5:15 pm is the answer for the question

Answer:

The unit rate is 35 miles per hour

Step-by-step explanation:

Answer: adults = $10

Step-by-step explanation:

x = adults

y = children

2x + 2y = 30

2x + 3y = 35

Using the elimination method:

2x + 2y = 30

-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)

Solve for y...

2y = 30

-3y = -35

Add together...

-y = -5

Multiply by -1 to give positive value for y...

y = $5

Plug into one of the original equation to find x...

2x + 10 = 30

2x = 20

x = $10

Answer:

The other integer is less than -80

Step-by-step explanation:

The given sum of the two integers < -57

The value of one of the integers = 23

Let 'b' represent the value of the other integer, we are given;

b + 23 < -57

Therefore, we have;

b < -57 - 23 = -80

Therefore, the other integer, b < -80.

Answer:

Let me give you an example of a segment addition problem that uses three points that asks the student to solve for x but has a solution x = 20.

First, I assumed values for each x, y and z and then manipulated their coefficients to get the total at the end of each equation.

20 + 10 +30 = 60

40 + 0 + 40 = 80

40 + 10 = 50

Then exchangeing these numbers into values and we have the following equation.

x + 2y + 3z = 60

2x + 4z = 80

2x + z = 50

If you will solve them manually by substituting their variables into these equations, you can get

x = 20

y = 5

z = 10

Answer:Jim gets £24

Step-by-step explanation:

Let the amount Natasha gets be represented as x

SO that Krutika getting  three times as much as Natasha be represented as 3x

AND Jim getting  twice as much as Krutika  be represented as 2 x 3x=6x

The equation to show how much each gets can be represented as

x + 3x  +6x=40

Solving

x +3x + 6x=40

10x =40

x =40/10 =4

Natasha gets £4

Krutika gets 3x =3x4= £12

Jim gets 6x=6 x4= £24

Answer:

13.5 euros

Step-by-step explanation:

A partir de la pregunta anterior, las dimensiones del terreno se dieron como 0.3 & 0.9 m

El terreno es de forma rectangular.

Paso 1

Encontramos el área de la tierra

Área = Largo × Ancho

Área = 0.3 m × 0.9 m

Superficie = 0.27m²

Paso 2

Nos dijeron

1 m² = 50 euros

0.27m² = x

Multiplicar cruzada

x = 0.27 × 50 euros

x = 13.5 euros

Answer:

5.50 + 0.88r ≤ 26.00; 24 rides

or 5.50 + 0.88r ≤ 26.00; 23 rides

Step-by-step explanation:

mrk me brainliest plz

i can't explain it i just look at a math problem and auotomatically know the answer

Answer:

(1) 5.50 + 0.88r ≤ 26.00; 23 rides

Step-by-step explanation:

First of all, please understand the equation itself. We are multiplying 0.88 by r, or the number of rides. First, lets determine how many rides Elisha can ride. 0.88 * 23 = 20.24. And 20.24 + 5.50 = 25.74. This is less than 26.00. Now, 0.88 * 24 = 21.12 + 5.50 = 26.7. Though not by much, this is more than 26.00, so, Elisha cannot ride more than 23 rides. That eliminates options (3) and (4). The difference between (1) and (2) is that in (1) we are multiplying 0.88 by r which is correct, however, option (2) is multiplying 5.50 by r which is incorrect. Thus we have our answer. However, please note one important thing. I want you to understand the reason for the "≤" sign as this is very different from <. The sign used here indicates "less than OR equal to" whereas the other is "less than." The sign used indicates that this is the MAX Elisha can spend but he could also spend less. This may seem simple but it is crucial to have a good understanding of this concept as you progress. Any further questions just comment! Hope this helps:) P.S. do not just take the answer! READ, PRACTICE, AND UNDERSTAND.

Answer:

Speed of plane is 250 miles per hour and speed of wind is 50 miles per hour

Step-by-step explanation:

Let x represent the speed of the wind. When travelling with the wind, the plane travels 1200 miles within 4 hours. Hence the speed of the plane with the wind is:

speed = distance / time = 1200 miles / 4 hours = 300 miles per hour

When travelling against the wind, the plane travels 1200 miles within 6 hours. Hence the speed of the plane against the wind is:

speed = distance / time = 1200 miles / 6 hours = 200 miles per hour

Therefore:

300 - x = 200 + x

300 - 200 = x + x

2x = 100

x = 50 miles per hour

The speed of the wind = 50 miles per hour. The speed of the plane = 300 - 50 = 200 + 50 = 250 miles per hour

Answer: Trinomial

Step-by-step explanation: This expression has 3 terms (2a^2, -5a, and 7), so it is a trinomial. An easy way to remember this is that 'tri' = 3, 'bi' = 2, and 'mono' = 1. Hope this helped :)

Answer:

6 and 2/8 or reduced to 6 and 1/4

Step-by-step explanation:

first we will find angle BED = 180 - 49 = 131 degrees

then find angle BDE = 90 - 64 = 26

then subtract the sum of both from 180

180-26+131=23 degrees

Answer:

1/4

Step-by-step explanation:

First, you add all the marbles together to make the total. 6 + 5 + 4 + 9 = 24.

Then, make 6 the numerator and 24 the denominator. [tex]\frac{6}{24}[/tex]

Next, simplify. [tex]\frac{6}{24}[/tex] = [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

Step-by-step explanation:

Given inequality:

Solution:

The only number satisfying this inequality is 0.

Correct choice is A

You would use this formula for the problem...

(C=2πr) The circumference equals 2 multiplied by pi and radius.

In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.

C=2π(2) since 2 is half of 4, that's your radius.

Your answer is roughly C= 12.57.

You're welcome.

Answer:

k = 27/4

y = 283.5

Step-by-step explanation:

Let

y = amount of water used

x = number of dogs washed

y = kx

y = 81 gallons

x = 12 dogs

y = kx

81 = k * 12

81 = 12k

Divide both sides by 12

81/12 = 12k/12

k = 81/12

k = 27/4

k = 6.75

Find x when y = 42 dogs

y = kx

y = 27/4 * 42

y = (27*42) / 4

y = 1,134 / 4

y = 283.5

y = amount of water used = 283.5 gallons
