Answer:

V/3k = t

Step-by-step explanation:

Isolate the variable (t)

V = 3k/t

We have to get rid of 3 and k to isolate t

Since 3 and k are part of a fraction we can multiply it by their reciprocal

V = 3k/t × 1/3k

What we do to one side, we must do to the other

V × 1/3k = 3k/t × 1/3k

The reciprocals equals 1

V × 1/3k = t × 1

Any number or variable multiplied by 1 equals itself (applies to both sides of the equation)

V/3k = t

Answer:

Y = 7

Step-by-step explanation:

You would add 4 to both sides to cancel out the -4. That leaves y by itself equaling 7.

The solution of the equation y – 4 = 3 will be 7.

The solution of the equation means the value of the unknown or variable.

The equation is given below.

y – 4 = 3

Add 4 on both sides, we have

y – 4 + 4 = 3 + 4

            y = 7

Complete question :

A pair of $36 jeans were on sale at Jim's Jeans for 1/3 off. The same pair of jeans were $42 at David's Denims. The jeans were on sale for 2/3 off.

A.) which store had the better buy

B.) how much will you pay at the store that has the better buy

Answer:

A.)David's denim has the better buy

B.) $14

Step-by-step explanation:

Jim's Jean store :

Cost of Jean = $36

Discount = 1/3 off

Discounted cost = $36 - (1/3 * $36)

Discounted cost = $36 - $12 = $24

David's Denim:

Cost of Jean = $42

Discount = 2/3 off

Discounted cost = $42 - (2/3 * $42)

Discounted cost = $42 - $28 = $14

David's denim has the better buy with a discounted price lower than the discounted price at Jim's store.

Cost at store with the better buy is $14

It could be 443, try simplifying to the nearest hundreaths, hope this helps!

Answer:

so you are going to divide with  a calculator

19,067 divided by 43

equals 443.4186047 (simplify)

Answer is $14

Answer:

y = x + 5

Step-by-step explanation:

The standard form of the slope-intercept is

y = mx + b

where m is the slope

According to this question, the slope is 1 for the given equation

If two lines are parallel, they have equal slopes

So the slope of the line we are trying to get is 1

We can now use the point-slope form to get the equation of the second line

Mathematically, that will be

y-y1 = m(x-x1)

where m is slope and (x1,x2) are the points given

So therefore;

y-3 = 1( x - (-2))

y-3 = x + 2

y = x + 5

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Identify

We are given a right triangle. We can use PT to solve for the missing length a.

Step 2: Define

hypotenuse c = 15

leg b = 9

leg a = ?

Step 3: Find missing length a

Since we are not dealing with a quadrant triangle, we can disregard the negative root of the quadratic.

∴ a = 12 is our final answer.

Answer:

The standard deviation will be: 2.1        

Step-by-step explanation:

We know that standard deviation is basically the square root of variance.

Using the formula to calculate the standard deviation

[tex]s=\sqrt{s^2}[/tex]

As

so the standard deviation can be calculated as:

standard deviation [tex]=\sqrt{s^2}[/tex]

                                 [tex]=\sqrt{\left(4.4\right)^}[/tex]

                                  [tex]=2.1[/tex]

Therefore, the standard deviation will be: 2.1                      

Answer:

1) 3x = 2x + 50

3x - 2x = 50

X= 50

2)6x = 2x + 44

6x - 2x = 44

4x = 44

divide both sides by 4

X = 11

3)8x = 2x + 36

8x - 2x = 36

4x = 36

divide both sides by 4

X = 9

4) 4x = X + 18

4x - X = 18

3x = 18

divide both sides by 3

X= 6

5) 7x + 10 = 3x + 120

collect like terms

7x - 3x = 120 - 10

4x = 110

divide both sides by 4

X = 27.5

6) 20 + 2x = X + 56

collect like terms

2x - X = 56 - 20

X = 36

7) already done

8)12x + 12 = 3x + 84

collect like terms

12x - 3x = 84 - 12

9x = 72

divide both sides by 9

X = 8

9) 3 + 6x = 2x + 27

collect like terms

6x - 2x = 27 - 3

4x = 24

divide both sides by the coefficient of X (4)

X = 6

10) 8x + 2 = 72 + X

collect like terms

8x - X = 72 - 2

7x = 70

divide both sides by the coefficient of X (7)

X = 10

11) 2x + 20 = X + 60

collect like terms

2x - X = 60 - 20

X = 40

12). 4x + 1 = 25 + 2x

collect like terms

4x - 2x = 25 - 1

2x = 24

divide both sides by the coefficient of X (2)

X = 12

Answer:

T=12500-0.25y

Step-by-step explanation:

Step one:

given data

The value of the car is $12500.

let the value of the previous year be T

let the number of years be y

25% will be 0.25----this is equivalent to the gradient

The expression for the change in price can be represented linearly using the equation of a straight line,

y=mx+c

but since the price is reducing the expression becomes

y=-mx+c

Now, in this situation the expression for the cost after y years is

T=-(0.25y)+12500

rearrange

T=12500-0.25y

The expression is T=12500-0.25y

Answer:

its B and D

Step-by-step explanation:

cause 1.5 times 1.5 times 1.5 is 3.375 which is (1.5)  and the explanation for D is that 2.5 times 1.25 Is 3.375 which is (1.5) Hope i helped:)

The expression is equivalent to 3.375 and 2.25 × 1.5.

We have to determine

Which expression is equal to [tex](1.5)^3[/tex]?

The expression is equivalent to;

[tex]= (1.5)^3\\\\= 1.5 \times 1.5 \times 1.5\\\\= 3.375[/tex]

Therefore,

The expression is equivalent to;

[tex]= 2.25 \times 1.5\\\\= 3.375[/tex]

Hence, the expression is equivalent to 3.375 and 2.25 × 1.5.
