Solve Equations with Constants on Both Sides

In all the equations we have solved so far, all the variable terms were on only one side of the equation with the constants on the other side. This does not happen all the time—so now we will learn to solve equations in which the variable terms, or constant terms, or both are on both sides of the equation.

Our strategy will involve choosing one side of the equation to be the “variable side”, and the other side of the equation to be the “constant side.” Then, we will use the Subtraction and Addition Properties of Equality to get all the variable terms together on one side of the equation and the constant terms together on the other side.

By doing this, we will transform the equation that began with variables and constants on both sides into the form  We already know how to solve equations of this form by using the Division or Multiplication Properties of Equality.

Solve: 

Solution

In this equation, the variable is found only on the left side. It makes sense to call the left side the “variable” side. Therefore, the right side will be the “constant” side. We will write the labels above the equation to help us remember what goes where.



Since the left side is the “”, or variable side, the 8 is out of place. We must “undo” adding 8 by subtracting 8, and to keep the equality we must subtract 8 from both sides.

Use the Subtraction Property of Equality.Simplify.Now all the variables are on the left and the constant on the right.

The equation looks like those you learned to solve earlier.Use the Division Property of Equality.Simplify.Check:Let .

Solution

Notice, the variable is only on the left side of the equation, so we will call this side the “variable” side, and the right side will be the “constant” side. Since the left side is the “variable” side, the 9 is out of place. It is subtracted from the , so to “undo” subtraction, add 9 to both sides. Remember, whatever you do to the left, you must do to the right.

Perimeter = 6s + 9 units

Step-by-step explanation:

Perimeter = 2s + 4 + 4s + 2 + 3

                = 2s + 4s + 4 +  2 + 3

                = 6s + 9 units

Answer:

(a) If r is any rational number and s is any irrational number, then r/s is rational

(b) The statement is false when r is 0

Step-by-step explanation:

Given

[tex]r \to[/tex] rational number

[tex]s \to[/tex] irrational number

[tex]\frac{r}{s} \to[/tex] irrational number

Solving (a): The negation

To get the negation of a statement, we only need to negate the end result

In other words, the number type of r and s will remain the same, but r/s will be negated.

So, the negation is:

[tex]r \to[/tex] rational number

[tex]s \to[/tex] irrational number

[tex]\frac{r}{s} \to[/tex] rational number

Solving (b): When r/s is irrational is false

Given that:

[tex]\frac{r}{s} \to[/tex] irrational number

Set r to 0

So:

[tex]\frac{r}{s} = \frac{0}{s}[/tex]

[tex]\frac{r}{s} = 0[/tex] -- rational

Hence, the statement is false when r is 0

Answer:

1 1/2 miles

Step-by-step explanation:

Amy is going on a 4 1 /4 miles hike. She has already hiked 2 3 /4 ​ miles. How many more miles does she have left?

We solve the above question using the operation of Subtraction

The number of miles she has left is calculated by:

Total number of miles she must hike - Number of miles she has hiked

Total number of miles she must hike

= 4 1/4 miles

Number of miles she has hiked = 2 3/4 miles

Therefore:

The number of miles she has left to hike is = 4 1/4 miles - 2 3/4 miles

Lowest Common Denominator = 4

4 - 2 + ( 1/4 - 3/4)

2 + (1 - 3/4)

2 + -2/4

1 2/4

= 1 1/2 miles

26 math problems

16 science problems

===============================================

Work Shown:

m = number of math problems

s = number of science problems

Since "you have 10 more math problems than science problems", we can say m = s+10

Also, we can say m+s = 42 because there are 42 problems total.

Replace m with s+10, which is the substitution rule, and solve for s like so

m+s = 42

s+10+s = 42

2s+10 = 42

2s = 42-10

2s = 32

s = 32/2

s = 16

You have 16 science problems

m = s+10

m = 16+10

m = 26

and you have 26 math problems

To check this, we would say m+s = 26+16 = 42 which confirms the answer.

Answer:

6825 in

Step-by-step explanation:

Since the shape is a composite figure, we need to break it up into 2 shapes!

Rectangle and a triangular prism

Solving for Rectangle...

Volume = Length · Width · Height

Volume = 30 · 13 · 13

Volume = 5070 in

Solving for Triangular Prism

Volume = Length · Width · Height / 2

Volume = 30 · 9 · 13 / 2

Volume = 3510/2

Volume = 1755 in

Finally, add the volumes!

5070 + 1755 = 6825 in

perimeter is 35.6 area is 108

Step-by-step explanation:

it helps to draw a picture. first the perimeter of the rectangle is 4x2 +12=20 we wont be needing one of the twelves because it is connected to the triangle the area or the rectangle is 12x4=48. now for the triangle. we will need the Pythagorean theorem to find the sides first split the base in half 12/2=6 now we use the height and the base 6^{2} +5x^{2} =6

2

+5x

2

= 61 the square root of 61 is about 7.8 the perimeter is 7.8+7.8 +12 but we wont need the base because it is attached to the rectangle =15.6 the area of the triangle is like half a square Base times height though 12x5=60

the whole perimeter if 15.6+20=35.6 the area is 60+48=108

Answer:

$563.89:  total cost of the banquet

Step-by-step explanation:

Here we can to find the total cost, including tax and tip, by adding 9.25% and 18% together first.  We obtain 17.25%, which translates into the decimal fraction 0.1725 and results in the amount added to the original cost, $480.93.  The result is added to $480.93:  

1.0000($480.93) + 0.1725($480.93)  =  $563.89

A shortcut would be to find the total cost, including the original $480.93 and the additional 17.25%, by multiplying $480.93 by 1.1725:

1.1725($480.93) = $563.89:  total cost of the banquet

I don't find this in the list of options. did you type everything correctly?

Answer:

D

Step-by-step explanation:

To check this answer, you could obviously graph the points, but without graphing, you can tell the line would be straight because each x value is multiplied by the same number to get the corresponding y value.

3 x 5 = 15, 4 x 5 = 20, etc. This shows linear growth. If each x value were multiplied by twice itself (3 x 6, 4 x 8, and so on), you wouldn't have a straight line because the number that x is multiplied by changes depending on the value of x.

Answer:

The answer is "20-gon"

Step-by-step explanation:

As the number of the sides increases the perimeters of the regular polygon go more closer to the circumference of the large circle. therefore the circumference of a circle is best moduled by the perimeter of the zo-gon as it has the maximum sides (z0) compared to hexagon (6), 15 gon(15), and Dodecagon(12).

Answer:

A, C, E, F

Step-by-step explanation:

...............

C= 0.25x + 200 represents the rental cost of renting a car with rental fees of $200 and additional fees per 'x' mile as $ 0.25.

" Equation is defined as the representation the relation of variables with the sign of equality."

According to the question,

'x' represents the number of miles

'C' represents the rental cost

Rental fees of a car = $200

Additional fees per 'x' miles = $0.25

As per the condition given we have,

C = 0.25x +200

The given model states that total cost of the car is equals to the rental fees of the car is $200 and the additional fees per 'x' miles is $0.25.

Hence, Option(C), Option(E) and Option(F) are the correct answer.
