A
Explanation:
4.6 percent of 44.95 = 2.0677 + 44.95 = 47.0177 - round 47.02
Step-by-step explanation:
y is directly proportional to x^2.
This means that y = kx^2, where k is a real constant.
When x = 7, y = 245:
245 = k(7)^2 = 49k. By division, k = 5.
Now we know that y = 5x^2, when x = 9, y = 5(9)^2 = 5 * 81 = 405.

look at the picture ok :)
Option is B. 2
Answer:
1/2x-3=141
so first add 3 from both sides:
1/2x=141+3
1/2x=144
next divide is 1/2 on both sides
x=144/(1/2)
x=288
Answer:
20c
Step-by-step explanation:
C represent the chocolate Mason brought. Cameron brought 20 times as many chocolates. This means that however many chocolates Mason brought, Cameron has 20 times more than what Mason brought. So meaning we can this equation as
