PLEASE HELP!!!!! Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12. What does the solution to the system of equations represent in the context of the problem? Explain.

Answer:

y=-2/3x+108

Step-by-step explanation:

If you look at the graph for "perfect points"(that's what I call them) you can get rise over run aka slope. In this case, it's -2/3. As for the y-intercept, following the graph's pattern, the y-intercept is 108. Just substitute the values into y=mx+b.

Answer:

20

Step-by-step explanation:

5-1=4×5=20 that's why

Answer:

x = 20

Step-by-step explanation:

[tex]\frac{x}{5} + 1 = 5[/tex]

isolate the [tex]\frac{x}{5}[/tex] by subtracting 1 from both sides

[tex]\frac{x}{5} + 1 -1 = 5-1[/tex]

[tex]\frac{x}{5} = 4[/tex]

then isolate the x by multiplying both sides by 5

[tex]\frac{x}{5} * 5 = 4 * 5[/tex]

[tex]x = 4 *5 = 20[/tex]

so

[tex]x = 20[/tex]

hope this helps :))

Answer:

C.

Step-by-step explanation:

The sales tax is ≈ 12.74

The total of $93 - (12.74 + 73.89)  = 6.37

$6.37 is approximatley 20%

The description of the service they received is

They left a 20% tip, so the service was probably above average.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

let the amount of tax be x.

So, 100% of x = 73.89 x 5.8%

x = 428.562/100

x= 4.285

Now, the tip amount would be

= 93 - 73.89 4.28

= $14.83

Now, the amount of tip in percent is

73.89 / 100 = 14.83 / x

x = 14.83 /0.7389

x= 20.07

x= 20%

Answer: The factors of 14 are 14, 7, 2, 1.

             The factors of 55 are 55, 11, 5, 1.

The common factors of 14 and 55 are 1, intersecting the two sets above.

In the intersection factors of 14 factors of 55 the greatest element is 1.

Therefore, the greatest common factor of 14 and 55 is 1.

Step-by-step explanation:

The greatest common factor of 14 and 55 is 1.

To find the greatest common factor of 14 and 55.

First write the factor of 14.

14 × 1 = 14, 7 × 2 = 14, 2 × 7 = 14, 1 × 14 = 14.

Which are 14, 7, 2 and 1.

Now, write the factor of 55.

55 × 1 = 55, 11 × 5 = 55, 5 × 11 = 55, 1 × 55 = 55

Which are 55, 11, 5 and 1

Therefore, the common factor of 14 and 55 is 1.

Step-by-step explanation:

(x-2)(x-1)

You need to take the first x and multiply by the other x. Then multiply the first x by the -1. Do this for the -2 also. -2 by the second x and -2 by the -1.

You get x^2-x-2x+2 then combine terms.

Answer:

Length of DE = 2.90 (Approx)

Step-by-step explanation:

Given:

AE = 7[tex]\frac{5}{8}[/tex]cm = 61 / 8 cm = 7.625 cm

AB = BC

CD = 1/2 cm = 0.5 cm

DE is 3/8 more than AB

Find:

Length of DE

Computation:

Assume;

AB = BC = x

So,

DE = x + 3/8(x) = [11 / 8]x = [1.375]x cm

AE = AB + BC + CD + DE

7.625 = x + x + 0.5 + [1.375]x

7.125 = 3.375 x

x = 2.1111 (Approx)

Length of DE = [1.375][2.111]

Length of DE = 2.90 (Approx)

Answer:

y = x + 2.5 or y = x + 5/2

Step-by-step explanation:

Multiply both sides by 2 so that they are not fractions anymore.

[tex](2)\frac{2y}{2} = \frac{2x}{2} + \frac{5}{2} (2)\\[/tex] This gives you...

2y = 2x + 5 (divide both sides by 2 to get the y alone.)

y = x + 2.5

The two clowns charge the same amount of money at 16.66 hours.

Payment for work based on hours worked (or sometimes per day or per amount of work done).

Here, let the duration of birthday party be x hours.

For Clown A,

Initial fee = $ 105

Additional charge = $ 9 per hour

Total amount of clown A = $ (9x + 105)   ...........(i)

For Clown B,

Initial fee = $ 155

Additional charge = $ 6 per hour

Total amount of clown B = $ (6x + 155)   ...........(i)

Now, according to question

9x + 105 = 6x + 155

9x - 6x = 155 - 105

3x = 50

x = 50/3

x = 16.66 hours

Thus, the two clowns charge the same amount of money at 16.66 hours.
