So the answer's 17

I hope this helps

N + d + q = 35
0.05n + 0.10d + 0.25q = 6
n = d + 5

n + d + q = 35
0.05n + 0.10d + 0.25q = 6.....multiply by -4
----------------
n + d + q = 35
-0.20n - 0.40d - q = - 24 (result of multiplying by -4)
----------------add
0.80n + 0.60d = 11

0.80(d + 5) + 0.60d = 11
0.80d + 4 + 0.60d = 11
1.40d = 11 - 4
1.40d = 7
d = 7 / 1.40
d = 5 <==== there are 5 dimes

n = d + 5
n = 5 + 5
n = 10 <==== there are 10 nickels

n + d + q = 35
10 + 5 + q = 35
15 + q = 35
q = 35 - 15
q = 20 <=== there are 20 quarters

Answer:

My as well just put random numbers and letters in it. They can't check it on edumentum. Don't bother with the tutorials. But heres the answers for all of them.

For A

Angles A, B, and C form a triangle. The sum of the angle measurements of a triangle is 180°. So, I can find the measurement of angle C by subtracting the measurements of angle A and angle B from 180°.

For B

Angle A and angle B each measure 25°. Find the measurement of angle C by subtracting the measurements of angle A and angle B from 180°. The numerical expression for the measurement of angle C is 180° – 25° – 25°.

For C

The measurement of angle C is given by the expression 180° – 25° – 25°. So, angle C measures 130°.

For  D

Angle L and angle C are supplementary angles. The sum of supplementary angles is 180°. So, I can find the measurement of angle L by subtracting the measurement of angle C from 180°.

For E

Angle C measures 130°. Find the measure of angle L by subtracting the measurement of angle C from 180°. The numerical expression for the measure of angle L is 180° – 130°.

For F

The measurement of angle L is given by the expression 180° – 130°. So, angle L measures 50°.
