Answer:

$6725

Step-by-step explanation:

Given data

Princiapal= $5000

Rate=2.3%

Time= 15years

The function that will model this situation is given as

A=P(1+rt)

The above function is a simple interest function

Substitute our data we can find the amount A

A=5000(1+0.023*15)

A= 5000(1+0.345)

A=5000(1.345)

A=5000*1.345

A=$6725

Hence the value of the investment after 15 years is $6725

Hello! I need the answer to the question showed in the picture below
RUDIKE [14]

Answer:Answer:

−78+−12=−138

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(-7/8, -1/2) = 8

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(−78×11)+(−12×44)=?

Complete the multiplication and the equation becomes

−78+−48=?

The two fractions now have like denominators so you can add the numerators.

Then:

−7+−48=−118

This fraction cannot be reduced.

The fraction

−118

is the same as

−11÷8

Convert to a mixed number using

long division for -11 ÷ 8 = -1R3, so

−118=−138

Therefore:

−78+−12=−138

Solution by Formulas

Apply the fractions formula for addition, to

−78+−12

and solve

(−7×2)+(−1×8)8×2

=−14+−816

=−2216

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(22,16) = 2

−22÷216÷2=−118

Convert to a mixed number using

long division for -11 ÷ 8 = -1R3, so

−118=−138

Therefore:

−78+−12=−138
