Evaluating expressions – evaluate each expression using the values given: 6q +m – m; use m=8 and q=3

18

Step-by-step explanation:

6q+m-m   subsitute the variables

6(3) + 8 - 8   cancel out 8-8 bc now its 0

6(3)  multiply

18 is the answer

18

Step-by-step explanation: take 6 times q(3) which gives you 18, then you add 8 and subtract 8

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
