The local store sells small pieces of candy for $0.15 each. Shondra spent $18.00 on this candy for her class party. The equation below can be used to
determine how many pieces of candy, c, that Shondra bought.
0.15 c = 18.00
How many pieces of candy did Shondra buy for the class party?

120 pieces of candy

Step-by-step explanation:

To find c, you need to divide your know values, 18.00 and .15. So 18/.15 = 120.

Shondra bought 120 pieces of candy.

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.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
