An automobile manufacturer is preparing a shipment of cars and trucks on a cargo ship that can carry 21,600 Tons. The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each. For a different shipment, cars are loaded first, and then trucks are loaded afterwards. Write an equation you could enter into a calculator or a spreadsheet tool to find the number of trucks that can be shipped if the number of cars is known. Let x=number of cars (input) and Let y=number of trucks (output)
Answer:
Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]
Step-by-step explanation:
A cargo ship can carry 21,600 Tons.
Let x denotes number of cars and y denotes number of trucks.
The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each.
Therefore,
[tex]3.6x+7.5y=21,600[/tex]
Now write y in terms of x.
[tex]7.5y=21,600-3.6x\\y=\frac{21,600-3.6x}{7.5}[/tex]
Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]

A chemistry teacher has a flask of a 45% acidic solution and another bottle of 28% acidic solution.
How much would he need to use of each container to arrive at a final solution that is 100 mL of a 33.95% solution?
Answer:
35 ml of 28% acidic solution and 65ml of 45% acidic solution is to be used
Step-by-step explanation:
Let the number of ml of the 45% solution be x while that of the 28% solution be y
Mathematically;
x + y = 100 ••••••(i)
Furthermore
45% of x + 28% of y = 33.95% of 100
0.45x + 0.28y = 33.95 ••••••(ii)
From i,
x = 100-y
put this into ii
0.45(100-y) + 0.28y = 33.95
45 - 0.45y + 0.28y = 33.95
45 - 33.95 = 0.45y - 0.28y
11.05 = 0.17y
y = 11.05/0.17
y = 65
Recall
x = 100 - y
x = 100 - 65
x = 35 ml
Is the ordered pair (–8, –7) a solution to the equation 3x + 10 = 2y? Show your work.
Answer:
yes
Step-by-step explanation:
Substitute x = - 8 and y = - 7 into the equation
If both sides are equal then (- 8, - 7) is a solution
left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14
right side = 2y = 2(- 7) = - 14
Since both sides are equal then (- 8, - 7) is a solution to the equation

Plz help with graph polynomial
Answer:
(x + 1 ) is a factor
Step-by-step explanation:
Given a polynomial with roots x = a, x = b , then the corresponding factors are
(x - a) and (x - b)
From the graph
The roots are x = - 1 and x = 4 , thus factors are
(x - (- 1)) and (x - 4) , that is
(x + 1) and (x - 4)
(x + 1) is the required factor

24 is equal to 25% of a number n. Write and solve an equation to find n. Write the percent as a Decimal. PLEASE HELP ME
Answer:
Equation: 25% x n = 24
n = 96
Step-by-step explanation:
Because of means to multiply 25% OF n would mean you multiply to solve for n you would do the opposite which is dividing. 25% is the same as .25 so you would do...
24 ÷ .25 = 96
So 96 = n

4 ( 11 + 7 ) = ? + 28
Let the missing number be x .
Then :-
[tex]4(11 + 7) = x + 28[/tex]
[tex]4 \times 18 = x + 28[/tex]
[tex]72 = x + 28[/tex]
[tex]x + 28 = 72[/tex]
[tex]x = 72 - 28[/tex]
[tex]x = 44[/tex]
Therefore , 4 ( 11 + 7 ) = 44 + 28 .

On a coordinate plane, a line is drawn between point (x 2, y 2) and (x 1, y 1). Which equation would find the distance between the two points show on the coordinate plane? d = StartRoot (x 2 + x 1) squared + (y 2 + y 1) squared EndRoot d = StartRoot (x 2 minus x 1) squared minus (y 2 minus y 1) squared EndRoot d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot
Answer:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
Given: A line is drawn between points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]
To find: distance between the two points
Solution:
A coordinate plane is a two-dimensional plane formed by the intersection of a y-axis and x-axis. x-axis and y-axis are perpendicular lines that intersect each other at the origin.
Let d denotes distance between the two points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]
Use the formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The distance between the two points show on the coordinate plane is D = √[(x₂-x₁)²+(y₂-y₁)²]. Therefore, the correct answer is option C.
The given coordinate points are (x₁, y₁) and (x₂, y₂).
The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.
On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is
Distance = √[(x₂-x₁)²+(y₂-y₁)²].
Therefore, the correct answer is option C.

g(5a-2)+3g(2a) if g(x)=x^2-5x+8
The solution for the equation will be 37 a² - 55 a + 30
What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
g ( x ) = x² - 5 x + 8
To solve for g ( 5 a - 2 ) + 3 g ( 2 a ) , substitute for the value of x
Therefore ,
g ( 5 a - 2 ) = ( 5 a - 2 )² - 5 ( 5 a - 2 ) + 8
= ( 25 a² + 4 - 20 a ) - 25 a + 10 + 8
= 25 a² - 45 a + 22
3 g ( 2 a ) = 3 [ (2 a )² - 10 a + 8 ]
= 3 [ 4 a² - 10 a + 8 ]
= 12 a² - 10 a + 8
And , g ( 5 a - 2 ) + 3 g ( 2 a ) = 25 a² - 45 a + 22 + ( 12 a² - 10 a + 8 )
= 37 a² - 55 a + 30
Hence , the value of the equation will be 37 a² - 55 a + 30
