectangle area we now we have to multiply l * w
In this case, the length is 12 and the width is 4 so 12*4 = 48
Step 2:
To find the area of the triangle you have to do the formula A = 1/2bh where b is the base 12, and h is the height (10-4) 6. So 6*12 = 72 and 72/2 is 36
Step 3:
Last you need to add the area of both the rectangle and the triangle to get the total area of 84 sq meters

It is expected that ___times as many students at the middle school ride in a car as walk to school.
It is expected that ___% of the middle school students ride a scooter to school.
In a random sample of 45 students at the middle school, it is expected that___students ride a bus to school.
In a random sample of 360 students at the middle school, it is expected that ___ students ride a bike to school.

Answer:
2, 10%, 15, 42
Step-by-step explanation:
18 / 9 = 2
Total number of students = 60
6 / 60 = 1/10 or 10%
1/3 ride the bus, so a sample of 45 would give 15
7/60 ride a bike so multiply by 360 = 42

If a cube edge measurement is quadrupled, what would be the ratio of the surface area of the original cube verse the surface area of the larger cube?
the answer is…. volume will be 27 times
reason..
old volume ….. x^3
new volume… (3x)^3
i.e. 27* x^3
on dividing , we get the answer 27
I would appreciate brainliest!A contractor is tiling your bathroom with one-foot square tiles. How many tiles are needed for the job? PLS HELPPP
Answer:
Depends on the bathroom
Step-by-step explanation:
Basically since I don't know the bathroom length and width, Ima just cut it down for you.
It is your bathroom area (length*width) divided by the area of the tiles, which is 1*1=1 foot^2(square)
Also it depends on the unit you used for the bathroom, you gotta transfer the unit for the bathroom length and width into feet.
So you should get number for bathroom area with the unit feet square.

Solve this equation until you have the squared variable for the missing side length on one side of the equal sign and a rational number on the other.
The solution of the equation 9² + 12² = c² will be 15 and negative 15.
What is the solution to the equation?A designation of amounts to the unknown parameters that establish the equals in the formula is referred to as a result.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The equation is given below.
9² + 12² = c²
Simplify the equation, then the value of the variable c will be
c² = 81 + 144
c² = 225
c = ±√225
c = ±√(15)²
c = ± 15
Thus, the solution of the equation 9² + 12² = c² will be 15 and negative 15.
More about the solution to the equation link is given below.

5y-14=2y-2 solve for y and show work plz
Answer:
y=4
Step-by-step explanation:
Let's solve your equation step-by-step.
5y−14=2y−2
Step 1: Subtract 2y from both sides.
5y−14−2y=2y−2−2y
3y−14=−2
Step 2: Add 14 to both sides.
3y−14+14=−2+14
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
Answer:
5y + -14 = 2y + -2
-14 + 5y = 2y + -2
-14 + 5y = -2 + 2y
-14 + 5y = -2 + 2y
-14 + 5y + -2y = -2 + 2y + -2y
5y + -2y = 3y
-14 + 3y = -2 + 2y + -2y
2y + -2y = 0
-14 + 3y = -2 + 0
-14 + 3y = -2
-14 + 14 + 3y = -2 + 14
-14 + 14 = 0
0 + 3y = -2 + 14
3y = -2 + 14
-2 + 14 = 12
3y = 12
y = 4
