Isolate the variable by dividing each side by factors that don't contain the variable.

a= -1

4(3-6a)=36

Distribute

12-24a=36

Subtract 12

-24a=24

Divide -24 by both sides

Volume of a rectangular prism=[tex]\frac{1}{2}[/tex]b x l x h

Set up you equation

120=[tex]\frac{1}{2}[/tex](4 x 12 x [tex]x[/tex])

Multiply inside the parentheses

120=[tex]\frac{1}{2}[/tex](48x)

Multiply by [tex]\frac{1}{2}[/tex]

120=24x

Divide by 24 on both sides

5=x

Check you answer

Volume of a rectangular prism=[tex]\frac{1}{2}[/tex]b x l x h

Set up your equation

[tex]\frac{1}{2}[/tex](12 x 5 x 4)

Multiply inside the parentheses

[tex]\frac{1}{2}[/tex](240)

Multiply by [tex]\frac{1}{2}[/tex]

What is the percent decrease?

Enter your answer in the box.

%

Answers

Answer:

60%

Step-by-step explanation:

There is a 60% decrease because 60% of 2.5 = 1.5

So, 2.5 - 1.5 = 1.

1.5/2.5 = 0.60 (which is 60% as a percentage)

Miles bought a new pair of baseball cleats for $64.95. The sales tax is 6.5%. What is the total cost that Miles will pay?

Answers

Answer: $69.17175

Step-by-step explanation:

The cleats are $64.95. Tax is a percentage taken off certain goods so

6.5% of $64.95 which can be also restructured as 6.5/100 times $64.95 which is $4.22175. Tax is added onto the final cost so he shall pay $64.95 plus $4.22175. (I think)

Hi

Can you share a strategy for error analysis? Of multiplying.

Answers

Yes ! Because it’s that because it’s it

Not sure if this is right, but your teacher could give you a multiplication problem and she solves it. The twist: She makes an error within the work she did to solve it & therefore got the wrong answer. It’s now your turn to figure out where the error was and how to fix it to get the correct answer.

what is 7/12 x 3 as a fraction in simplest form

Answers

Answer:

7/4

Step-by-step explanation:

use cross multiplication and you are going to end up dividing 12 by 3 to get four as your denominator

The solution to the product of the fractions is 7/4

How to evaluate the product of the fractions

From the question, we have the following parameters that can be used in our computation:

7/12 * 3

Express 3 as 3/1

So, we have

7/12 * 3 = 7/12 * 3/1

Evaluate the products of 7 and 3

So, we have

7/12 * 3 = 21/12

Divide 21 and 12 by 3

7/12 * 3 = 7/4

Hence, the solution is 7/4

Tyshawna and Jean both work at a sneaker store and make a fifthteen dollar commission for every sneaker sold. However, Jean makes a flat rate of 75 dollars a day because he has been working at the store longer than Tyshawna. Tyshawna makes a flat rate of 65 dollars a day.
(a. Will Tyshawn and Jean ever make the same amount of money in a day? Why or why not?

Answers

Answer:

Since Jean makes a higher flat rate than Tyshawna, they won't make the same amount in a day. Jean makes a flat rate of 75 dollars a day, while Tyshawna makes a flat rate of 65 dollars a day. Tyshawna is only a few flat rates behind. Although it would seem like they could make the same amount, they wouldn't be able to. If they both had the same flat rate, they would be making the same amount almost everyday.

I hope I helped :)

Answer:

yes, because the total pay is based on how many shoes are sold and not how long one has been there so if Tyshawna sells more shoes her or his pay rate will rise.
