Answer: 0 - 4
Step-by-step explanation:
0 - 4 = -4
-3 + 4 = 1
1 - 5 = -4
2x+5y=21, x+y=3
y=3-x
2x+5y=21
2x+5(3-x) =21
2x+15-5x=21
2x-5x+15=21
-3x+15=21
-3x=21-15
-x=6/3
-x=2
x=-2
Answer: The height of the tree is 27f
t
Step-by-step explanation: We can set up a proportion comparing the height of each object to the length of the shadow.
h/s
h/15=18/10
Cross multiply
10.h= 18*15
10h=270
Use the multiplicative Inverse

answer:
32
Step-by-step explanation:
FV = PV / (1 +r)^n
Where FV = Future Value, PV = Present Value, r = inflation rate in %,
n = number of years.
PV = $38, r = 4%, n = 3 years.
FV = 38 / (1 + 4%)^3
= 38 / (1 + 0.04)^3
= 38 / (1.04)^3 = 33.782
Hence the value 3 years from now = $33.78
