Answers

Answer:

13x8=104 13+8=21

Step-by-step explanation:

Hope this helps!

13•8=104. 13+8=21. To be honest I just used process of elimination. You can do this by listing the factors of 104, which are 1 & 104, 2 &52, 4 & 26, and 8 & 13. Then you add the pairs. 104+1=105, 105 does not equal 21. 52+2=54, 54 does not equal 21. 26+4=30, 30 does not equal 21. This means the answer has to be 13 & 8 because 13+8=21, and 21 is equal to 21.

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

really appreciate it lol

GCF is greatest common factor. LCF is least common answer. A number to be multiplied is a factor. A prime number’s only factors are one and itself (you can only divide it by one or itself to get a whole number). A composite number has more than two factors (one and itself). For example 7 is prime because you can only divide it by one and seven to get a whole number. On the other hand, 8 is composite because it can be divided by 8, 1, 4, and 2.

The following angles are supplementary to each other.

m∠A = (3x + 21)° and m∠B = (6x − 21)°

Determine x.

20

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.

Range

Step-by-step explanation:

By finding the mean (average) of the ages, it doesn't really describe the ages. The range of the boys is 10-14, and describes how old they are much better than saying that the average age of boys is 12.

The range of their ages should be used. Using the range gives more details on their ages than finding the average of all the ages does.

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

The system has no solutions.
1. 4x=-29+2y

2. 2y=-16+4x (rearranged equation)
Plug the rearranged equation into the first one.
