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:

x = 74.7m

Step-by-step explanation:

[tex] \sin(42) = \frac{50}{x} \\ 0.67 = \frac{50}{x} \\ x = 50 \div 0.67 \\ x = 74.7m[/tex]

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:

If you change the order of the numbers when adding or multiplying, the result is the same. Use the commutative properties to rewrite the following expressions: Use the commutative property of addition to change the order. Use the commutative property of multiplication to change the order. Use the commutative properties to rewrite the following:

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

L*W=A divided by 2

Answer:

189.27in^2

Step-by-step explanation:

Area of the rectangle is l*w

15*10= 150

Area of the circle is π r^2

We don't have radius but we have diameter so 10/2 =5

so A= π 5^2

78.53982, but we need half that since its only half a circle.

78.53982/2 = 39.26991

39.26991 + 150 = 189.26991

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.

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:

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:

Mary should be correct because -0 doesn't exist.

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: 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 :)
