Answer:

x+y=37-------(1)

5.5x+13.5y=355.5-----(2)

Put x=37-y in eqn 2

5.5(37-y)+13.5y=355.5

203.5-5.5y+13.5y=355.5

8y=152

y=19

x=18

Given (x – 7)2 = 36, select the values of x.
Aneli [31]
Regroup
2(x-7)=36
Divide both sides by two
X-7= 36/2
Simplify 36/2 to 18
X-7=18
Add 7 to both sides
X=18+7
Simplify 18+7 to 25
X = 25

Is 1/8 less than 1/6?
trasher [3.6K]
1/8 or 1/6 
which is greater 

1) Lets make the fraction into a percent 
1/8 ⇒ 1 ÷ 8 =  0.125 
0.125 x 100 = 12.5%

1/6 ⇒ 1 ÷ 6 = 0.16....
0.16.. x 100 = 16.6.. = 16.7%

1/8 is bigger since it is closer to 0. 

Hope this helps
