Answers

Answer:

6

Step-by-step explanation:

Step one: make 2 2/3 into an improper fraction

2 x 3 = 6

Add 6 to the numerator

gives you 8/3

Step two: divide

16=48/3

(48/3) / (8/3)

48 divided by 8 = 6

Answer:

6

Step-by-step explanation:

Turn 2 2/3 into an improper fraction  8/3

Turn 16 into a fraction  16/1

16/1 divided by 8/3 means flip the second fraction

16/1 * 3/8

Multiply and reduce

48/8 = 6

A tortoise moves at a speed of 26 inches in 9 seconds. What is its average speed in feet per hour?
≈ 780 ft/h
≈ 867 ft/h

26 in=2.17ft
9 sec = 0.0025 hr
2.17/0.0025 = 867

Douglas went to Charlies General Store to get gas. He paid $52.20 for 20 gallons of gas. How much would he have paid if he got 25 gallons instead

Answers

Answer:

65.25

Step-by-step explanation:

52.20 is the total for 20 gallons of gas

for 25 gallons --> 2.61 x 25 = 65.25

answer: $65.25

$52.20 divided by 20 equals $2.61 per gallon if you multiply that by 25 gallons you will end up with $65.25

Distributive property

Step-by-step explanation:

8y + 4

We can factor out a 4 out of both as both are divisible by 4

8y / 4 = 2y

4 / 4 = 1

So 8y + 4 is the same as saying 4 * 2y + 4 * 1

This can be written as 4(2y + 1) which is written using the distributive property
