Step-by-step explanation:
Y is equal to:
2/3x - 2 = 10
2/3x = 10 + 2
2/3x = 12
3/3x = (12 ÷ 2) × 3
x = 18
Not sure but its worth a try.

0.5s + 1 = 7 + 4.5s Subtract 4.5s from both sides
-4s + 1 = 7 Subtract 1 from both sides
-4s = 6 Divide both sides by -4
s = -

Simplify
s = -
Answer:
9u
Step-by-step explanation:
18u³ / 9u = 2u²
45u²/9u = 5u
27u / 9u = 3
The sum of the internal angles in a simple pentagon is 540°.
105 + 135 + 92 + 87 = 419
540 - 419 = 121
The angle is 121
