Answer:

y=1

Step-by-step explanation:

5y(2x-1)=y(x+2)+20, x=3

5y(2(3)-1)=y(3+2)+20

5y(6-1)=y(5)+20

5y(5)=5y+20

25y=5y+20

25y-5y=20

20y=20

y=20/20

y=1

5y(2x-1)=y(x+2)+20, x=3​

Step 1: Substitute x with 3

5y(2(3) - 1) = y(3 + 2) + 20

Step 2: Combine like terms in the parentheses

5y(6 - 1) = y(3 + 2) + 20

5y(5) = y(3 + 2) + 20

5y(5) = y(5) + 20

Step 2: Distribute the number outside the parentheses to the numbers inside the parentheses

25y  = 5y + 20

Step 3: Combine like terms by subtracting 5y to both sides

25y-5y  = (5y-5y) + 20

20y = 20

Step 4: Divide 20 to both sides to isolate y

[tex]\frac{20y}{20} = \frac{20}{20}[/tex]

y = 1

Check:

5(1) (2(3) - 1) = 1(3+2) + 20

5(6-1) = 1(5) + 20

5(5) = 5 + 20

25 = 25

Answer:

Volume  = 40in^3

Step-by-step explanation:

The volume of a box is:

Volume = width x lenght x height

Where:

width: 4in

Length: 5in

Height = 2in

Then: Volume = width x lenght x height = 4in x 5in x 2in = 40in^3

ANSWER

The volume is 40 cubic inches.

EXPLANATION

The dimensions of the box are ,

width, w=4 inches

height, h=2 inches

and

length, l=5 inches

The box is a rectangular prism.

The formula for finding the volume of a rectangular prism is

[tex]V=l \times b \times h[/tex]

We substitute the values to get,

[tex]V=4\times 5 \times 2 = 40 {in}^{3} [/tex]

Answer is

(-16 , 14)

Answer:

-16, 14

Step-by-step explanation:

Answer:

50%

Step-by-step explanation

Each quartile of a box plot contains 25% of the data.

45-48 minutes is 25%

48-53 minutes is 25%

53-56 minutes is 25%

56-64 minutes is 25%

The questions asks for the percentage from 48-56.

48-53 is 25% and 53-56 is 25%. If you add 25% + 25%, you get 50%

Therefore, the percentage of village women who took 48-56 minutes to collect one container of water if 50%.

The total space bought for the two ads in the newspaper is 3/4 of a page. This is determined by adding the fractions representing the size of each ad together: 5/8 + 1/8 = 6/8, which simplifies to 3/4.

You are dealing with fractions in this mathematics problem. If you bought two ads, one taking 5/8 of a page and the other taking 1/8 of a page, you need to add these fractions together to find out how much space you bought for ads overall.

Adding the fractions 5/8 and 1/8 would give you:

5/8 + 1/8 = 6/8

The fraction 6/8 can be simplified further by dividing both numbers by their greatest common divisor (which is 2), resulting in:

6/8 = 3/4

Therefore, the ads took up 3/4 of a page in total.

you bought a total of 3/4 of a page for ads.

To calculate the total space bought for ads in a newspaper, simply add the proportions of the page that each ad takes up. The first ad covers 5/8 of a page, while the second ad occupies 1/8 of a page. Adding these together:

5/8 + 1/8 of a page

This can be calculated by adding the numerators and keeping the denominator the same since both fractions have the same denominator.

Add the numerators: 5 + 1 = 6

Keep the denominator the same: 8

Combine them to get the new fraction: 6/8 of a page

However, notice that 6/8 can be simplified to 3/4, because both the numerator and the denominator can be divided by 2.

Therefore, you bought a total of 3/4 of a page for ads.

Answer:

3/28

Step-by-step explanation:

Given in the question that,

stack of cards have numbers (1, 1, 2, 2, 3, 3, 3, 4)

Total number of cards = 8

Number of card with 3 on them = 3

Number of card with 2 on them = 2

To find the probability that he pulls out a 3 first and then pulls out a 2, we will multiple the probability of having 3 with 2.

Probability of having 3 = 3/8

Probability of having 2 = 2/7 (without replacing)

3/8 x 2/7 = 3/28

Thus, the answer is 3/28

Bill and Ted ask two local t-shirt companies to give them a price. * Patty's Printing charges $21.50 for each t-shirt. * Sandra's shirts has a one-time set up fee for $63 and then charges $18 for each t-sh

Patty's Printing= 21.5x

Sandra's Shirts = 63+ 18x

The approximate area that is shaded blue 77 in².

In this question we simply calculate area of circle where r=5 , and area of rectangle l = 2 and b = 1.

   Area of circle = πr²

                           = [tex]\frac{22 *5*5}{7}[/tex] = 78.57

Area of rectangle = l * b

                              2 * 1 = 2

 Then simply subtract area of rectangle to area of circle .

Area of shaded blue = 78.57 - 2

                                 = 76.57 ⇒ 77 in²

Therefore, The approximate area that is shaded blue 77 in².

Answer:

the inequality would be: 89+41+17.50x Is less than 200

Step-by-step explanation:

add all of the numbers together and the x with the 17.50. Add a less than inequality sign, then 200, which represents how much it would be for repairs

Answer:

[tex]130+17.50x \leq 200[/tex]

Step-by-step explanation:

The appliance repair company will repair his microwave for a service call fee of $89, a parts fee of $41, and a charge of $17.50 for every 15 minutes of labor.

If Josh spends $200 or more on repairs, he will replace the microwave.

Let x represents the number of 15-minute intervals of labor.

So, as per the scenario, the inequality becomes:

[tex]89+41+17.50x \leq 200[/tex]

=> [tex]130+17.50x \leq 200[/tex]

Solving for x

[tex]17.50x \leq 200-130[/tex]

[tex]17.50x \leq 70[/tex]

[tex]x \leq 4[/tex]

Hence, up to 4, 15 minutes interval that is one hour. the repair cost will be up to $200.

But after this it will cost more. Hence, Josh can opt for replacing after 4, 15 minutes intervals.

Answer:

the correct option is option c.

Step-by-step explanation:

We have the expression: (160*243)^1/5

First, we know that 160 = 5(2^5)

And, 243 = 3^5

Then we have: (160*243)^1/5 = [5(2^5)(3^5)]^1/5 = 6(5)^1/5

So the correct option is option c.

Hello! :)

Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5%.

Hope I helped and answered in time!

Answer:

f(2) = 0

Step-by-step explanation:

Function f(t) is defined in three different ways depending on the value of t.

For t = 8, function f(t) is -64/t.

For t = 10, function f(t) is 14 - t.

We are not asked about f(8) or f(10). We are asked about f(2). The third definition of function f(t) is for all values of t that are not 8 or 10. 2 is not 8 or 10, so use the third definition of function f(t) and plug in 2 for t.

f(t) = t^2 - 3t + 2 for t not equal to 8 or 10.

f(2) = 2^2 - 3(2) + 2

f(2) = 4 - 6 + 2

f(2) = 0
