Step-by-step explanation:

Just easy

Answer:

first is A

then is B

Step-by-step explanation:

your welcome

Answer:

i think B but I’m not 100% sure lol

Step-by-step explanation:

Here’s what I found on this app

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

2w + 8 = 4w - 2w + 8

2w + 8 = 2w + 8

0 = 0

Answer:  C. 3w + 8 – w = 4w – 2(w – 4)

Identity equations are equations that are true no matter what value is plugged in for the variable. If you simplify an identity equation, you'll ALWAYS get a true statement. Learn about identity equations in this tutorial, and then create your own identity equation.

Step-by-step explanation:  Algebra.com

a. 11 - (2v + 3) = -2v - 8

Simplify

    11 - 2v - 6 = -2v - 8

         5 - 2v = -2v - 8

Add 3v to both sides

              5 = -8

That's false, so it is not an identity.

b. 5w + 8 - w = 6w - 2(w - 4)  

Simplify

      4w + 8 = 6w - 2w + 8

      4w + 8 = 4w + 8

That's exactly the same on both sides, so it's

an identity.

c. 7m - 2 = 8m + 4 - m

  7m - 2 = 7m + 4

Subtract 7m from both sides:

      -2 = 4

That's false, so it is not an identity.

d. 8y + 9 = 8y - 3

Subtract 8y from both sides:

       9 = -3

That's false, so it is not an identity.

Answer:

$75 + $17.50t

$56 + $19.50t

Step-by-step explanation:

Let us assume the number of hours be t

Now according to the equation

For Joe

= $75 + $17.50t

And, for Maddie

= $56 + $19.50t

The expression that represents the total is as

$75 + $17.50t

$56 + $19.50t

Hence, the above represent the answer and the same is relevant

Answer:

191 students  B option is correct

Step-by-step explanation:

Total students=464

The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let m represent the number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain.

Hence:

(48/2)m < 256

24m < 256

The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256

Answer:

i ) $96120

ii ) Singular adult fee in 2012: $186.91

Step-by-step explanation:

( i )

To find the costs of all 560 peoples you:

Multiply the amount of people by the fee,

440 × 198 = $87120

120 × 120 = $9000

Add these go get the sum of member fees: $96120

( ii )

First calculate what 1% of the adult fee would be:

198 ÷ 100 = 1.98 = 1%

Then calculate what 0.1% of the fee:

1.98  ÷ 10 = 0.198 = 0.1%

Now multiply 5 by the value of 1% to get 5% :

5 × 1.98 = 9.9

Then multiply 6 by the  0.1% to get 0.6% :

0.198 × 6 = 1.188

Add these numbers together to get:

1.188 + 9.9 = $11.088 = 5.6%

Due to the fact this question is referring to money we will round this number 2 decimal places (as money does not exceed 2dp)

$11.09

We now subtract this from the 2013 fee to find out the 2012 fee

$198 - $11.09 = $186.91

$186.91 was the cost of a singular adult fee in 2012

2(x - 3) = 2x + 5     distribute by multiply 2 into the parenthesis.

2x - 6 = 2x + 5

-2x        -2x         subtract 2x on both sides, 2x's will cancel on both sides.

-6 = 5

Since -6 = 5, there is no solution because -6 cannot equal to 5, which is a false statement. Thus, "C. There is no solution." is the correct answer. Hope this helps :)

Answer:

[tex] \frac{x - 10}{8} [/tex]

Step-by-step explanation:

[tex] \frac{3x}{8} - \frac{x + 5}{4} [/tex]

The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.

Thus:

[tex] \frac{1(3x) - 2(x + 5)}{8} [/tex]

[tex] \frac{3x - 2x - 10}{8} [/tex]

[tex] \frac{x - 10}{8} [/tex]

Answer: 96.12

Step-by-step explanation:

The amount that Bill will need to save will be for the cost of the headphones and the sales tax that will be applied. This will be:
