Step-by-step explanation:

<u>Step 1: Define</u>

6x + 4 = 5x + 17 + 120

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    6x + 4 = 5x + 137
  2. Isolate <em>x</em> terms:                             x + 4 = 137
  3. Isolate <em>x</em>:                                       x = 133

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    6(133) + 4 = 5(133) + 17 + 120
  2. Multiply:                               798 + 4 = 665 + 17 + 120
  3. Add:                                     802 = 682 + 120
  4. Add:                                     802 = 802

Here we see that 802 does indeed equal 802.

∴ x = 133 is the solution to the equation.

Explain in your own words how you would graph the equation y = -4x + 25
madam [21]

Answer:

See below

Step-by-step explanation:

First, I would choose three different points with some distance between. Let's do x = -5, x = 0, and x = 5. Next, I would plug those numbers into the equation, like so:

y = -4(-5) + 25 = 20 + 25 = 45

y = -4(0) = 25 = 25

y = -4(5) + 25 = -20 = 25 = 5

Next, I would plot the points [(-5, 45), (0, 25), (5, 5)] on an x-y graph. Finally, I would take a ruler, line it up with the three points, and draw a line through those three points, extending from one side of the graph to the other to show the equation is continuous.

Two friends, Lucy and Lydia, had just bought their first cars. Lydia uses 3 gallons of gas to drive 114 miles in her car. The gr
alexandr402 [8]

Answer:

3.5 miles

Step-by-step explanation:

Lydia:

3 gallons of gas = 114 miles

We want to know how many miles a friend can travel on one gallon of gas, so we divide both sides by 3

1 gallon of gas = 114/3 miles = 38 miles

Lucy:

One point is

10x corresponds to 415y

10 gallons = 415 miles

divide both sides by 10 to get one gallon on a side

1 gallon = 41.5 miles

Lydia:

38 miles = 1 gallon

Lucy:

41.5 miles = 1 gallon

For 1 gallon, the difference is 3.5 miles, with Lydia having 3.5 miles less than Lucy.

M3L7 Homework
insens350 [35]

Answer:

  • Length = 30 inches
  • Width = 10 inches

Step-by-step explanation:

Given the perimeter of a rectangle P = 80 inches

Let 'x' be the width of a rectangle.

i.e.

x = width

As the length of a rectangle is three times its width. Thus,

length = 3x

We know that perimeter is the sum of all the sides (width and length) of a rectangle. So,

The Perimeter of a rectangle = 2(width + length)

substituting P = 80, width = x, length = 3x

80 = 2(x + 3x)

80 = 2x + 6x

80 = 8x

divide both sides by 8

80/8 = 8x/8

10 = x

Thus, the value of x = 10

Therefore,

The width = x = 10 inches

The length = 3x = 3(10) = 30 inches

Thus,

  • Length = 30 inches
  • Width = 10 inches
