13 = 2f + 5 i don't know how to solve this

1 answer:

8 0

<span>Simplifying 13 = 2f + 5
Reorder the terms: 13 = 5 + 2f
Solving 13 = 5 + 2f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-2f' to each side of the equation. 13 + -2f = 5 + 2f + -2f
Combine like terms: 2f + -2f = 0 13 + -2f = 5 + 0 13 + -2f = 5
Add '-13' to each side of the equation. 13 + -13 + -2f = 5 + -13
Combine like terms: 13 + -13 = 0 0 + -2f = 5 + -13 -2f = 5 + -13
Combine like terms: 5 + -13 = -8 -2f = -8
Divide each side by '-2'. f = 4
Simplifying f = 4

SO, f = 4

13 = 2 </span>× 4 + 5<span>

Hope I helped:P</span>

Your parents have a credit card with a balance of $3,287.90 at an interest rate of 14.5% APR. They pay $1,200.00 each month on t

It will take them approximately 3 months to pay off the balance on the credit card

<h3 /><h3>First Month</h3>

To solve this problem, we need to find the interest on 3287.90 at 14.5%

for the first month, we would have

$\frac{x}{3287.90}=\frac{14.5}{100} \\x=476.74$

Now we divide this by 12 to give the interest payable on the first month

$\frac{476.75}{12}=39.73$

So we have

$(3287.90+39.73)-1200=2127.63$

<h3>Second Month</h3>

We would do the same thing for the second month and it will give us

$(\frac{x}{2127.63}=\frac{14.5}{100})/12\\\frac{308.506}{12}=25.71$

For the second month, we have $25.71 as the interest payable

We can calculate how much would be left after the second month.

$(2127.63+25.71)-1200=953.34$

<h3 /><h3>Third Month</h3>

In the third month, since the balance remaining is less than the monthly payment schedule, we can assume they'd pay everything off which is 953.34.

From the calculations above, we can see that it'll take them 3 months to pay off the credit card balance.

The balance at the end of each month are;
