Answer:
Deb will have $93.17 in 3 years
Step-by-step explanation:
FV = P(1 + r)^n
FV = 70(1+0.1)^3
FV = 70(1.331)
FV = 93.17
the answer for this question is (B) 5,-2
X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1
