6-8. Always do brackets first!
Step-by-step explanation:
30% of lightbulbs = 45 lightbulbs
100% of lightbulbs
= 45 * (100/30) = 150 lightbulbs.
Hence there are 150 lightbulbs in the batch.
m equals meters
so 3 m would be three meters
Answer:
Step-by-step explanation:
5x + 4y = 20
You need to express y in terms of x.
isolate the y term
4y = -5x + 20
divide both sides by the coefficient of y
y = (-5/4)x + 5
f(x) = (-5/4)x + 5
