a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!

Answers

Answer:

A = (1/2)Pa = Pa/2

 

You can multiply both sides by 2 to eliminate the fraction on the right side:

 

2A = 2(Pa/2) = Pa

 

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

 

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

 

Rewriting:

 

P = 2A/a

 

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.

0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.

Answers

Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

What is Percentage?

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

                                                       = j + 0.08j

                                                       = 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

90 degrees
65 degrees
23 degrees
155 degrees

Answers

Answer:

To find an angles supplement we can subtract the measure of the given angle ( 25 )  from 180

180 - 25 = 155

Tony’s Equation: T = M + 0.0075M

Anuyia’s Equation: T = M(1 + 0.0075M)
