♡ The Explanation/Step-By-Step ♡      

・3 (x + 4) = x - 8 - 2x

3 (x + 4) = x - 2x - 8

3 (x + 4) = -x - 8

3 (x + 4): 3x + 12

Apply the distributive law! : a(b + c) = ab + ac

a = 3, b = x, c = 4

= 3x + 3 x 4

Multiply: 3 x 4 = 12

= 3x + 12

3x + 12 = -x - 8

Subtract 12 from both sides!

3x + 12 - 12 = -x - 8 - 12

Simplify!

3x = -x - 20

Add x to both sides!

3x + x = -x - 20 + x

Simplify!

4x/4 = -20/4

Simplify 4x/4 : x

Divide the numbers!

4/4 = 1 = x

Simplify!

-20/4 : -5

-20/4

Apply the fraction rule! : -a/b = -a/b

= -20/4

Divide the numbers!

20/4 = 5

= -5

x = -5

Answer:

A:150

Step-by-step explanation:

Answer:

f(p) = 6p + 50

Step-by-step explanation:

f(p) = 6p + 50

where f(p) is the total money for the laptop ($335) and p is the monthly payment.

If you wanted to plug in the total cost of the laptop the equation would be 335 = 6p + 50.

Answer:

x = 120, y = 160

Step-by-step explanation:

I like to use the elimination strategy in this type of problem.

You need to get one of the terms on the right side of the equation equal to and opposite another term on the right side of the other equation. For example, I'm going to make the y term of the first equation equal and opposite the y term of the second equation by multiplying the entire first equation by -1.5.

-1.5 * (x + y) = (280) * -1.5

2.5x + 1.5y = 540

The new equations are (only the first one changed):

-1.5x - 1.5y = -420

2.5x + 1.5y = 540

-----------------------------------

x = 120

Then plug this back into one of the equations.

(120) + y = 280

y = 160

You can check by plugging these into the other equation to make sure they are correct.

Answer:

3. 9

4. 5 pounds

5. 5/12 of a pound

Step-by-step explanation:

3. "at least 3/8" means to include that column in the count.

4. 3(1/4) + 4(3/8 ) + 3(1/2) + 2(5/8)

= 3/4 + 12/8 + 3/2 + 10/8 but we need a common denominator. LMK in the comments if you need help with that

= 6/8 + 12/8 + 12/8 + 10/8

= 40/8

= 5 pounds.

5. For the average, we add up all the weights, then divide by the number of kittens. Thankfully, we just added everything up in #4. Since we're going to be dividing 5 by 12, we'll end up with a decimal. But since the whole problem was written in fractions, we'll keep it in fractions.

40/8 divided by 12 kittens

40/8 divided by 12 = 40/8 muliplied by the inverse of 12 which is 1/12

40/8 x 1/12

= 40/96

Our numerator and denominator can be evenly dived by 8, so the fraction is reduced to

= 5/12

Answer: $3.25

Step-by-step explanation: The computation of the cost of a veggie wrap is shown below:

Let us assume the veggie strap be x

And the turkey wrap be y

Now the equations are

6x + 12y = $64.50

x + 2y = $10.75

8x + 8y = $56

x + y = 7

Now

x + 2y = $10.75

x + y = $7

y = $3.75

So x = $7 - 3.75

= $3.25

So, the correct option is option (B).

To understand the calculations, check below.

Simultaneous linear equations are the system of two linear equations in two or three variables that are solved together to find a common solution. The simultaneous linear equation is represented as follows:

[tex]a_1x+b_1y=c_1\\a_2x+b_2y=c_2[/tex]

It is given that,

[tex]x[/tex] represents the cost of a veggie wrap and  [tex]y[/tex] represents the cost of a turkey wrap.

Now, using the first part of the given question we get,

[tex]6x+12y=64.50...(1)[/tex]

Again in the second part of the given question is 8 veggies wraps 8 turkey wraps and costs $56 then we get the equation as,

[tex]8x+8y=56...(2)[/tex]

Then from equations (1) and (2) we get the equation as,

[tex]6x+12y=64.50\\8x+8y=56[/tex]

Answer:

Part A:

Part B: The hardware store is cheaper.

Step-by-step explanation:

Part A:

At the hardware store, the ladder is 350 plus 6% tax. To solve this you would multiply 350 by 1.06 tax. Then you would get 371. Online, the ladder is 320 plus 6% tax and 5% shipping. To solve this you would multiply 320 by 1.11 (tax and shipping combined). Then you would get 355.20.

Part B:

To solve the cost of the ladder at the hardware store, you would need to first multiply 350 by 0.9 for the 10% discount. That would get you 315. Then add the 6% tax to get 333.90. To solve for the online ladder, you would need to multiply 320 by 1.06 (6%), and get an answer of 339.20. This means that the hardware store is cheaper.

Answer

Step-by-step explanation: How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

Cost of ladder= $320

Sales tax of shipping and handling is 5% and 6%

Off on hardware= 10%

Now,

PART A:

At the online store, the ladder costs $320, and the sales tax is 6% of $320, which is:

$320 x 0.06 = $19.20

The shipping and handling is 5% of $320, which is:

$320 x 0.05 = $16

So the total cost of buying the ladder online is:

$320 + $19.20 + $16 = $355.20

At the physical store, the ladder costs $350, and the sales tax is 6% of $350, which is:

$350 x 0.06 = $21

So the total cost of buying the ladder at the physical store is:

$350 + $21 = $371

Therefore, buying the ladder online would be cheaper, with a total cost of $355.20.

PART B:

If the hardware store is offering 10% off the price of the ladder, the cost of the ladder would be:

$350 x 0.1 = $35 off

$350 - $35 = $315

So the total cost of buying the ladder at the physical store with the discount would be:

$315 + $18.90 (6% sales tax) = $333.90

If the online store is offering free shipping and handling, the total cost of buying the ladder online would be the same as the cost of the ladder:

$320 + $19.20 (6% sales tax) = $339.20
