7b) A bag of fun-sized Twix bars contains 20 candy bars weighing 30 ounces. The line represents the relationship between the number of Twix bars and the total weight. The point (1, 1.5) is on the line. Write an equation that represents the proportional relationship between Twix bars and their weight. Indicate the meaning of each variable.

x=12 units bd= 10 units

step-by-step explanation:

answer: finding the extract measurements and knowing the points

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
