Answer:

Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:

Since we know their equations, substitute:

Solve for x. Combine like terms on the left:

Subtract 9 from both sides:

Divide both sides by 9:

So, the value of x is 9.
We want to find A. So, let's use the equation for A:

Substitute 9 for x:

Add:

So, the measure of A is 17°.
Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
17 = y + 4x....we have to get y on one side and everything else on the other side.....so the easiest way would be to subtract 4x from both sides
17 - 4x = y + 4x - 4x....combine like terms
17 - 4x = y...rearrange
y = -4x + 17 <===== slope intercept form
It’s 90 degrees hope this helps
Step-by-step explanation:
1/4(0.25)
1/2 + 1/4 = 3/4 (0.75)
Answer:450
Step-by-step explanation: If you add 150 to 150 that will give you 300.If you add 300 to 100 that will give you 400.Finally if you add 400 to 50 that will give you 450.
Your answer is: 450 students
