I NEED HELP ON THISSS

1) x=0.3 y=2.2

2) x=6 y=9

Step-by-step explanation:

1/5 is 20% because 100 divided by 5 is 20. So 11 and 1.5 times 0.20 will get the amount for 20% aka 1/5. So 1.5, x, times 0.20 is 0.3. 11, y, times 0.20 is 2.2. For the next problem, 1:3 means that you multiply a side on E by 3 to get that same side on D. So 3, y, times 3 is 9. To get x, you reverse it. So 18, x, divided by 3 is 6.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
