The sum of x and y is 7. The value of y is three more than the value of x. Write a system of equations to model this.

x= 2 , y= 5 (5+2=7)

Step-by-step explanation:

I don't really know how to put it into an equation- but here's your values?? Sorry if this didn't help ):

x+y=7

y= x+3

Step-by-step explanation:

i just took the test

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
