When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?
10x-25y+18-25x+10y-3
-15x-15y+15
-10x+25y+18+25x-10y+3
35x-35y+21

Answers

Answer 1

Answer:

35x-35y+21

Step-by-step explanation:

You would have to combine the like terms together to get 35x-35y+21.

Answer 2

By applying algebra properties we notice that the algebraic expression 0.5 · (20 · x - 50 · y + 36) - 0.25 · (- 100 · x + 40 · y - 12) is equivalent to 35 · x - 35 · y + 21. (Correct choice: D) #SPJ5

Mia is collecting boxes to help her friend move. She found a box that is 4 ft. Wide, 3 ft. High, and 2 ft. Long. How much space would the box take up in the moving truck?

Answers

Answer: 24 ft³

Step-by-step explanation:

To calculate the amount of space that the box will take up in the moving truck, we are simply meant to calculate the volume. This will be:

= Length × Width × Height

= 2 × 4 × 3

= 24 ft³

Therefore, the space that the box will take up in the moving truck is 24 ft.

A stick is twice as long as a piece of string. If you have 10 strings and 10 sticks laid out in a line, the line measures 90 inches. How long is the stick?

Answers

the stick is 6 inches. if the stick is 6 and the string is 3 then the stick is double the string. if you multiply them both by ten because there is 10 each, you get 60 and 30. if you add them together you get 90 inches so the stick is 6 in. :))

Answers

Answer:

This represents the graph area above the line y = 4x - 5 shaded.

Step-by-step explanation:

y > 4x - 5 is an inequality.  First we graph y = 4x - 5, which has y-intercept (0, -5) and slope 4.  Next, we shade all of the area above this line (because the inequality y > 4x - 5 says that all y values are above 4x - 5).

Answers

Answer:

7 lbs. or option B.

Step-by-step explanation:

To figure out how much the chairs weigh to then divide them, you first need to subtract 36 from 92.

92 - 36 = 56

Now, we have to divide 56 by the number of chairs we have because we need to find out how much a single chair weighs.

56 ÷ 8 = 7

So, each chair weighs 7 lbs.

Answer:

B) 7 lbs

Step-by-step explanation:

To find how much the chairs weigh, you must subtract 36 from 92.

92 - 36 = 56

We have to divide 56 by 8 or the number of chairs.

56 ÷ 8 = 7

B) 7 lbs

A coffee shop sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month Kim spent $31.75 on a mug and refills. Write an equation you can use to find the number of refills Kim bought. How many refills did Kim buy?

Answers

Answer:

equation: x(1.25) + 6.75 = 31.75 refills: 20

Step-by-step explanation:

The mug costs $6.75, and you aren't buying multiple cups, so that number stays the same. The number of refills is "x" since we do not know the amount. Next to "x" we multiply 1.25 for the cost of each refill. So now we have "x(1.25)" then we add $6.75 to the equation, for the mug price. Along with the total at the end. To which we now have "x(1.25) + 6.75 = 31.75"

Now we solve the equation. First, subtract 6.75 from each side

x(1.25) + 6.25 = 31.75

            -6.25    -6.25

Now we have "x(1.25) = 25" So we have to divide each side by 1.25

x(1.25/1.25) = 25/1.25

                x = 20

Therefore, Kim bought 20 refills. To check our work we can replace x with 20 in the original equation.

20(1.25) + 6.75 = 31.75

        25 + 6.75 = 31.75

                31.75 = 31.75

I'm not the best at explanations, but I hope this helped! :)
