Answer:

1. 2 eggs 2. 53 mph 3. $8 per hour 4. 1 \frac{3}{4} gal per hour

Step-by-step explanation:

1. There are 4 eggs used in 2 batches. For one batch, you divide 4 eggs by 2 batches to get 2 eggs for each batch.

2. There are 265 miles in total, so to get the average speed each hour, you divide the total by 5 hours to get 53 miles per hour.

3. In 7 hours, he got $56. Divide 56 by 7 to get the pay each hour, which would be $8 per hour.

4. In a half hour, the swimming pool has leaked a certain amount of water. Double that to get how many gallons per hour. \frac{7}{8} * 2= 1 \frac{3}{4} gallons per hour.

In one month, the median home price in the West fell from $203,400 to $192,300. Find the percent decrease.
nasty-shy [4]

Answer:

94.5%

Step-by-step explanation:

Percent decrease can be represented as

[original price] * percentage = [new price]

When trying to find the percentage, you can manipulate the equation by dividing both sides by the original price to get:

percentage = [new price] / [original price]

In this case, this is represented by 192300/203400, or 94.5%

I'm confused. Help. Find x please.
miss Akunina [59]

Answer:

x = 2 and x = 10

Step-by-step explanation:

(x+3)^2 = (x - 5)^2 + (x + 2)^2

x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4

x^2 + 6x + 9 =2x^2 - 6x + 29

x^2 - 12x + 20 = 0

(x - 10)(x - 2) = 0

x - 10 = 0; x = 10

x - 2 = 0; x = 2
