It will take 83 1/3 tiles to fill the wall.
Let x be the entire wall:
3/5x = 50
Divide both sides by 3/5:
x = 50 ÷ 3/5
x = 50/1 ÷ 3/5
x = 50/1 × 5/3
x = 250/3 = 83 1/3
Answer: A)
Step-by-step explanation: If You just look at the numbers you can single out which one is correct
Remember that when you find 30% of the number you have to subtract the 30% from your original $90 because it is 30% off the original price.
Answer:
false
Step-by-step explanation:
if you simplify you get 5x+4=5x-10, which is false
Paralell has same slope
y=mx+b
m=slope
y=5x-1
when is the slope 5?
take the derivitive of 2e^x
f'(2e^x)=2f'(e^x)=2e^x
that is the slope
5=2e^x
divide both sides by 2
2.5=e^x
take the ln of both sides
ln2.5=x
when x=ln2.5 they are paralell
