Answer:
<h3>x = 5</h3>
Step-by-step explanation:
The sum of two complementary angle is 90 degrees. Given the following complementary angles;
<1 = 6x + 5
<2 = 8x + 15
<1 + <2 = 90 (complementary angles)
6x + 5 + 8x + 15 = 90
14x + 20 = 90
14x = 90-20
14x = 70
x = 70/14
x = 5
Hence the measure of x is 5

6,000-5,944=
because 6,000 is how much she paid, but she only owed 5,944 so the the difference is what her refund is.
Answer:
37.7 mi²/h
Step-by-step explanation:
The area formula is ...
A = πr²
Differentiating with respect to time gives ...
dA/dt = 2πr·dr/dt
Filling in the given values, we have ...
dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h
The area is increasing at the rate of about 37.7 mi² per hour.
Answer:
Step-by-step explanation:
9x - 1 / 2 + 9/2 x = 0.128886 (43)
2 / 5x - 1b = 4/3 - 1 - 1 = 2x (4)
= x1 + 24 - 3/4 + 8
9/3 - 1 x = /3
