Answer:
8 hours
Step-by-step explanation:
Let x = the hours she work
Equation-
1. 20x + 12 = 172
2. - 12 - 12
20x = 160
3. /20 /20
4. x= 8 hours
1. Write out the equation
2. subtract 12 from both sides
3. Divide 20 on both sides
4. Your answer is 8 hours
Answer:
No Solution
Step-by-step explanation:
If xy = 1, and y is 0, then you can plug in 0 for y. x(0) = 1. You would then need to divide by 0 on both sides, but you cannot do that. Therefore, there is no soultion.
Answer:
Step-by-step explanation:
A supplementary angle is equal to 180 degrees. So subtract 96.7 degrees from 180. 180-96.7= 83.3 degrees

The <span>Pythagorean Theorem tells us that

where c is the </span><span>hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:

We can then substitute known values, and solve:
