Answer:
Step-by-step explanation:
The equation given represents the number of movies, , that must be rented to spend the same amount at each store.
We want to find the number of movies, so we should solve for . To solve for we must isolate it on one side of the equation.
First, let's get all the terms with a variable on one side. Subtract 1.5r from both sides of the equation.
0.75 and are being multiplied. The inverse of multiplication is division. Divide both sides of the equation by 0.75
20 movies must be rented to spend the same amount at each store.
Answer:
169
Step-by-step explanation:
5²= 25

Answer:
All of them are multiples of 1.
Step-by-step explanation:
Even though 12, 34, 45, and 56 are composite, 1 and 23 are prime.
Answer:
y = 6x+1 . . . . . y ≠ 0
Step-by-step explanation:
Multiplying by y gives the linear equation ...
(1+y)/2 -(3x +1) = 0
1 +y = 2(3x +1) . . . . . add (3x+1), multiply by 2
y = 6x +1 . . . . . . . . . . eliminate parentheses, subtract 1
There are an infinite number of (x, y) pairs that will satisfy this equation. The above equation gives the required relation between the x and y values. The equation is undefined for y=0, so that is not a solution.
