A. 9 Quarters, 13 Dimes, 6 Nickels
3. Translate a(y+1)=b into a verbal sentence.
A. A times y plus one equals b
5. The volume V of a pyramid is equal to one third the product of the area of the base b and its height h.
A. V=(bh)/(1/3)

1. s=189/3
2. 28=n+d+q; d=q+4 = q=d-4; d=n+7; q=(n+7)-4 {q=n+3}
3. Add 1 to y and then multiply by a.
4. (Work for the whole summer? Per day? Per week?)
5. V=(bh)/3
6. C=2pr

1.
Mph = 189Miles / 3 Hrs 100%
2.
Q + 4 = D
N + 7 = D
Q = D - 4
N = D - 7
Q + N + D = 28
(D - 4) + (D - 7) + D = 28 100%
Q = D - 4
3.
A times Y plus A = B 100%
5.
V = (1/3) * (b * h) 100%
6.
C = 2(pie)r 100%
