Answer:
5
Step-by-step explanation:
9x - 3 - 8x = 7 - x
9x - 3 - 8x + x = 7
2x - 3 = 7
2x = 10
x = 5
Answer:
t = 2 sec
Step-by-step explanation:
h = – 2t²– 6t + 20
When the rocket hits the ground. h = 0 ft.
– 2t²– 6t + 20 = 0 /: (-2)
t² + 3t - 10 = 0
(t + 5)(t - 2)=0
t = - 5, t = 2
Time can be only positive.
Considering the situation described, the measure of angle x is of 60º.
<h3>What is the measure of angle x?</h3>
Researching this problem on the internet, we have that a 180º ray is bisected into two parts, each of 90º.
- The first part has angles of 70º and y.
- The second part has angles of 60º and x.
Due to the bisection, angles 60º and x are complementary, that is, they add up to 90º, hence:
60º + x = 90º
x = 30º.
The measure of angle x is of 60º.

multiply 5.5 the width with 1.5 by 3 which gives you 24.75 inches feet long.
5.5 x 1.5 x 3=24.75 that's your answer.
