Answer:
18
Step-by-step explanation:
4x + 5x = 180
10x = 180
x = 18
X is the number, therefore;
x+50% of x=210
50%=50/100=0.5
We can suggest this equation:
x+0.5x=210
1.5x=210
x=210/1.5
x=140
Asnwer: the number would be 140.
Answer:
r(-2) = -5 , r(0) = -7 , r(5) = -12
Step-by-step explanation:
Plug in the numbers for x and then solve. : )
r(-2) = - (-2) - 7
r(-2) = 2 -7
r(-2) = -5
r(0)= -0 -7
r(0)=0-7
r(0) = -7
r(5) = -5 - 7
r(5) = -12
<span>An oblong box has a volume equal to lwh, where l is the length, w is the width, and h is the height. If the volume is 24 cubic feet, solve for the height in terms of the other sides.
Given:
volume of 24 cubic feet
Required:
height
Solution:
V = 24 cubic feet
assume that the length, weight and height of the box are all equal
so l = w = h
24 = l^3
l = 2.88 feet</span>
