The solution is, 12 multiple-choice questions are on the test.

What is  simplification?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

The right answer for the question that is being asked and shown above is that:

m + f = 15 ---> 3m + 3f = 45

3m + 5f = 51

now, we have.

3m + 3f = 45

3m + 5f = 51

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

-2f = -6

f = 3

so, we get,

m + f = 15

m = 15 - 3

m = 12

So the correct answer is 12.

Hence, The solution is, 12 multiple-choice questions are on the test.

How much does one slice of pumpkin pie cost if there are 8 servings per pie?
Ingredients
• Pumpkin 15oz can ($1.50 for 15oz can)
2 eggs ($2.59 for one dozen)
• 1 tsp pumpkin pie spice ($5.99 for 1.12oz Jar =
approx.6tsp)
• Evaporated Milk 14oz can ($1.25 for 14oz can)
• Pillsbury Pie Crust ($3.79 for two crusts)
Show Your Work Here:

Answers

Answer:

$0.76 per serving of pumpkin pie

Step-by-step explanation:

the total cost of the ingredients needed to prepare a pumpkin pie = $1.50 + ($2.59 / 6) + ($5.99 / 6) + $1.25 + ($3.79 / 2) = $6.075

if we cut 8 servings per pie, then the cost per serving = total cost of the pie / number of servings = $6.075 / 8 = $0.759375 ≈ $0.76 per serving of pumpkin pie

We want to find the cost of each slice of a pie given that we know the price of the ingredients that we use to make the whole pie. We will see that the cost of a single slice is $0.75.

First, we must get the cost of the whole pie. We have:

$1.50 for the 15oz can of PumpkinWe know that 12 eggs cost $2.59, then 2 eggs cost: (2/12)*$2.59 = $0.43.We know that 1.12 oz of pie spice costs $5.99, and we use only one teaspoon of this, remember that: 1tsp = 0.167 oz, Then the cost of 1tsp of pie spice is: (0.167 oz)/(1.12 oz)*$5.99 = $0.89.$1.25 for the 14oz can of evaporated milk.One pie crust, we know that two of them cost $3,79, then only one costs: $3.79/2 = $1.90

The total cost is then:

C = $1.50 + $0.43 + $0.89 + $1.25 + $1.90 = $5.97

Now we know the total cost of the pie, and it has 8 slices, then each slice costs: $5.97/8 = $0.75

Inequality form x less than or equal to -13

Step-by-step explanation

Answer:

x ≤ -13

Step-by-step explanation:

2(x + 1) - 3(x + 5) ≥ 0

Distribute the 2

(2 × x) + (2 × 1)

2x + 2 - 3(x + 5) ≥ 0

Distribute the -3

(-3 × x) + (-3 × 5)

2x + 2 - 3x + (-15) ≥ 0

2x + 2 - 3x - 15 ≥ 0

Combine like terms

2x - 3x + 2 - 15 ≥ 0

-x + (-13) ≥ 0

-x - 13 ≥ 0

   +13    +13

-x ≥ 13

Divide both sides by -1 and flip the sign

Answer:

y=3/2x+5/2

Step-by-step explanation:

I used the Y2-Y1/X2-X1

In this equation you can see that there are 2 points (-5,-5) and (1,4)

If you substitute, you will get

4+5/1+5

9/6 and if you simplify this, you will get 3/2

Now that we have the slope, we just have to use y=mx+b

(I'm using the point (1,4))  4=3/2(1)+b

                                         4=3/2+b

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy

Answers

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops
