Answer:

3x + y = 15

Step-by-step explanation:

y/3 + x = 5

You can first move the x and y variable around so it fits the standard linear equation format.

x + y/3 = 5

In order to make it look more like the standard format, you can multiply both sides of the equation by 3 to get rid of the 3 in the denominator of the y variable.  It would look like this:

3 ( x +y/3) = 3 ( 5 )

When you multiply this out, you get this:

3x + y = 15

If a trench is 102’-6” long by 5’-4” wide and 3’-3” deep, what is the volume of the soil that was removed per cubic feet?
zzz [600]

Considering that the trench is modeled by a rectangular prism, the volume that was removed is 1776 cubic feet.

The volume of a <u>rectangular prism of length l, width w and height h</u> is given by:

V = lwh

In this problem, we want the measures in feet, and considering that 1 feet is 12 inches:

  • The length is of 102' 6''(102 feet and 6 inches), hence l = 102.5.
  • The width is of 5' 4'', hence w = 5.33.
  • The depth(height) is of 3' 3'', hence h = 3.25.

Then:

V = lwh = 102.5(5.33)(3.25) = 1776

The volume that was removed is 1776 cubic feet.

What are the solutions to the system of equations?<br><br><br> (_____ , 2) and ( _____ , _____ )
alexandr1967 [171]

Answer:

  (1, 2) and (-1, -2)

Step-by-step explanation:

Since y = 2x, the first blank tells you

  2x = 2

  x = 1

____

Since the variables are squared, a negative solution is as good as a positive solution, so x = -1 and y = -2 will also work.

Dmitry [639]
Given:
Grocery store: 8 ounces of blueberries = $2.80
Farmer's market : 14 ounces of blueberries = $4.20
1 pound = 16 ounces.

Unit rate: per ounce
Grocery store:      $2.80 ÷ 8 oz = $0.35 per ounce
Farmer's market: $4.20 ÷ 14 oz  = $0.30 per ounce

Unit rate per pound
Grocery store:      $0.35 per ounce * 16 ounces = $5.60 per pound
Farmer's market: $0.30 per ounce * 16 ounces = $4.80 per pound
