gof) = 12x+8
Step-by-step explanation:
to find gof plug f into g :

then simplify:
( g o f) = 12x+8
Answer:
x + y ≥ 45
Step-by-step explanation:
This is because the total amount of minutes could be equal to 45, meaning your inequality sign has to have a line underneath it.
Additionally, x + y is greater than or equal to because the amount could be more than 45... therefore, 45 is not greater than x + y
The equation to this question would be: 3x+5=12
x = Nora's saved quarters we dont know full answer yet
2x + 6 = quarters Chris saved
5(x-3)= five times the difference of quarters and 3noras .
Now put equations together to solve.
2x + 6 = 5(x - 3)
Remove parentheses
2x + 6 = 5x - 15
Subtract 5x to both sides and solve x.
-3x + 6 = -15
Now subtract 6 both sides and solve
-3x = -21
x = 7 = Nora quarters
Chris original problem and substitute for x .
2x + 6 =
2 (7) + 6 =
14 + 6 = 20 quarters
So Nora has 7 quarters and Chris 20
Answer:
1 1/2 bags
Step-by-step explanation:
given 1/8 of a bag will fill up 1/12 of a garden box, i.e.
1/8 bag ------> fills 1/12 box (rearrange this)
1/12 box ----> requires 1/8 bag
to find how many bags it takes to fill 1 box, we simply multiply both sides of this equation by 12 to get the unit rate of fill
( 1/12 ) x 12 box -----> requires (1/8) x 12 bags
1 box ------> requires 12/8 = 3/2 = 1 1/2 bags (answer)
