Answer:
<h2>x = 17</h2>
Step-by-step explanation:
3(x - 7) = 30 is our equation, since we take 7 away from the number and then multiply the result by 3.
3x - 21 = 30
Add 21
3x = 51
Divide by 3
x = 17
To check.
3(17 - 7(
3(10)
30 = 30 Correct

Answer:
Step-by-step explanation:
8)
around the tank = 12 * circumference
circumference = d
c = 30
c = 94.2477796
area around tank = 12 * 94.2477796 = 1130.973355
now top of tank
area of a circle =
* = 706.858347
add the two surface areas together for the total
706.858347 + 1130.973355 = 1837.832
total surface area = 1837.8
10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is
** 10 = 282.7
Answer:
Approximately 485 meters
Step-by-step explanation:
We can first construct a right triangle, using the 500 m length of hill as our hypotenuse. Using the fact that the cosine of an angle is the ratio of the adjacent side to the hypotenuse, we see that
where x is the horizontal distance covered. Solving for x, we find this horizontal distance to be
so our answer is approximately 485 m.
Apply distributive property
-9-9x+4=-5
Combine like terms
-5-9x=-5
Add 5 to both sides
-9x=0
Divide both sides by -9
x=0
Final answer: x=0
