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?
=====================================================
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

Answer: C
Step-by-step explanation:
5.7+11.8=17.5+0.08=17.58=. 18
Answer: 18
Step-by-step explanation: If you add all 3 numbers, you will get 17.58
Now to round it to the nearest whole numbers, look at the 2 whole numbers nearest to it. 17 or 18. Anything .49 or lower will round down. Anything .50 or higher will round up. So if it was 17.49 it would round round to 17. This is 17.58 so it will round up to 18.
Determine which integer will make the inequality 18 > 3x + 9 true.

Ben earns $940 for working 80 hours on his job
a. Write an equation to represent the amount of pay Ben will earn for any number of hours worked.
b. Use your equation to determine how many hours Ben worked if he earned a total of $411.25
Answer:
5.1 or 5.140625 (The equation would be 411.25/80=5.140625)
Step-by-step explanation:
80x=940
x=11.75
80x=411.25
x=5.140625
The equation would be
411.25/80=hours
hours =5.140625

The following angles are supplementary to each other.
m∠A = (3x + 21)° and m∠B = (6x − 21)°
Determine x.
10
20
36
60
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.

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?
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

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?
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

Step-by-step explanation:
This is a simple unit-rate proportion. We're trying to find the rate of 1 gallon to unknown money. To get 1 gallon, we have to divide it by 13, because that's the total gallons we start with.
13 = 24.57

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