Answer:
-4
Step-by-step explanation:
She put the y in the same equation ....it was the mistake
She had to put the y in the other equation:
2x+ 22 - 10x = - 2
-8x + 22 = - 2
-8x= -2 - 22
-8x= - 24
x= 3
Answer:
y=2
Step-by-step explanation:
You first square root both sides to get rid of the second power on the left side.
It would look like this..
After this, the second power is canceled out and the square root of 100 is 10. The equation should look like this.
Next, divide both sides by 5.
5y/5= y.
10/5= 2.
Answer:
95.49°
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle in radians. Here, r = 9 ft and s = 15 ft. Thus, the central angle Ф is
Ф = (15 ft) / (9 ft) = 5/3 radians, or
5 rad 180°
------- * ---------- = 95.49°
3 π rad
