Answer:
1 1/8
Step-by-step explanation:
x + 1 3/4 = 2 7/8 ( subtract 1 3/4 to isolate x)
2 7/8 is the same as 23/8
1 3/4 is the same as 7/4
you have to have the same denominator to subtract the fractions so you multiply 7/4 by 2
this gets 23/8 - 14/8 ( you subtract 23-14)
you get 9/8 which is the same as 1 1/8
When distributing the negative three into the parentheses, that canceled out the -5 and made it a positive 15
5r + 8 < 63
5r < 63 - 8
5r < 55
r < 55
{r | r < 11}
The equation to find the volume of a cylinder is
(pi)(r^2)(H)
we have the volume and radius
78.5 = (3.14)(2.5^2)(H)
78.5 = 3.14 * 6.25 * H
78.5 = 19.625H
/19.625 /19.625
4=H
The height of the cylinder is 4 meters
The answer to this question is d
