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

Step-by-step explanation:

26 inches = 2.17 feet

9 seconds = 0.15 of a minute = 0.0025 of an hour

2.17 / 0.0025 = 867

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

The family likes peaches and other fruits. The local farmer’s market is selling fresh peaches at a discounted price. If the farmer’s market sold 35% of its produce and has 280 peaches remaining, how many peaches did it originally have on hand? Show all your work and explain how you used equivalent ratios to solve the problem. (2 points)

Answers

Answer:

Sorry for the super late answer but here:

Step-by-step explanation:

If it sold 35% and now there is 280 remaining, that means that they produce 280 x 135%. That is also equal to 280 x 1.35. The equation is equal to 378 remaining. Please give me brainiest if you see this. However, it is ok if not since this is a super late answer plus I didn't use equivalent ratios.

Answer:

4 * 2y + 4 * 1

4(2y + 1)

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
