Question

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

Answer 1

What do you think the first one is?
"Difference between two numbers is 1"

Answer 2

its B

Answer 3

@terminallychill It's not B... And don't give out the answer.

Answer 4

its A

Answer 5

@mollyann It's not A either.

Answer 6

Answer my question.
Difference between two numbers is 1. What's the equation?

Answer 7

definitely D

Answer 8

yea its D

Answer 9

@terminallychill It's not D. Not I've given the answer.. It's C

Answer 10

\m/

Answer 11

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

Answer 12

y is the smaller number because
x - y > 0 if y < x
x - y < 0 if y > x

Answer 13

its not C

Answer 14

my test said thats wrong

Answer 15

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
