1/3(2x-3/7)+1/6x=4/7 find x
If the equation is 1/3(2x - 3/7)+(1/6)x = 4/7 , then the value of x is 3/7.
The given equation is
1/3(2x - 3/7)+(1/6)x = 4/7
First we have to apply the distributive property of subtraction in the equation
1/3(2x - 3/7)+(1/6)x = 4/7
(3/2)x - 1/7 + (1/6)x = 4/7
Here we have to rearrange the terms and group the like terms
Move the 1/7 to right hand side of the equation
(3/2)x + (1/6)x = (4/7)+(1/7)
Addition of like terms
(5/3)x = 5/7
Move the 5/3 to the right hand side of the equation
x = 5/7 ÷ 5/3
x = 5/7 × 3/5
x = 3/7
Hence, if the equation is 1/3(2x - 3/7)+(1/6)x = 4/7 , then the value of x is 3/7

Graph the line -3 with slope (-4,-2) passing through the point
The linear equation of the line that passes through point (-4,-2) and has a slope of -3 is y = -3x - 14.
What is the graph of the line with the given slope and point?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the data in the question;
Point ( -4, -2 )
x = -4y = -2Slope m = -3First we calculate the y-intercept 'b' using the equation of line formula.
y = mx + b
Plug in point ( -4, -2 ) and slope -3.
-2 = -3(-4) + b
-2 = 12 + b
b = -2 - 12
b = -14
Now that we have the values of slope m and y-intercept b, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = -3(x) + ( -14 )
y = -3x - 14
Therefore, the equation of the line is y = -3x - 14.

Mayerlin is deciding between two different movie streaming sites to subscribe to. Plan A costs $34 per month plus $2 per movie watched. Plan B costs $8 per month plus $3 per movie watched. Let AA represent the monthly cost of Plan A if Mayerlin watches xx per month, and let BB represent the monthly cost of Plan B if Mayerlin watches xx movies per month. Write an equation for each situation, in terms of x,x, and determine the number of monthly movies watched, x,x, that would make the two plans have an equal monthly cost.
Considering the definition of an equation and the way to solve it, the number of monthly movies watched that would make the two plans have an equal monthly cost is 26.
Definition of equationAn equation is an algebraic equality in which there are unknowns with unknown value. The unknown represents the number, if any, that makes the equality true. This unknown number is the solution of the equation.
This is, the solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Number of monthly movies watchedBeing "x" the number of monthly movies watched, you know that:
Plan A costs $34 per month plus $2 per movie watched. → A= 34 + 2xPlan B costs $8 per month plus $3 per movie watched. → B= 8 + 3xIf the two plans have an equal monthly cost, the equation in this case is:
A= B
34 + 2x= 8 + 3x
Solving:
34 - 8= 3x - 2x
26= x
Finally, 26 monthly movies watched would make the two plans have an equal monthly cost.

i earn an annual salary of $30,572 and my commission is 5% on all sales. How much must my sales be if i want my annual salary to be $31,836?
If you want to make an annual salary of $31,836, then your sales must be $25,280
How much must my sales be to get the desired salary?
Ok, so you want to earn a total of $31,836, and he has a fixed salary of $30,572, so the missing amount is:
$31,836 - $30,572 = $1,264
Now, we know that you make a commission of the 5% of what you sell, so if X is what you sell, then to make the desired salary X must be:

The perimeter Perimeter is given by the sum of the sides as follows:
P = z + 5 + z + 5 + z + z
Substituting P=26 and adding like terms,
26 = 10 + 4z
Subtracting -10 to both sides:
26 - 10 = 10 - 10 + 4z
Simplifying:
16 = 4z
Dividing both sides by 4:
16/4 = z
Switching and simplifying:
z = 4
So,
Equation: 26 = 10 + 4z

A silo containing 800 gallons of grain is emptied at a constant rate of 400 gallons every 1
hour.
Enter an equation in the form y = mx + b that represents the amount of grain y, in gallons,
remaining in the silo after x hours.
The equation of the line is y = -400x + 800
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the equation that represents the amount of grain?The given parameters are
Initial number of gallon, c = 800
Constant rate, m = -400 gallons per hour
This means that
Slope = -400
y-intercept = 800
A linear equation is represented as
y = slope * x + y-intercept
i.e.
y = mx + c
So, we have
y = -400x + 800

By using subtraction, we get that, the total yardage for the drive was that they gained 7 yards.
We are given that:
On a drive,
A football team first gains = 3 yards.
Then it lost = 11 yards.
Then it again gained = 15 yards.
We need to find its total yardage.
For this, we will subtract the yards lost from the yards gained by the team.
So, we get that:
total yardage = 3 + 15 - 11
total yardage = 18 - 11
total yardage = 7 yards.

Answer:
To one decimal place, x = 7.7 cm
Step-by-step explanation:
Let y equal BD.
Since AD is a bisector of angle BAC, angle DAB is 17°.
tan(17°) = y/21, so y = 21 tan(17°)
tan(34°) = (x + 21 tan(17°))/21
21 tan(34°) = x + 21 tan(17°)
x = 21(tan(34°) - tan(17°)) = 7.7 cm

there is 360° in a full circle or a repeating angle (aka the scissors)

Angles on a straight line sum to 180°.
⇒ m∠1 + m∠2 = 180°
⇒ 143° + m∠2 = 180°
⇒ m∠2 = 37°
Vertical Angle Theorem

The eastbound train travels 18 miles per hour faster than the westbound train. After 2.5 hours, they are 280 miles apart. At what speeds are the two trains traveling?
Answer: The eastbound train is traveling at 65mph while the westbound train travels at 47mph.
Step-by-step explanation:
You would use x as the variable for the speed of the westbound train. The eastbound train would be 18+x. your equation would be 2.5(18+x+x)=280
You would find that x=47 for the westbound train. You would then add 18 to get the speed of the eastbound train which would be 65.
