Answer:

(0,5/3)

Step-by-step explanation:

3y+2x=-x+5

3y=-x-2x+5

3y=-3x+5

y=-x+5/3

if x=0 then y=-0+5/3=5/3

(x, y) =(0,5/3)

harmaine spent a total of $20 at the grocery store. Of this amount, $9 she spent on fruit. What percentage of the total did she

zheka24 [161]

Answer:

45%

Step-by-step explanation:

First, let's set up a fraction of how much money she spent for fruit out of the total amount of money she spent.

$\frac{9}{20}$

For a percentage, we need a fraction out of 100. To do this, we can multiply the fraction by 5/5 (5*20=100). Notice we can only do this since 5/5 is equivalent to 1, so you are technically multiplying the fraction by 1.

$\frac{9}{20}*\frac{5}{5}=\frac{45}{100}$

A percentage is just the numerator of a number over 100 therefore it is equal to...

45%
