means there exists an integer
such that
. We can divide both sides by
because
. This implies
for some integer, which is identically
.
Answer:
140
Step-by-step explanation:
175% of 80 = 140
Minus 9x from both sides
-3y=-9x+12
divide both sides by -3
y=3x-4
Well since you already completed the table, a pattern would be that the left column is twice the amount of the right column ( 30x2=60, 35x2=75,etc.)
X +(x+2) + (x+4) = 5(x+2)-18
3x+6 = 5x+10-18
3x+6 = 5x-8
3x=5x-14
-2x=-14
x=7
(x+2) =9
(x+4) =11
7 + 9+ 11 =27
5(9)-18 =45-18 =27
3 numbers are 7, 9 & 11
