To answer this we will find the unit rate by dividing. Lets do it:-
10.43 ÷ 7 = 1.49
1 pound of grapes = $1.49
CHECK OUR WORK:-
1.49 × 7 = 10.43
we were RIGHT!!!
Now lets multiply to see how much 3 pounds would cost.
1.49 × 3 = 4.47
CHECK OUR WORK:-
4.47 ÷ 3 = 1.49
We were RIGHT!!
So, 3 pounds of grapes cost $4.47.
Hope i helped ya!!

Answer:
3. -5
Step-by-step explanation:
4(8-x)+36=102-6x
Expand by using distributive property
32 - 4x + 36 = 102 - 6x
Combine like terms
-4x + 68 = 102 - 6x
Add 6x to both sides
2x + 68 = 102
Subtract 68 from both sides
2x = 34
Divide both sides by 2
x = 17
Answer
x = 17
Step-by-step explanation:
g(t) = (t + 1)² − 20.25
0 = (t + 1)² − 20.25
20.25 = (t + 1)²
±4.5 = t + 1
t = -1 ± 4.5
t = -5.5 or 3.5
The zeros are (-5.5, 0) and (3.5, 0).
