On tuesday a local hamburger shop sold a combined total of 504 hamburgers and cheeseburgers. The number of cheeseburgers sold was 3 times the number of hamburgers sold. How many hamburgers were sold on tuesday?
Answer:
126
Step-by-step explanation:
Let the no. of hamburger be n
Then the no. of cheeseburgers = 3n
3n + n = 504
4n = 504
n = 504 / 4
n = 126

Write a system of linear equations for the problem and solve the system using an augmented matrix and your calculator.
Mike works a total of 59hr per week at his two jobs. He makes $8 per hour at job A and $9 per hour at job B. If his total pay for one week is $494 before taxes, then how many hours does he work at each job?
Answer: he works 37 hours in job A, and 22 hours in job B.
Step-by-step explanation:
Let's define the variables:
A = number of hours that he works at Job A
B = number of hours that he works at Job B.
We know that he works a total of 59hr per week, then we have:
A + B = 59
And we also know that he makes $494 in one week, then we have the equation:
A*$8 + B*$9 = $494.
Then we have the system of equations:
A + B = 59
A*$8 + B*$9 = $494
To solve this with an augmented matrix, we need to turn these equations into a matrix, where we only write the coefficients as follows:
[tex]\left[\begin{array}{cccc}1&1&I&59\\8&9&I&494\end{array}\right][/tex]
(The I's should represent a line for the augmented matrix, that line separates the values of the coefficients to the right value of each equation)
The first column represents the A coefficients, the second column represents the B coefficients.
To solve this, we want to get something of the form:
[tex]\left[\begin{array}{cccc}1&0&I&x\\0&1&I&y\end{array}\right][/tex]
Where x and y are our solutions.
To do it we can just do: Column 2 - 8*column 1, this will get us to:
[tex]\left[\begin{array}{cccc}1&1&I&59\\8 - 8*1&9 - 8*1&I&494 - 8*59\end{array}\right][/tex]
=
[tex]\left[\begin{array}{cccc}1&1&I&59\\0&1&I&22\end{array}\right][/tex]
Now we can do: Column1 - column2, to get
[tex]\left[\begin{array}{cccc}1 - 0&1 - 1&I&59 - 22\\0&1&I&22\end{array}\right][/tex]
[tex]\left[\begin{array}{cccc}1&0&I&37\\0&1&I&22\end{array}\right][/tex]
Then the solutions are:
1*A =37
1*B = 22
This means that he works 37 hours in job A, and 22 hours in job B.

find the sum of of LCM and GCF of 15, 35, 56
Answer:
LCM sum: 3
GCF sum: 3
3 + 3 = 6
Step-by-step explanation:
Here I listed all the factors of each number:
15: 1, 3, 5, 15
35: 1, 5, 7, 35
56: 1, 2, 4, 7, 8, 14, 28, 56
As you can see, the LCM of these numbers is 1, since none of the other factors relate to all of the number's factors. This is also the only factor that all three of these numbers share.
1 + 1 + 1 = 3
The GCF of each of the numbers is also 1.
1 + 1 + 1 = 3
Hope this helps! :D

Katie is planting a garden for her science fair project she needs 2/3 of a cup of soil to go in a different parts how many cups of soil does she need in total
Katie requires 16/3 cups of the soil for planting a garden for her science fair.
How to calculate the total amount?Algebra is a mathematical technique for calculating unknown values.
Variables represent unknown parameters in an equation and are usually categorized by a letter of the alphabet. The value of the variable is determined by isolating it.Now, for the stated question;
Katie has been planting a garden for her science fair project. She requires 2/3 of a cup of soil for each of the eight pots.
To calculate the total amount of soil required, multiply the amount required for one pot by the number of total pots.
Total soil = (2/3)×8
Total soil = (2×8)/3
Total soil = 16/3
Therefore, the total amount of the soil requires for the gardening in science fair is 16/3 cups.

Find the value of the variable in the isosceles trapezoid.
The value of the variable in the isosceles trapezoid is 24.
Calculation of the value of the variable:Since the measure of one angle should be 63 degrees
And, there is the equation 2x + 15 degrees
So for determining the value of x here we have to equate the equation
So,
2x + 15 = 63
2x = 63 - 15
2x = 48
x = 24
Therefore, The value of the variable in the isosceles trapezoid is 24.

The gas tank on the back of a tanker truck can be equated to a cylinder with a diameter of 8 feet and a length of 19 feet. A gallon of gas is approximately 231 cubic inches. The density of the gasoline is .0262 pounds per cubic inch. The driver has stopped at a local farm to fill a tank that has linear dimensions that are 2/3 the size of his tank. If the driver's tank was full and the farmer's tank was empty, what is the mass of the gasoline in each of the tanks after the smaller tank is full?
9514 1404 393
Answer:
driver's tank: 30,427 lbfarmer's tank: 12,811 lbStep-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr^2·h . . . radius r, height h
The radius of the driver's tank is half its diameter, so is (8 ft)/2 = 4 ft. Then the volume of that tank is ...
V = π(4 ft)^2·(19 ft) = 304π ft^3
Each cubic foot of gasoline has a mass of ...
(1728 in^3/ft^3)(0.0262 lb/in^3) = 45.2736 lb/ft^3
Then the total mass in the driver's full tank is ...
(304π ft^3)(45.2736 lb/ft^3) ≈ 43,238.3 lb
__
The farmer's tank is a scaled-down version of the driver's tank. It's volume will be scaled by the cube of the linear scale factor, so will be (2/3)^3 = 8/27 of the volume of the driver's tank.
The farmer's tank will hold a mass of (43,238.3 lb)(8/27) ≈ 12,811 lb.
The amount remaining in the driver's tank is 43,238 -12,811 = 30,427 lb.
5x-2y=-3 -2x-y=-6 método de reducción suma y resta con procedimiento y respuesta doy corona a quien me ayude en menos de media hora
Answer:
(1, 4)
Step-by-step explanation:
5x-2y=-3 -2x-y=-6 =>
5x-2y=-3
-2x-y=-6 Multiply all three terms by -2: 4x + 2y = 12
Then we have:
5x-2y=-3
4x + 2y = 12
---------------------
9x = 9 and so x = 1. Then, using -2x - y = -6, and substituting 1 for x:
-2(1) - y = -6, or
2 + y = 6, or
y = 4
Then the solution is (1, 4)
