Answer:

x = 20

Step-by-step explanation:

38x+40+120x=34x-7(20-19x)\\\rule{180}{0.5}\\\text{Simplifying the left:}\\\\38x+120x+40\\\\158x + 40\\\\\text{Simplifying the right:}\\\\34x-7(20-19x)\\\\34x - 140 + 133x\\\\34x + 133x - 140\\\\167x - 140\\\rule{180}{0.5}\\158x + 40 = 167x - 140\\\\158x + 40 - 40 = 167x - 140 - 40\\\\158x = 167x - 180\\\\158x - 167x = 167x - 167x - 180\\\\-9x = -180\\\\\frac{-9x}{-180}\\\\\boxed{x = 20}

Hope this helps.

The average of six weights is 12 kilograms. Another weight of 5 kilograms is added to the scale. What is the average of the seve
Anastaziya [24]

Answer:

Hi there! Your answer here is 11kg - the average of the seven weights is 11kg. To find the average of a group of numbers, you add all of the numbers (12, 12, 12, 12, 12, 12, 5), then divide by the count of those numbers (7).

12 + 12 + 12 + 12 + 12 + 12 + 5 (or 12*6 + 5) is equal to 77.

77 / 7 = 11.

So the average of the seven weights is 11kg.

Have a great day! - Mani :)

A circle is drawn within a square as shown.
alukav5142 [94]

Answer:

168.56 in²

Step-by-step explanation:

The area will be found by subtracting the area of the circle from the area of the square.

The area of the square will be given by A = 28(28) = 784 in².

The area of the circle will be given by A = 3.14(14²) = 3.14(196) = 615.44 in².

The area of the shaded portion is given by

784-615.44 = 168.56 in²
