Answer:
Step-by-step explanation:
8x - 2y = 6
-8x + 4y = 12
2y = 18
y = 9
8x - 18 = 6
8x = 24
x = 3
(9, 3)
Answer:
4.95 and 2.25
Step-by-step explanation:
x+y=7.2
x-y=2.7
Add equations
x+y + x-y= (2x-y+y)=2x
7.2+2.7=9.9
Therefore 2x=9.9 x=9.9/2=4.95
x=4.95
x+y=7.2
4.95+y=7.2
y=7.2-4.95=2.25
y=2.25
It will be 12y mmmmmmmmmmmmmmmdmdkdjnejddjhsjssj

Answer:


Step-by-step explanation:
As a mixed fraction, There are 3 circles with 5 pieces in each so our denominator will be 5
The number that is shaded is 2 whole circles so that is 10 and 2 out of 5 of last one.
The whole number is 2 and the fraction for the last circle is 2/5 so our mixed number is

Now to find the improper fraction turn 2 into a fraction with 5 as a denominator.

Which equal

Then add 2/5 to 10/5
