Answer:
Both are correct because after substituting the same value into both expressions, the result is the same.
Step-by-step explanation:
Given the expression:
(1/6)*(6*x + 12) - (1/2)*(4*x + 2)
Applying distributive property:
(1/6)*6*x + (1/6)*12 - (1/2)*4*x - (1/2)*2 =
= x + 2 - 2x - 1 =
= -x + 1
Then, for any number substituted into both equations, the result is the same
The total amount of people surveyed is 50 people. 50 x30%= 15 or 50 x .3 = 15
The colors that add to 15 total people is red and purple.
Height of the figure is 12 ft.
Solution:
In this image parallel sides and area are given but height is not given.
We have to find the height of the figure.
Given image is a trapezoid.
Parallel sides = 4.2 ft and 9 ft
Area = 79.2 ft²
Area of the trapezoid =
79.2 = 6.6 × h
Divide by 6.6 on both sides, we get
12 = h
Switch the sides of the equation.
h = 12
Height of the figure is 12 ft.
Y=(1/3)x + (-4)
Rise over run
By the way the 1/3 is a fraction
