Answer:BThe mean and the range both describe how the data varies.
Step-by-step explanation:
because you are sapose to do your work by your self and i dont eaven nkow ifits right so ;b
we know that
In the <u>isosceles trapezoid</u> of the figure, the angles on either side of the bases are the same size/measure (congruent), and adjacent angles (next to each other) along the sides are supplementary.
so
m∠A=m∠B=3x
m∠D=m∠C=9x
m∠A+m∠D=
Substitute
therefore
<u>the answer is</u>
the value of x is equal to
Y=16x
The b is 0 so no need to put it in the equation.
The slope is 16/1 which is 16
8/(2x -2) = 14/(3x)
Cross multiply
24x = 28x - 28
Simplify. Isolate the x
24x (-28x) = 28x (-28x) - 28
24x - 28x = -28
-4x = -28
-4x/-4 = -28/-4
x = 6
-----------------------------------------------------------------------------------------------------------------
(x-10)/5 = 39/15
Cross multiply
15(x - 10) = 39(5)
Simplify
15x - 150 = 195
Isolate the x
15x - 150 (+150) = 195 (+150)
15x = 345
15x/15 = 345/15
x = 23
-----------------------------------------------------------------------------------------------------------------
(x + 4)/6 = (2x + 4)/9
Multiply 6 to both sides & 9 to both sides
9(x + 4) = 6(2x + 4)
Distribute 9 to x and 4, and 6 to 2x and 4
9x + 36 = 12x + 24
Isolate the x.
9x (-12x) + 36 (-36) = 12x (-12x) + 24 (-36)
9x - 12x = 24 - 36
-3x = -12
Isolate the x. divide -3 from both sides
-3x/-3 = -12/-3
x = -12/-3
x = 4
