If the average of x, y, and z is 32 and the average of y and z is 27, what is the average of x and 2x?

1 answer:

6 0

X + y + z = 32 * 3
27 + 27 + x = 96
X = 54
2x = 108
Average of x and 2x = (54+108) / 2 = 164 / 2 = 82
Average of X and 2X = 82

I need to find the equation of the line

deff fn [24]

Answer:

y = 3x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = $\frac{3-0}{0-(-1)}$ = $\frac{3}{0+1}$ = $\frac{3}{1}$ = 3

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 3x + 3 ← equation of line

Autumn bought 4 pairs of jeans for her kids and one shirt for herself. The shirt cost $16.99. She spent a total of $108.95. What

klio [65]

Answer:

Each Jean cost $22.99

Step-by-step explanation:

First you would subtract the cost of the shirt from the total.

108.95-16.99=91.96

Then you would divide the 91.96 by 4 to get the cost for each Jean.

91.96/4=22.99

j=$22.99
