Answer:

100 degrees

Step-by-step explanation:

You can get the measure of b by knowing that a straight line is 180 degrees. So the interior angle formed at R is 40 degrees. That makes the angle at p 40 degrees. The interior sum of a triangle is 180 degrees.

So 40+40+angle at a = 180

angle at a = 180-80 = 100 degrees.

Answer:

A.) 2x - 9x - 30 = -6

Step-by-step explanation:

hello !

to solve this system of equations, first, we substitute the equation y = 3x + 10 to the <em>y </em>variable in the equation 2x-3y = -6. Therefore, we get:

2x - 3(3x+10)=-6

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

2x - 9x - 30 = -6

First, multiply 25 with 24

600 + 9 = 690

Note that there are 60 minutes in 1 hour. Divide 7 minutes with 60

7/60 = ~0.12 (rounded)

~690.12 hours is your answer
