The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent th larger
number and y represent the smaller number Which equations represent this situation?
2 answers:
The sum of two numbers is zero.
x + y = 0
y = -x
<span>Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
</span>Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5
The answer is the first choice.
-10 + 10 = 0
x+y = 0 y =(0-x)
3x-2y =10
3x-2(0-x)=10
3x-0 -2x=10
x=10
y=0-10 y = -10

Lets break this down step by step.
4+4+4+4=16 lawns a week.
16+16+16+16=64 lawns a month.
64+64+64+64=256 lawns a year.
Then we take 256 x $25 to get $6,400 last year.
