Answer:
y= -2x +3
Step-by-step explanation:
This is because the slope is 2 using rise over run and the y-intercept is 3 because it meets at that point, (0,3) on the number line.
7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21
10x-40=50
Add 40 to both sides
10x=90
X=9
4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20

Answer:
The answer is 7 . First you would make the mixed fraction an improper fraction so , 3 1/2 would turn into 7/2. Them you would put 2 over 1 so you can multiply it to 7/2, so it would be 2/1 x 7/2 . So, 2 x 7 = 14 and 1 x 2 = 2 so it would be 14/2 , and to simplify you would divide 14 into 2 and it would be 7 because 7 x 2=14 . So, the answer is 7 .
