Answer:
2) 62.5 wpm
3) 12.7 miles per gallon
4)18 commercials per hour
5) 22.9 ounces per dollar
Step-by-step explanation:
2) 500 words / 8 minutes = 62.5 words per 1 minute
3) 216 miles / 17 gallons = 12.7 miles per gallon
4) 36 commercials / 2 hours = 18 commercials per hour
5) 64 oz / $2.79 = 22.9 oz per $1
Answer:
a,b
Step-by-step explanation:
We want to know how much is the price per pound (or unit rate) of ground beef, given that we know the price for Elliot's purchase. We will see that each pound costs $4.75
So we know that (3 + 2/5) lb of ground beef costs $16.15, the cost of a single pound will be given by the quotient between the total cost and the amount purchased, then we need to solve:
We can rewrite the denominator as:
(3 + 2/5)lb = (15/5 + 2/5)lb = (17/5) lb
Replacing that we get:
So each pound of ground beef costs $4.75

Substitution method is one of the ways to solve this system.
-5x+y=4 and 4x-4y=16.
First we will divide the second equation with number 4 and get
x-y=4 => x=y+4 than we will replace x in the first equation
-5(y+4)+y=4 => -5y-20+y=4 => -4y=4+20 => -4y=24 => y=-6
x-(-6))=4 => x+6=4 => x=4-6=-2 (x,y)=(-2,-6)
Good luck!!!
