136 ft²

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.

a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?

answer for a: $95 + $55 = $150

b. Is there a proportional relationship between time and the cost of the cell phone plan?

answer for b: There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55.

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:

180-80=100

100-38=62

MJL=62

angle(m)=80

Answer:

<MJL = 62°

<m = 80°

x = 4

Step-by-step explanation:

in ∆JKL total angle aum is 180° and to find <L we have to subtract the given angles in this triangle from 180

that is

<L = 180-80-38 = 62°

then <MJL = 62° (alternative interior angle)

<JLM= 38° (alternative interior angle)

then <m = 180-62-38 = 80°

6x = 24 ( opposite sides are equal in parallelogram)

x= 24/6

x = 4

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

Given:

Macy has 8 quarters and 24 pennies in her pocket.

To find:

The answer that correctly shows the ratio of this comparison.

Solution:

We know that,

Number of quarters = 8

Number of pennies = 24

The ratio of this comparison is:

[tex]Ratio=\dfrac{Quarters}{Pennies}[/tex]

[tex]Ratio=\dfrac{8}{24}[/tex]

[tex]Ratio=\dfrac{1}{3}[/tex]

[tex]Ratio=1:3[/tex]

Therefore, the required ratio is 8:24 and its simplified form is 1:3.
