The correct answer is 18 . if you follow pemdas it really helps.
Answer:
Step-by-step explanation:
<h3>Given</h3>
- ΔXYZ with m∠Z > m∠X + m∠Y
<h3>Options</h3>
<u>m∠X + m∠Z < 90°</u>
- incorrect, the sum of these two angles should be > 90°
<u>m∠Y > 90°</u>
- incorrect, it should be < 90°
<u>∠X and ∠Y are complementary</u>
- incorrect as angle Z is greater that the sum of angles X and Y, then sum of three angles would be greater than 180°
<u>m∠X + m∠Y < 90°</u>
- correct, this is the only possible option
5.0666666667=(6.2+5.5+3.5)/3, which would round to an average of 5 hours worked per day
Answer:

Step-by-step explanation:
We want to find the inverse of

We interchange x and y.

We need to solve for y, so let us multiply through by 2.

Subtract 6 from both sides.

Therefore the required inverse is

-20 x 2 or -10 x 4 both equal -40
-2 x 3 = 6
