For what value of x does 2x-4/x+7 = 1/3?
A. 33/5
B. 2
C. 19/5
D. -7
Answer:
A i think
Step-by-step explanation:
1 Multiply both sides by 3x3x.
6{x}^{2}-12+21x=x6x
2
−12+21x=x
2 Move all terms to one side.
6{x}^{2}-12+21x-x=06x
2
−12+21x−x=0
3 Simplify 6{x}^{2}-12+21x-x6x
2
−12+21x−x to 6{x}^{2}-12+20x6x
2
−12+20x.
6{x}^{2}-12+20x=06x
2
−12+20x=0

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]

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.

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

Austin is building a miniature replica of the empire state building. the actual empire state building is 1,423 feet tall and 6,000 feet wide. if Astin's replica has a width of 60 centimeters, what is the hight of his empire state building replica rounded to the nearest centimeter?
60/6000 = x/1423
100/1 = 1423/x
100x = 1423
x = 14.23 --> About 14 cm

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
