X/2 = 68.2
Given that Colin’s number is X, he divided it by 2. Hence it will be x/2 =68.2. Hope this helps! :)
D
I think it is D (-3/4x)-7(3)
The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
a. Write an equation that shows the amount of dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
The equation is y = -3/2x + 30
b. Explain the meaning of the negative slope above.
As the number of car washes increase, the dollars left on the card decreases.
c. What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2
x = 20

By definition, a parallelogram is merely a quadrilateral. Its key characteristics are having two sets of parallel sides. Consequently, it would have two sets of equal lengths, denoted as a and b. A perpendicular bisector is the red line in the picture that bisects length b into two lengths while creating a right angle. The area of a parallelogram is
A = bh, where
b is the side that meets with h
h is the perpendicular height of the parallelogram
Since h is not known, we have to solve it first through applying the pythagorean theorem.
h = √29^2 - 12^2 = 26.4 m
Thus,
A = (12 cm + 33 cm)(26.4 cm)
A = 1,188 square centimeters
