Phone’s plus charges a connection fee of 35 cents and 3 cents per minute. which equation could be used to determine the number of minutes, X, when a phone call would cost the same at both companies A 0.35 + 0.3 = 0.45 + 0.2x
B 0.35 + 0.3x= 0.45 + 0.02x
C 35 + 0.03 = 45 + 0.2x
D 35 + 0.03x = 45 + 0.02x

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c?

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

Four individuals pool money together to start a new business and agree to split the profits equally. n invests $6,000, x invests $2,000, y invests $8,000 and z invests $4,000. if the profits for the first month were $100,000, y receives than if the profits were divided in proportion to how much they invested.
