Answer:
Step-by-step explanation:
Assuming that for each option, you play the same number of games,x
Let y represent the cost of playing x games using option A
Option A is to buy a membership card and pay $2 every time you go to the gym. The membership card costs $20. It means that
y = 20 + 2x
Let z represent the cost of playing x games using option B
Option B is to pay $4 each time you go. It means that
z = 4x
To determine how many games will be played before cost of option A equal to the cost of option B, we would equate y to z. It becomes
20 + 2x = 4x
4x - 2x = 20
2x = 20
x = 20/2 = 10
It will take 10 games for both to be the same
<u>Answer:</u>

<u>Step-by-step explanation:</u>
We are given the following equation and we are supposed to solve y in terms of x. It simpler terms, it means that we have to make y the subject of the equation while x being used in it as it is:

Taking the constant 4 to the side where x is to get:

Multiplying the denominator 3 to the other side of the equation to get:

Isolating y to make it the subject:

First you need to convert 45 degress to radians,then you use the arc length formula which is = thr radius * the angle to get the answer
40s+2bs+200=number of books needed
if we want 12 books and 8 stalls
b=12
s=8
solve
40(8)+2(12)(8)+200=
320+192+200=
712
needs 712 books
