Question

(08.06 LC)

Variable b is 7 more than variable c. Variable b is also 1 less than variable c. Which pair of equations best models the relationship between b and c? (1 point)
a


b = c + 7
b = c − 1
b


b = c − 7
b = c + 1
c


c = b + 7
c = b − 1
d


c = b − 7
c = b − 1

Answer 1

B:

b = c + 7

b = c - 1

Explanation:

"Variable b is 7 more than variable c" can be expressed mathematically as

b = c + 7

"Variable b is 1 less than variable c" can be expressed mathematically as

b = c - 1

So the second pair,

b = c + 7

b = c - 1

best models the relationship between b and c

Hope this Helps :)

Answer 2

First one

Explanation:

Variable b is 7 more than variable c:

b = c + 7

Variable b is also 1 less than variable c:

b = c - 1
