Answer:

x = 30.

Step-by-step explanation:

2/7 = 8/x−2

Cross multiply:

2(x - 2) = 7*8

2x - 4 = 56

2x = 60

x = 30.

I need help with number five. Thank you much!
s344n2d4d5 [400]
Hey there.

For 5:

We already have been given all the information we need to solve for this- it's just really extensive, so bare with me here.

With our initial deposit of $150 in January, we give 10% of the current value in the following month. This means 10% of 150 will be deposited into the checking account in February, and so on for the rest. I will work this out.

10% of 150 = 15; we deposit $15 into the account in February.
10% of 165 = 16.5; we deposit $16.5 into the account in March.
10% of 181.5 = 18.15; we deposit $18.15 into the account in April.
10% of 199.65 = 19.965; we deposit $19.96 in May (as we don't have an economical value worth a thousandth of a dollar in this problem).
10% of 219.61 = 21.961; we deposit $21.96 in June.
10% of 241.57 = 24.157; we deposit $24.15 in July.
10% of 265.72 = 26.572; we deposit $26.57 in August.


Our total value is $292.29, although if we added the thousandths, we'd have $292.31; therefore your answer is going to be D.) $292.31

I hope this helps!
