Answer:

x=3 or x=13

Step-by-step explanation:

So, you would use your math skills.

8 minus what is 5.

8-3=5.

But because of the absolute value bars, you can so 8-13 which is -5 but converts to 5.

Hope this helped!

Mario is setting up a new tent during a camping trip . The tent came with 7 feet of rope . The instructions are to use 34.5 inch

Answer:

The number of $8\frac{1}{4}$ inch sections of a rope Mario can cut from the rope is 6.

Step-by-step explanation:

Given:

Mario is setting up a new tent during a camping trip . The tent came with 7 feet of rope . The instructions are to use 34.5 inches of the rope to a tie the tent stakes in the ground . Mario will use all of the rope as instructed

Now, to write and solve equation to determine the number of 8 1/4 inch sections of a rope Mario can cut from the rope.

Let the number of sections be $x.$

The length of rope Mario can cut from the rope = $8\frac{1}{4} =\frac{33}{4} \ inch.$

Total length of rope = 7 feet.

So, 1 feet = 12 inches.

Thus, the length of rope in inches = 7 × 12 = 84 inches.

The length of rope to tie the tent stakes in the ground = 34.5 inches.

According to question:

Now, to get the number of sections we put an equation:

$x\frac{33}{4} =(84-34.5)$

$x\times \frac{33}{4} =49.5$

$x\times 8.25=49.5$

Dividing both sides by 8.25 we get:

$x=\frac{49.5}{8.25}$

$x=6.$

The number of sections = 6.

Therefore, the number of $8\frac{1}{4}$ inch sections of a rope Mario can cut from the rope is 6.

Equality Properties

Step-by-step explanation:

Step 1: Define equation

a + 6a - 14 = 3a + 6a

Step 2: Solve for a

Combine like terms: 7a - 14 = 9a
Subtract 7a on both sides: -14 = 2a
Divide 2 on both sides: -7 = a
Rewrite: a = -7

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Substitute in a: -7 + 6(-7) - 14 = 3(-7) + 6(-7)
Multiply: -7 - 42 - 14 = -21 - 42
Subtract: -49 - 14 = -63
Subtract: -63 = -63

Here we see that -63 is equal to -63.

∴ a = -7 is a solution of the equation.

Step 4: Define equation

-12 - 4x = 8x + 4(1 - 7x)

Step 5: Solve for x

Distribute 4: -12 - 4x = 8x + 4 - 28x
Combine like terms: -12 - 4x = -20x + 4
Add 20x on both sides: -12 + 16x = 4
Add 12 on both sides: 16x = 16
Divide 16 on both sides: x = 1

Step 6: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -12 - 4(1) = 8(1) + 4(1 - 7(1))
Multiply: -12 - 4 = 8 + 4(1 - 7)
Subtract: -16 = 8 + 4(-6)
Multiply: -16 = 8 - 24
Subtract: -16 = -16

Here we see that -16 does indeed equal -16.

∴ x = 1 is a solution of the equation.
