Answer:
60
Step-by-step explanation:
7x+30+9x+42=104
16x+72=104
16x=104-72
16x=32
x=2
SO:
<BOC=9x+42=
9(2)+42=
18+42=
60
For left put 2 on each
On the box over 100 put 82, and put 82 in the box on the right
63/170= 37%
You can divide 63/170 and you get 0.37 as decimal form but when trying to find the percent you always multiply by 100 to get a decimal to a percent and then u found your answer
Answer:
y=5x+42
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-(-3))/(-7-(-9))
m=(7+3)/(-7+9)
m=10/2
m=5
y-y1=m(x-x1)
y-(-3)=5(x-(-9))
y+3=5(x+9)
y=5x+45-3
y=5x+42
