Wrote and solve an equation that will help you find three consecutive even numbers that sum to 600

vladimir1956 [14]

Answer:

198, 200 and 202

Step-by-step explanation:

Represent the three consecutive even numbers by x, x + 2, x + 4.

Then:

x + x + 2 + x + 4 = 600

Combining like terms, we get:

3x = 594, so:

x = 198

x + 2 = 200

x + 4 = 202

The three consecutive even numbers are 198, 200 and 202.

You have 20 quarters and then find 40% more and then spend 75% how much money do you have left

kirza4 [7]

You have $1.75 left

Step-by-step explanation:

Given,

Number of quarters already have = 20

Percent of quarters found = 40% of already have

Number of quarters found = $\frac{40}{100}*20$

Number of quarters found = $\frac{800}{100}$

Number of quarters found = 8

New total = 20+8 = 28 quarters

Percent of quarters spent = 75%

Number of quarters spent = $\frac{75}{100}*28$

Number of quarters spent = $\frac{2100}{100}$

Number of quarters spent = 21

Quarters left = 28-21 = 7

1 quarter = 25 cents

7 quarters = 25*7 = 175 cents

$1 = 100 cents

175 cents = $\frac{175}{100}=\$1.75$

You have $1.75 left
