.08x+.05(15000-x)=930
.08x+750-.05=930
.08x-.05x=930-750
.03x=180
X=180/.03=6,000 at 8%
(15000-6000)=9000 at 5%

Which is the simplified form of the expression 3(7/5x+4) - 2(3/2 - 5/4x)?

Kruka [31]

Answer:

B. $\frac{67}{10} x + 9$

Step-by-step explanation:

Simplify the expression. Remember to go by the order of operations, or PEMDAS.

1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.

$3(\frac{7}{5} x + 4) -2 (\frac{3}{2} -\frac{5}{4} x)$

$\frac{21}{5}x + 12 - \frac{6}{2} + \frac{10}{4} x$

$\frac{21}{5} x + 12 - 3 + \frac{10}{4} x$

2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.

$\frac{21}{5} x + 9 + \frac{10}{4}x \\\frac{84}{20}x + \frac{50}{20}x + 9 \\\frac{134}{20}x + 9 \\\frac{67}{10}x + 9$

Thus, the answer is $\frac{67}{10} x + 9$ .

A credit card has a balance of $2,150.00 with an annual percentage rate of 22.9%. How much interest is charged in a one-month bi

Sever21 [200]

Answer: $3.42

Step-by-step explanation:

Interest= Principal x Rate x Time

From the question, Principal =$2,150

Rate= 22.9% annually means per year, to calculate the monthly rate, we divide by 12

=22.9%/12 = 1.908% per month

Time = one month, meaning one month out of 12months = 1/12

I is therefore: 2150 x 1.908% x 1/12

= 2150 × 0.01908 x 0.0833

=$3.42

I hope this is clear, please mark as brainliest answer.
