Answer:
A. The initial value is 100; it represents money left over from last year's fundraiser
Step-by-step explanation:
Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2

Answer:
Step-by-step explanation:
For any prism or cylinder for that matter, you can find the volume by multiplying the area of the base times the height. So this problem just becomes simple algebra.
B * h = V
25 * h = 80
h = 80/25
h = 3.2
If you don't get why it's the area of the base let me know and I can try to explain it.
