Andy and Nick went to the amusement park. They each bought a sandwich, and Nick got a small drink. Andy had a $10 gift certificate to put toward the cost, and Nick paid the rest, which came to $44.50. A ticket costs $20.00, and a sandwich costs $6.50. How much does a drink cost at the amusement park?

Answers

Answer:

$1.25

Step-by-step explanation:

To do this problem, you need to note that they bought two of almost everything. You are also working backwards at first to get how much they spent total and then taking away the expenses.

The first step is finding how much money they spent total, and you can do this by adding the gift certificate to the price:

44.5 + 10 = $55.50

Now, you see that they each bought a ticket for $20 EACH. There were two tickets (one for Andy, one for Nick). So multiply 20 by 2 and subtract that from your total cost.

$55.50 - (2 * $20) =

$55.50 - $40 =

$15.5

They bought a total of TWO sandwiches at 6.50 each. So repeat these steps, subtracting from the number above (underlined)

$15.50 - ($6.50 * 2) =

$15.50 - $13 =

$2.5

They bought two drinks that totaled to be $2.50.

To find the cost of ONE drink, divide this number by 2:
$2.50/2 =

$1.25

Answer:

A drink costs $1.5 at the amusement park

Step-by-step explanation:

44.50 + 10 = 54.5

2 people         1 ticket = $20             1 sandwich = $6.5

20 × 2 = 40

6.5 × 2 = 13

40 + 13 = 53

54.5 - 53 =  1.5

The following angles are supplementary to each other.

m∠A = (3x + 21)° and m∠B = (6x − 21)°

Determine x.

10
20
36
60

Answers

Answer: X=20

Step-by-step explanation: Supplementary angles, by definition, add up to 180.

(3x + 21) + (6x - 21) = 180

3x + 6x + 21 - 21 = 180

9x = 180

9x/9 = 180/9

x = 20

x = 20 . Option B is correct.

What are supplementary angles?

Two angles are supplementary to each other if their sum is equal to 180°.

Given,

          ∠A = (3x + 21)°

And  ∠B = (6x − 21)°

Also, ∠A and ∠B are supplementary angles.

Therefore,    ∠A + ∠B = 180°

           (3x + 21)° + (6x − 21)° = 180°

                (9x + 0)° = 180°

Hence, x = 20.

1. Do the product rule:
Since the base of both numbers are the same, keep the base. In this case, it’s 2. Next add the exponents together. 3 + 2 = 5.
So the simplified one would be 2^5 (two to the fifth power)

2. Multiply 2 by itself five times; 2 • 2 • 2 • 2 • 2 = 64
So evaluated (calculated) the answer would be 64.

Use the Distributive Property to solve the equation 25−(3x+5)=2(x+8)+x.

Answers

As we use the distributive property, we’ll get the answer X = 2/3

Answer:

x = 2/3 or x = 0.666...

Step-by-step explanation:

First distribute -1 into 3x and positive 5. giving you -3x - 5. on the opposite side distribute 2 x and 8, giving you 2x+ 16. now Combine Like Terms. on the left side combine 25 and -5. on the right side combine 2x and x. the equation should look like this now 20 -3x = 3x + 16. now solve for x. to do that add 3x to both sides to remove -3x on the left side. now subtract 16 from both sides. giving you 4=6x. divide by six and x =2/3 or x= 0.666.....

A local hamburger shop sold a combined total of 512 hamburgers and cheeseburgers on Saturday. There were 62 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Saturday?

Answers

Number of hamburgers sold on Saturday is 225

Finding Unknown quantity using Linear equation

To find an unknown quantity, first make a linear equation according to the relation given in the problem and solve obtained equations for the required quantity.

Here we have,

Total number of hamburgers and cheeseburgers sold on Saturday = 512

The Number of cheeseburgers is 62 more than that of hamburgers  

Let x and y be the number of cheeseburgers and hamburgers

As we know number of cheeseburgers is 62 more than that of hamburgers  

=> x = y + 62 —-(1)

And total number of burgers sold = 512

=> x + y = 512 —-(2)

Substitute (1) in (2)

=> y + 62 + y= 512

=> 2y = 512 - 62

=> 2y = 450

=>  y = 450/2

=>  y = 225  

Number of hamburgers sold on Saturday is 225

A truck driver drove 150 miles in 3 hours. At that rate, how long will it take the drive to travel 500 miles?

I’m bad at math and confused. Help?

Answers

Answer:   10 hours

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

Explanation:

We'll use the values in the first sentence to find the rate or speed.

distance = rate*time

rate = distance/time

rate = (150 miles)/(3 hours)

rate = 50 miles per hour

Now we can determine the time needed to travel 500 miles

distance = rate*time

time = distance/rate

time = (500 miles)/(50 mph)

time = 10 hours

Answer: 10 hours

Step-by-step explanation:

    We can set up a proportion to solve. Let x be equal to the number of hours it takes to drive 500 miles.

[tex]\displaystyle \frac{150\;miles}{3\;hours} =\frac{500\;miles}{x\;hours}[/tex]

    Now, we will cross-multiply.

150 * x = 500 * 3

150x = 1,500

    Lastly, we will divide both sides of the equation by 150 to isolate the variable

x = 10 hours
