5x+5y=-10 check this equation

x=1, y=-3

Step-by-step explanation:

5(1)=5

5=-10 -5(-3)

5=5    yes!

5(1)=5 +-30=-25

-25=-25   yes!

since both of the values are equal to each other this is the answer

careful when typing in the answer as these websites are tricky at grading. I mean make sure you follow the correct format.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
