Answer:
Step-by-step explanation:
LCM×HCF= Product
LCM×3=180
LCM=180/3=60
It's easy it's just 50 divided by 20 so the answer is 2.5 minutes
Answer:
Joe makes 5 dollars a week
Step-by-step explanation:
Joe started with 173 so you will subtract that from the total
208-173=35
You will then divide that number by the number of weeks he has worked
35÷7=5
Therefore joe makes 5 dollars a week
Answer:
$2.20
Step-by-step explanation:
If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
Answer:

Where m is the slope and b the intercept.
Using the information given the variable cost 5.5 per hour represent the slope and the fixed cost 10 represent the value of b and then our model would be given by:

Wher y is the total cost and x the hours rented
Step-by-step explanation:
For this case we want to model the situation with a general equation given by:

Where m is the slope and b the intercept.
Using the information given the variable cost 5.5 per hour represent the slope and the fixed cost 10 represent the value of b and then our model would be given by:

Wher y is the total cost and x the hours rented
