Answer:
y = 9
Step-by-step explanation:
the two sides are balancing so that means one 'x' and three 'y' equals four 'x' plus one 'y'
x + 3y = 4x + y
subtract 'x' from each side to get:
3y = 3x + y
subtract 'y' from each side to get:
2y = 3x
if 'x' = 6 then:
2y = 3(6)
2y = 18
y = 9
Given conditions are :
In 1980's, a typical middle-income household earned= $34,757
In 2009, a similar middle-income household earned= $38,550
And we have to find relative increase in income for these households from 1980 to 2009.
So first we will find the total increase in amounts.

Relative increase = 
= 10.91% or rounding it off we get approx 11%.
Hence, the answer is 11%.
Answer:
the top one
Step-by-step explanation:
the only y one with negative 2
60 is 83% of 72.
60 divided by 12 is 5, and 72 divided by 12 is six.
5/6 equals 0.83
0.83 x 100 is 83, or 83%.
