Question

Variable a is 4 more than variable b. Variable a is also 1 less than b. Which of the following pairs of equations best models the relationship between a and b?

a = b + 4
a = b − 1

a = 4b
a = b + 1

b = a + 4
b = a − 1

b = 4a
b = a + 1

Answer 1

I am 100% sure it isn't B

Answer 2

a is 4 more then b....
a = b + 4
u understand this one ?

Answer 3

I think so is it basically asking that when we solve for a we add 4 mor to a and that gives us the answer to B?

Answer 4

i think
a=b+4 means
a is greater than b
right?

Answer 5

wouldn't it be C?

Answer 6

why u rsearching for result only

Answer 7

?

Answer 8

a = 1 less then b...how would u set this one up...any thoughts ?

Answer 9

1 - b = a

Answer 10

close...a = b - 1

Answer 11

o yeah I knew that

Answer 12

ok so now I think it's A or C but most likely A

Answer 13

so u have ur 2 equations...u know the answer ?

Answer 14

yay it's A

Answer 15

it is A

Answer 16

thx
