Look at the two equations: -3x + 6 = 21 -3x + 6 < 21 Which statement best describes the process used to solve the equations? In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality. In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality. The process is exactly the same for solving the equation and solving the inequality. The process for solving the equation is entirely different from solving the inequality.

Answer:

40 miles per hour.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] ÷ 22.5 = [tex]\frac{1}{4}[/tex] × [tex]\frac{2}{45}[/tex] = [tex]\frac{1}{90}[/tex] mile per second

[tex]\frac{1}{90}[/tex] × 3600 = 40 miles per hour.

A.

You have to convert 22.5 seconds to hours

1st you have to go from seconds -> minutes:
22.5 seconds x 1min / 60secs = 0.375mins

2nd go from minutes to hours:
0.375mins x 1hr / 60minutes = 0.00625hours

Since it is miles per hour, miles would go on top and hours (or seconds in this this case) would go on the bottom.

To find miles per hour:

(1/4) miles / 0.00625 hours = 40 miles per hour.

Therefore, hyena runs 40 miles per hour.

Find measure of angle S
A. 10
B. 34
C. 68
D. 102

Answers

Answer:

C

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

10x + 2 is an exterior angle of the triangle, thus

10x + 2 = 8 + 6x + 34 = 42 + 6x ( subtract 6x from both sides )

4x + 2 = 42 ( subtract 2 from both sides )

4x = 40 ( divide both sides by 4 )

x = 10

Thus

∠ S = 8 + 6x = 8 + 6(10) = 8 + 60 = 68° → C

Determine whether the triangles are similar. If so, name the postulate or
theorem you used.
