Answer:
[tex] a = \dfrac{4 - bc}{c} [/tex]
Step-by-step explanation:
c = 4/(a - b)
Multiply both sides by a - b.
c(a - b) = 4
ac + bc = 4
ac = 4 - bc
a = (4 - bc)/c
[tex] a = \dfrac{4 - bc}{c} [/tex]

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

Anna is buying tomatoes and jalapenos to make salsa. Tomatoes cost $2.99 per pound and jalapenos cost $1.33 per pound. Anna spent $12.65 buying tomatoes and jalapenos. The relationship between pounds of tomatoes, t, pounds of jalapenos, j, and the total cost is represented by the equation 2.99t+1.33j=12.65. Write an equation that makes it easy to find the number of pounds of jalapenos if we know the number of pounds of tomatoes purchased.
Answers
The equation that makes it easy to find the number of pounds of jalapenos is j = (12.65 - 2.99t)/1.33.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Tomatoes cost $2.99 per pound and jalapenos cost $1.33 per pound. Anna spent $12.65 buying tomatoes and jalapenos.
2.99t + 1.33j = 12.65
Make the subject as j and solve the equation for j:
1.33j = 12.65 - 2.99t
j = (12.65 - 2.99t)/1.33
Thus, the equation that makes it easy to find the number of pounds of jalapenos is j = (12.65 - 2.99t)/1.33.

Find the midpoint AND length of each segment with the given endpoints. Round to the nearest tenth of necessary.
J(4,3) & K(2-3) L(-4,5) & N(5,-3)
Midpoint: Length: Midpoint: Length:
Answers
The midpoint and length of the points J(4,3) and K(2,-3) is calculated as (1,0) and 40.
The midpoint and length of the points L(-4,5) and N(5,-3) is calculated as (-12,1) and 145.
Given : The endpoints J(4,3) and K(2,-3) and L(-4,5) and N(5,-3)
We need to find the midpoint and length of these endpoints.
The formula for midpoint is x1+x22, y1+y22
From the first endpoints, x1=4 , y1=3 , x2=2 , y2=-3
4+22, 3-32 => (22,02) => (1,0)
So, the midpoint for the endpoints is (1,0)
The formula to find the length is (x2-x1)2+(y2-y1)2
From the first endpoints , the length becomes
(2-4)2+((-3)-3)2=> (-2)2+(-6)2 => 4+36 => 40
The formula for midpoint is x1+x22, y1+y22
From the first endpoints, x1=-4 , y1=5 , x2=5 , y2=-3
-4+52, 5-32 => (-12,22) => (-12,1)
So, the midpoint for the endpoints is (-12,1)
The formula to find the length is (x2-x1)2+(y2-y1)2
From the first endpoints , the length becomes
(5+4)2+((-3)-5)2=> (9)2+(-8)2 => 81+64 => 145
Hence, the midpoint and the length from the endpoints is calculated and determined.

Step-by-step explanation:
For High School A, let denote the number of students after years. Define analogously.
Since we start out at 850 students at High School A and it is growing by 35 students every year, we must have that .
Since we start out at 700 students at High School B and it is growing by 60 students every year, we must have that .
Setting the two equations equal to each other, we see that

Answers
The sum of the three values is 10.25 meters.
Here, we are given three measurements- 7.5m, 2.25m and 50cm
Since, we need to find the answer in meters, let us convert all the units to meters so that we can add them.
7.5 and 2.25 are already in meters so we do not need to covert them.
We only need to convert 50 centimeters.
As per mathematical conversions,
1 meter = 100 centimeters
This means that 50 centimeters will be,
100/2 centimeters = 1/2 meters
⇒ 50 centimeters = 0.5 meters
Now, we add all the given numbers,
= 7.5 + 2.25 + 0.5
= 9.75 + 0.5
= 10.25
