14. Rob uses free weights at the gym every 3 days and he uses the weight machines every 5 days.
Today Rob used both free weights and the weight machines. How many days will it be before he uses
both kinds of weights on the same day again?

Answers

Answer:

15 days

Step-by-step explanation:

Since he used both of the weights today, he will only do both on the day they come together.

weights: 3 days, 6 days, 9 days, 12 days, 15 days

machine: 5 days, 10 days, 15 days

Because the numbers both were the same on 15 days, then that is when he will do both of them

x + 8.63 = 11.001

Answers

Answer:

x=2.371

Step-by-step explanation:

Subtract 8.63 from both sides

x+8.63-8.63=11.001-8.63

x=11.001-8.63

x=2.371

Cancel out the 8.63 by subtracting it from both side of the equal sign... so you will be left with x= 2.371 which will be your answer

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.5 gallons of fuel. A warning light comes on when the raining fuel is 1.5 gallons or less. write an inequality to determine the number of days diego's father can drive the car without the warning light coming on.

Answers

Answer:

0.5n < 12.5

n < 25 days

Step-by-step explanation:

Total gallons of fuel = 14 gallons

Warning light comes on when the remaining fuel is 1.5 gallons or less

Gallons of fuel used without warning light = 14 gallons - 1.5 gallons

= 12.5 gallons

Gallons of fuel used per day = 0.5 gallons

Number of days = n

inequality to determine the number of days diego's father can drive the car without the warning light coming on.

0.5n < 12.5

n < 12.5/0.5

n < 25 days
