Answer:
x = 8
Step-by-step explanation:
3(x−5) = 9 (by PEDMAS, distribute 3 into parentheses by distributive property)
x(3)−5(3) = 9
3x - 15 = 9 (add 15 to both sides)
3x = 9 + 15
3x = 24 (divide both sides by 3)
x = 24/3
x = 8
Answer:
x = 8
Step-by-step explanation:
a² + b² = c²
x² + 6² = 10²
x² + 36 = 100
x² = 100 - 36
x² = 64

x = 8
Answer:
594 rpm
Step-by-step explanation:
Two gears will have the same linear speed, so:
v₁ = v₂
ω₁ r₁ = ω₂ r₂
(316 rpm) (79) = ω (42)
ω ≈ 594 rpm
