Hi there!

To solve is pretty easy. First, simplify.

21/4=(1/2x+3x) -> Combine Like Terms
21/4=7/2x
FLIP
7/2x=21/4

Multiply both sides by 2/7.
(2/7)*(7/2x)=(2/7)*(21/4)
x = 2/3

Hope this helps!

Help me so confused?

BD is 31 degrees because it is the same.

ADB is 90-31 because it is a right angle ( 59 degrees)

DEC is 180 - (31*2) because the 180 is of the trangle and the 31 is the same on the other side so times 2 then removed from 180

What is the answer to 2 1/4 x 3 1/9
vlada-n [284]
2 1/4 times 3 1/9

Make the fractions into decimals

So now it’s 2.25 times 3.11...

Multiply that to get 6.99 but since the 3.11... is a repeated sequence you would round it to 7, which is your answer!

You deposit $2000 each year into an account earning 7% interest compounded annually. How much will you have in the account in 30
SVETLANKA909090 [29]

The amount that will be in the account after 30 years is $188,921.57.

<h3>How much would be in the account after 30 years?</h3>

When an amount is compounded annually, it means that once a year, the amount invested and the interest already accrued increases in value. Compound interest leads to a higher value of deposit when compared with simple interest, where only the amount deposited increases in value once a year.

The formula that can be used to determine the future value of the deposit in 30 years is : annuity factor x yearly deposit

Annuity factor = {[(1+r)^n] - 1} / r

Where:

  • r = interest rate
  • n = number of years

$2000 x [{(1.07^30) - 1} / 0.07] = $188,921.57
