Answer:
-33
Step-by-step explanation:
this math equation looks relatively simple so i assume the actual equation is -2/3x - 8 = 14
add 8
-2/3x =22
multiply by -3/2
answer is -33
10.222=10 and 222/1000
I'm not sure if that's what you were looking for but I hope this helps!

Answer:
Angle 2 = 27 and Angle 1 = 135
Step-by-step explanation:
Let x = angle 2
Let 5x = angle 1
5x+x=162
6x=162
x=27
Angle 1 = 5(27)
Angle 1 = 135
Answer:
slant length = 35 cm
Step-by-step explanation:
A right cone has the vertex directly above the center of the base . The surface area of the right cone can be represented below.
surface area = πr(r + l)
where
r = radius
l = slant height/length
surface area = πr(r + l)
r = 10/2 = 5 cm
surface area = 628 cm²
Therefore,
628 = π × 5(5 + l)
628 = 5π(5 + l)
628 = 25π + 5πl
628 = 25 × 3.14 + 5 × 3.14 × l
628 = 78.5 + 15.7l
628 - 78.5 = 15.7l
549.5 = 15.7l
divide both sides by 15.7
l = 549.5/15.7
l = 35 cm
slant length = 35 cm
