Question

The owner of a bike shop sells unicycles and bicycles and keeps inventory by counting seats and wheels. One day, she counts 20 seats and 28 wheels. Which equation in slope-intercept form shows that the number of bicycles (x) plus the number of unicycles (y) is 20?

A. y = -x - 20
B. y = x - 20
C. y = x + 20
D. y = -x + 20

Answer 1

use the same method you used to answer the other question

Answer 2

x+y=20
x+2y=28

Answer 3

would it be C?

Answer 4

hold on

Answer 5

i think so because the other question was asking for the wheels but this is not specifying soo

Answer 6

because if we work x+y=20 backwards we get 20-x=y

Answer 7

which will give -x+20=y
makes sense to you?
