Answer:
A,B,C,D
Step-by-step explanation:
Mark the unknown number as x
Now the long side is x-3 inches
S=long side*short side=(x-3)*2=2x-6 square inches
S < 12 so
2x-6 < 12
2x < 12+6
2x<18
x<9
2<4<6<8<9
Answer:B
Step-by-step explanation: 113,000 - 71,500 = 41,500
The constant of proportionality is k = y/x.....k = 40/200 = 1/5
y = mx + b
slope(m) = 1/5
(200,40)...x = 200 and y = 40
now we sub...we r looking for b, the y int
40 = 1/5(200) + b
40 = 40 + b
40 - 40 = b
0 = b
so ur equation is : y = 1/5x
if pop star earned 800
800 = 1/5x
800 * 5 = x
4000 = x
