The sum of integers x and y is 280. if x is divided by 7, the quotient is y. what is the value of x?

x = 245

Step-by-step explanation:

The sum of integers x and y is 280; x + y = 280

If x is divided by 7, the quotient is y; x/7 = y so x = 7y

Now you have 2 equations:

x + y = 280

x = 7y

Substitute x = 7y into x + y = 280

7y  + y = 280

8y = 280

y  = 35

x = 7(35)

x = 245

Answer

x = 245

Step-by-step explanation:

x + y = 280

x/7 = y                      Multiply both sides by 7

x/7 * 7 = 7*y

So x = 7y

Put 7y into the top equation.

7y + y = 280

8y = 280                   Divide both sides by 8

8y/8 = 280/8            

y = 35

x + y = 280

x + 35 = 280

x + 35 - 35 = 280 - 35

x = 245

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
