Answer:

x = 11

Step-by-step explanation:

12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50  \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11

and check:

12(11) - 5 = 8(11) - (11) + 50 \\ 132 - 5 = 77 + 50 \\ 127 = 127

Answer:

B

Step-by-step explanation:

Consider the right triangle with hypotenuse of 60 yards and the height 12 being the side opposite the angle of incline, say x°, then

sinx° = \frac{opposite}{hypotenuse} = \frac{12}{60}, thus

x = sin^{-1} (\frac{12}{60} ) ≈ 11.54°

The solution to 4p + 2 < 2p + 5)​
Georgia [21]

After solving 4p + 2 < 2p + 5 we get p

Step-by-step explanation:

We need to solve

4p + 2 < 2p + 5

Solving

4p + 2 < 2p + 5

Subtract 2 from both sides:

4p + 2-2 < 2p + 5-2\\4p

Subtract 2p from both sides

4p

Divide both sides by 2p

\frac{2p}{2}

So, after solving 4p + 2 < 2p + 5 we get p
