Answer:
Weight of Train A = A = 237 tons
Weight of Train B = B = 96 tons
Step-by-step explanation:
Two trains train a and be weigh a total of 333 tons. Train A is heavier than train B.The difference of their weight is 141 tons… What is the weight of each train??
Let us represent:
Weight of Train A = A
Weight of Train B = B
Our system of Equations is given as:
A + B = 333 tons..... Equation 1
A - B = 141 tons....... Equation 2
We solve using Elimination method
We Add Equation 1 and 2 together to Eliminate B
Hence:
2A = 474 tons
A = 474 tons/2
A = 237 tons
Solving for B using Equation 1
A + B = 333 tons..... Equation 1
237 tons + B = 333 tons
B = 333 tons - 237 tons
B = 96 tons
Therefore:
Weight of Train A = A = 237 tons
Weight of Train B = B = 96 tons

Which of the following isolates r correctly?
4r - 6 = 2(n + 3)
Answer:
r = 1/2n + 3
Step-by-step explanation:
Are there answer choices to choose from?
This is how you would isolate the r:
4r = 2n + 6 + 6 so 4r = 2n + 12
Solve for r by dividing both sides by 4 so r = 1/2n + 3
Answer:
-2=2n+6
2n=2-6
2n=-4
n=-2

Answer:
x=29.4
Step-by-step explanation:
To help find the sides of a triangle, I use SOHCAHTOA.
SOH - CAH - TOA
S=O/H ([tex]Sine=\frac{opposite}{hypotenuse}[/tex] )
C=A/H ([tex]Cosine=\frac{adjacent}{hypotenuse}[/tex] )
T=O/A ([tex]Tangent =\frac{opposite}{adjacent}[/tex] )
Let's find x first. We know 2 parts of the triangle: the adjacent leg, and the angle that is opposite of that.
So it would be tangent (tan).
opposite = 17
adjacent = 30°
Plug these numbers into the calculator and you should get your answer.
[tex]\frac{17}{tan(30)} = 29.44486372...[/tex]
x=29.4
Try to do y on your own and let me know if you have any questions!
Also correct me if I'm wrong on anything.
Hope this information helps!

Answer:
The area of triangle VZX is 210 cm^2
Step-by-step explanation:
Here, we want to get the measure of the area of triangle VZX
From the given diagram, we have two explicit triangles making up triangle VWX
These are triangles VWZ and VZX
By adding the areas of both triangles, we can get the area of VWX
Mathematically, the area of VZX is the difference between the area of VWX and VZW
To get the area of VZW, we can use the formula for the area of a triangle
We have this as 1/2 * base * height
base = 35 cm and height = 28 cm
The area of VWZ is 1/2 * 35 * 28 = 490 cm^2
The area of triangle VZX is thus;
700 cm^2 - 490 cm^2 = 210 cm^2
about what percent of gyms in shanesville have fewer than 56 gym members
Answer:
25%
Step-by-step explanation:
About 25% of gyms in Shanesville have fewer than 56 gym members.
The correct answer is option (2).
What is interquartile range?"Interquartile range = Q3 - Q1"
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
For this example,
Q1 = 56
Q2 (median) = 64
Q3 = 70
So, the interquartile range is,
⇒ 70 - 56 = 14
Let 'x' be the number of gyms in Shanesville have fewer than 56 gym members.
so, the percent of gyms in Shanesville have fewer than 56 gym members would be,
⇒ 14 / x = 56
⇒ x = 14 / 56
⇒ x = 1/4
⇒ x = 0.25
The percentage of 'x' would be,
⇒ 100 × 0.25 = 25 %
Therefore, about 25% of gyms in Shanesville have fewer than 56 gym members.
The correct answer is option (2).

A tank has 120 gallons of water and is being drained at a rate of 12 gallon each second. Another tank has 100 gallons of water and is being drained at a rate of 14 gallon each second. Which equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water? Multiple choice question.
The equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120-1/2x = 100-1/4x
What is meant by equation?There are many different ways to define an equation. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
Various kinds of equations: Algebraic math equations include the following.
Equation with Lines;
More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.
Equation in QuadratureThis equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic FormulaA third-order equation is this one. At least one of the variables in cubic equations needs to be increased to exponent 2
Given ,
tank 1 = 120 - 1/2x
tank 2 =100 - 1/4x
Therefore 120-1/2x = 100-1/4x
So we can conclude that the equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120-1/2x = 100-1/4x
The complete question is: A tank has 120 gallons of water and is being drained at a rate of 12 gallon each second. Another tank has 100 gallons of water and is being drained at a rate of 14 gallon each second. Which equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water? Multiple choice question.
120x + 1/2 = 100x + 1/4
120 + 1/2x = 100 + 1/4x
120x - 1/2 = 100x - 1/4
120 - 1/2x = 100 - 1/4x

Plssss help———What is an exponent and how do you solve it? 4-5 sentences :)
Answer:
[tex] {5 }^{2} [/tex]
that is an exponent
Step-by-step explanation:
an exponent is a number at the top right corner of a bigger (physichally) number. Exponents can also be said "to the power". for example 5 to the second power, or power of 2. this just means that instead of multiplying 5 x2 you are multiply 5 x itself the amount of times the exponent tells tou for example 5 x 5 (since my exponent is 2) is 25. so 5 to the second power is 25. and if it said 5 to the power of rhree i would have done 5x5x5 =125
