Answer:

A) x + 5y = -2

B) 2x -7y = 10

We multiply A) by -2

A) -2x -10y = 4 then we add B)

B) 2x -7y = 10

-17y = 14

y = -(14/17)  then plugging this into A)

A) x = -2 +-5*(-14/17)

A) x = -2 + 4.1176470588

A) x = 2.1176470588

Two angles are supplementary. The first angle is 3x degrees. The second angle is (2x+25) degrees. Determine the measure of the s
Alex17521 [72]
A = 3x
b = 2x+25
180 = a + b
180 = 3x + 2x + 25
180 = 5x + 25
155 = 5x
x = 31

a = 3*31 = 93
b = 2*31 + 25 = 87

vekshin1
The value of track is given by:
V(x)=32500(0.92)^x
when x=2
V(2)=32500(0.92)^2=$27508

when x=3
V(3)=32500(0.92)^3=$25,307.36

Difference in values will be:
27508-25307.36
=$2,200.64
