Answer:r = -1

Step-by-step explanation:

8+8r-(3+3r)=0

We add all the numbers together, and all the variables

8r-(3r+3)+8=0

We get rid of parentheses

8r-3r-3+8=0

We add all the numbers together, and all the variables

5r+5=0

We move all terms containing r to the left, all other terms to the right

5r=-5

r=-5/5

r=-1

Hope this helps

Im struggling to answer this question.
blsea [12.9K]

Answer:

35/100

Step-by-step explanation:

You have 12% of horses (10÷84=0.1190 and 0.1190 = 12%)

You have 54% of sheep (54÷84=0.535 and 0.535=54%)

Subtract the amount of Sheep and Horses for the total amount of animals

84-(10+54)

You have 35% of cows (29÷84=0.345 and 0.345=35%)

35% to a fraction is 35/100 (simplified version 7/20)

I hope this helps (:

Simplify:2 1/3(4 1/4÷2)
kondor19780726 [428]

Answer:

4\frac{23}{24}

Step-by-step explanation:

We want to simplify:

2\frac{1}{3}(4\frac{1}{4}\div 2)

We convert to improper fraction to get:

\frac{7}{3}(\frac{17}{4}\div 2)

We now deal with the parenthesis by multiplying with the reciprocal of 2.

\frac{7}{3}(\frac{17}{4}\times \frac{1}{2} )

This gives:

\frac{7}{3}(\frac{17}{8})

We multiply to get:

\frac{7}{3}(\frac{17}{8})

This simplfies to:

\frac{119}{24}

We write as mixed number

4\frac{23}{24}

What is the future amount of 12,000 invested for 5 years at 14% compounded monthly?
Triss [41]

The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest.

<h3 /><h3>what is compound interest?</h3>

To begin, change R from a percentage to a decimal, using the formula:

r = R/100 r = 14/100

r = 0.14 rate per year;

Next, find A by solving

A = P(1 + r/n)nt A = 12,000.00(1 + 0.14/12)(12). (5)

A = 12,000.00(1 + 0.011666666666667)(60) (60)

A = $24,067.32

Summary: The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.

The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest. You will then be left with the loan balance plus compound interest.
