Mrs. Solar is remodeling a house and is looking for a contractor to do the work. She is getting quotes from 3 different contractors, and will hire one of them based on the total cost. Each company uses a formula to calculate its fees based on the number of hours the work will take. Score (5 points) 1. Mrs. Solar modeled Contractor 1’s fee formula with the equation y = 50x + 200. (a) Graph the equation y = 50x + 200. Give each axis a label. (b) Describe what the equation y = 50x + 200 means in the real-world context. (c) Give 3 ordered pairs that are true to the equation and explain what each ordered pair means in the real-world context.
Answers
#b. The equation y = 50x + 200 represents the total cost that the contractor will charge for x hours of work. #c. (1, 250); (2, 300); (3, 350)
Davia draws a shape with 5 sides tow sides are each 5 inches long.tow other sides are each 4 inches long.the perimeter of the shapes is 27 inches. What is the length of the fifth side?
Answers
Perimeter = the sum of all sides Because we know that 2 sides are 5 inches and that 2 other sides are 4 inches long, we can subtract this number from the total 27 to get the 5th side. 5+5+4+4 = 18 27-18= 9 The fifth side = 9 inches

A spinner is divided into many sections of equal size. Some sections are red, some are blue and the remaining are green. The probability of the arrow landing on a section colored red is 9/20. The probability of the arrow landing on a section colored blue is 6/20. What is the probability of the arrow landing on a green-colored section? A. 15/20 B. 11/20 C. 6/20 D. 5/20
Answers
It’s D. 9/20 + 6/20 = 15/20, which is the probability of getting green and red combined. Since you want to find the probability of landing on the green section, you subtract 15/20 from 20/20 to get 5/20
The product of 5 and a number x is ¼A.5x=¼ B.x= 1/20 C.x=5/4 D.x/5=1/4 E.x+5=1/4 F.x=-19/4

I hope this helps you
5.x=1/4
x=1/20
answer is B
to find the answer you need to set up the equation 5x = 1/4 then divide each side if the equal sign by 5 so can single out x. it would be 5x dived by 5 and 1/4 divided by 5 which is x = 1/20
