The answer is 28. My answer is correct. 7, 14& 21 can't be the LCM son the answer should be 28.
Answer:
56m cubed
Step-by-step explanation:
7m×2m×4m=56m
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
Plug into calculator...
solve(2(-y+1)-3y=-30,y)
y=6.4
