Answer 1

Answer:

x = 15

Step-by-step explanation:

First, you cross multiply both terms:

5 * 12 = 4 * x

Then, you simplify it.

60 = 4x

(60 = 4x)/4 =

15 = x

Answer 2

Answer:

x=15

Step-by-step explanation:

\(\frac{5}{4}=\frac{x}{12}\\\)

5/4 is a proportion that is equivalent to x/12, like how 1/4 is proportional to 25/100. Cross multiply to find the missing values.

➡\(5*12=4*x\)

➡\(60=4x\)

➡\(\frac{60}{4} =x\)

➡\(x=15\)

Word Problems (WITH EXPLANATION)

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.

Word Problems (WITH EXPLANATION)In the rectangle below, the line MN cuts the rectangle into two regions.

Answers

The length of segment NB is 0.833

Finding x, the length of segment NB

From the question, we have the following parameters that can be used in our computation:

The rectangle

The area of the rectangle is

Area = (20 + x) * 10

The area of MNBC is

Area  = 1/2 * 10 * (x + 20 + x - 5)

Area  = 5(2x + 15 )

The area of the quadrilateral MNBC is 40% of the total area of the rectangle

So, we have

5(2x + 15) = 40% * (20 + x) * 10

5(2x + 15) = 4* (20 + x)

When evaluated, we have

x = 0.833

#SPJ1

Answer:

X=1

Step-by-step explanation:

The total area of the rectangle is 20x10=200

so the area of MNBC is: 40%x200=80

MC= 20-5=15

so (x+15).10/2=80 (according to the trapezoidal area formula)

x=1

so the answer is 1

Step-by-step explanation:

i believe what you need help on is simplifying the equations. so let's start with the first one.

====================================================================

(2x+1)(x+5) original problem

(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.

2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.

2x2+11x+5 this is the most simplified equation.

====================================================================

6x−4xy original problem.

unlike the last problem, we can easily just... 6x + (−4xy).

−4xy+6x this is the most simplified equation.

====================================================================

ok, the last one. phew!

unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.

if we factored, we would get...

(4x+5)(4x−5)

Answers

Answer:

[ 2] − | −5 + 7 |

Step-by-step explanation:

Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.

Step 1) Solve. | −5 + 7 | = 2.

Step 2) Find which other absolute value is equal to -2.

After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.

We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0

To solve this problem, we need to simplify each expression and see which one, when added to | −5 + 7 |, will equal zero.

We start by simplifying | −5 + 7 |:

| −5 + 7 | = | 2 | = 2

Now we can simplify each of the answer choices:

[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2

We see that only choice [2], when added to | −5 + 7 |, will equal zero:

2 + (−2) = 0

Therefore, the answer is [2] | +5 − 7 |.

I got 11/12

Step-by-step explanation:

Because you would take 2/3 × 1/4

They don't have the same denominators so you have to find a multiple. 12 is a multiple of both 3 and 4. In order to get a denominator of 12 for 2/3 you would have to multiply 3 by 4 and 2 by 4 leaving you with 8/12. Then you would have to multiply 1 by 3 and 4 by 3 leaving you with 3/12. Then you add them giving you 11/12. Hope this helps

Devin wants to use his 12% employee discount to buy a video game that is priced at $57.80. A 8.75% sales tax is applied to the discounted price. What will be the total cost of the video game, including the sales tax?

Answers

Answer:

43.73

Step-by-step explanation:

use a calculater

First you need to find the price of the video game after Devin’s employee discount. To do this you multiply the original price times the discount:

$57.80 * 0.12 = $6.94

Now subtract the discount from the original price:

$57.80 - $6.94 = $50.86

Now we need to multiply the discounted price and the sales gas rate to see how much taxes will be added to our purchase:

$50.86 * 0.0875 = $4.45

Finally we add our discounted price plus the sales tax to find the total cost of the video game after the employee discount:

$50.86 + $4.45 = $55.31

Answers

G=266-42t and S=332-53t are equations to determine the number hours after noon t, when Genesis and Skylar are the same distance from the stadium

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Genesis is 266 miles away from the stadium.

Genesis is driving along the highway at a speed of 42 miles per hour.

Skylar is 332 miles away from the stadium.

Skylar is driving at speed of 53 miles per hour

Let G represent Genesis' distance, in miles, away from the stadium t hours after noon.

Let S represent Skylar's distance, in miles, away from the stadium t hours after noon.

We need to find an equation for each situation, in terms of t, and determine the number hours after noon t when Genesis and Skylar are the same distance from the stadium.

G=266-42t

S=332-53t

266-42t=332-53t

53t-42t=332-266

11t=66

Divide both sides by 11

t=6 hours

Hence, G=266-42t and S=332-53t are equations to determine the number hours after noon t, when Genesis and Skylar are the same distance from the stadium
