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

I could use some help on my homework please. Don't really understand and would like the steps in solving
Answers
x= -29+2y/4
-4(-29+2y/4)+2y=-16
+116-8y/4 +2y=-18
1. 4x=-29+2y
-4x+2y=-16 (rearrange this equation to find 2y)
2. 2y=-16+4x (rearranged equation)
Plug the rearranged equation into the first one.
3. 4x=-29+(-16+4x) (new equation)
Now solve for X
4. Once you solve the equation you’ll find 0=-45 which means there’s no solution
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
=====================================================
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

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

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.

Answers
It would be that because if Ruben runs 16 miles over a 4-day period, it would mean that he ran 4 miles a day (16/4). And if Claire runs 12 miles over a 3-day period, it would mean that she also ran 4 mi per day (12/3)

Determine x.

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.
