URGENT: DUE TONIGHT OR I GET DETENTION!!!!

Mathematics
1 answer:
suter [353]4 years ago
7 0

Answer:

63 weeks

Step-by-step explanation:

252 - 3x = 378 - 5x

       + 5x          +5x

Add 5x to both sides

252 + 2x = 378

-252         - 252

Subtract 252 from both sides

2x = 126

Divide 2 from both sides

x = 63

Check you work by plugging 63 where the x is

252 - 3(63)

252 - 189 = 63

378 - 5(63)

378- 315 = 63

$600 invested with compound interest at a rate of 4% per year for 10 years <br> formula:M= P(1+i)^n
makkiz [27]
Answer: M = 2100$

Explanation:

M = P(1 + I)^n

P = 600$, I = 4% = 0.04, n = 10

=> M = 600(1 + 0.04)^10
M = 600(1.04)^10
M = 600(3.5)
M = 2100$
