I'm confused with this, please help me. thanks ​

Answer:  17%

Step-by-step explanation:

I think they're saying your expenses for everything this month were $500, and of that $500 you spent $85 on clothing.

Let's represent the percentage spent on clothing as "\star". Then

$\star \% = \frac{85}{500}$

$\frac{\star}{100} = \frac{85}{500}$

which means

$\star = \frac{85}{500} \times 100 = 17$

(If you don't understand how I moved the 100, just think about it for a bit.)

So the answer is \boxed{17\%}.

X+2y=5 and 4x-12y=-20 substitution and elimination method
Anuta_ua [19.1K]

By solving the equations x+2y=5, 4x-12y=-20 through elimination or substitution method we will get the value of x=1 and y=2.

Given two equations x+2y=5 and 4x-12y=-20.

We are required to solve the equations through elimination and substitution method.

Firstly we will solve the equations through elimination method.

x+2y=5-------------1

4x-12y=-20--------2

Multiply the equation 1 by 4 and then subtract the equation 2 from equation 1.

4x+8y-4x+12y=20+20

20y=40

y=2

Use the value of y in 1

x=5-2*2

x=5-4

x=1

From substitution method.

First find the value of x from first equation in terms of y.

x=5-2y-----4

Now put this value in second equation to get the value of y.

4(5-2y)-12y=-20

20-8y-12y=-20

20-20y=-20

-20y=-40

y=2

Put the value of y in equation 4.

x=5-2y

x=5-2*2

x=5-4

x=1

Hence by solving the equations x+2y=5, 4x-12y=-20 through elimination or substitution method we will get the value of x=1 and y=2.
