Answer:
8 scoops of flour
Step-by-step explanation:
Set up a proportion so,
(5/25)=(x/40) *Solve for X*
25x = 200
x = 8
Answer:
Part A: Profit = 400 + 70 s, Part B : $3900
Step-by-step explanation:
Part A:
We know that the expression is: 0.2 ( 2000 + 350 s ). Using the distributive property :
Profit = 0.2 · 2000 + 0.2 · 350 s = 400 + 70 s
Part B :
The company's yearly profit when: s = 50 ( the total number of students )
P ( 50 ) = 400 + 70 · 50 = 400 + 3500 = $3900
Answer:
3) C
Step-by-step explanation:
The question is asking which pair is equal. Work through each problem to solve.
8(2r) and 10r
16r ≠ 10r
6r + 3 and 9r
6r + 3 ≠ 9r
9(3r - 4) and 27r - 36
27r - 36 = 27r - 36
r + r + r + r + r and r⁵
5r ≠ r⁵

-5(s + -30) = -10
Reorder the terms:
-5(-30 + s) = -10
(-30 * -5 + s * -5) = -10
(150 + -5s) = -10
Solving
150 + -5s = -10
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-150' to each side of the equation.
150 + -150 + -5s = -10 + -150
Combine like terms: 150 + -150 = 0
0 + -5s = -10 + -150
-5s = -10 + -150
Combine like terms: -10 + -150 = -160
-5s = -160
Divide each side by '-5'.
s = 32
Simplifying
s = 32</span>
