Translate the problem situation to a system of equations. Do not solve. The difference between two numbers is 1. Three times the smaller number plus the larger number is 29. What are the numbers? A. x - y = 1; x + 3z = 29 B. x - y = 1; 3x + y = 29 C. x - y = 1; x + 3y = 29 D. x + y = 1; x + 3y = 29
What do you think the first one is? "Difference between two numbers is 1"
@terminallychill It's not B... And don't give out the answer.
@mollyann It's not A either.
Answer my question. Difference between two numbers is 1. What's the equation?
@terminallychill It's not D. Not I've given the answer.. It's C
Difference between two number is 1: x-y=1... The smaller number is y. 3 times the smaller number + the larger number is 29.: x+3y=29
y is the smaller number because x - y > 0 if y < x x - y < 0 if y > x
my test said thats wrong
Show me your test... there's only two variables. x and y. from that you know A is wrong as it includes a z. It wants a difference between two numbers, so it's x-y. This rules out D as x+y is not a difference. 3 times the SMALLER number. this is in C as y is LESS THAN x for the difference x-y=1
