How do I figure out solve kx+7=4 for x​

Mathematics
1 answer:
Vedmedyk [2.9K]3 years ago
6 0
<h3>Answer:   x = -3/k</h3>

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

Work Shown:

kx+7 = 4

kx+7-7 = 4-7 .... subtract 7 from both sides

kx = -3

kx/k = -3/k .... divide both sides by k

x = -3/k

The value of k cannot be zero. As the steps show, we are following PEMDAS in reverse to undo each operation to help isolate x. Subtraction is the opposite of addition, and division is the opposite of multiplication.

For each situation, determine the slope and y-intercept if the graph of the equation that describes the situation.
Serggg [28]

So the slope is 200 as he gains $200 each day

and the y intercept is 500, since he receives the $500 only once

y = 200x + 500

An auto parts chain asked customers to complete a survey rating the chain's customer service as average, above average, or below
Mandarinka [93]

Answer:

The right answer is "0.33".

Step-by-step explanation:

As per the question,

n = 15

Average will be "x = 5"

Now,

The required proportion will be:

⇒ p=\frac{x}{n}

By putting the values, we get

⇒     =\frac{5}{15}

⇒     =0.33

Thus, the above is the appropriate solution.

2L + 2W = 88<br> L = W + 12<br> What are the dimensions?
liraira [26]

Answer:the length of the rectangle is 28

The width of the rectangle is 16

Step-by-step explanation:

The given equations are set up to determine the dimensions of a rectangle. L represents the length of the rectangle. W represents the width of the rectangle. Let us label

2L + 2W = 88 as equation 1.

We would substitute L = W + 12 into equation 1, it becomes

2(W + 12) + 2W = 88

2W + 24 + 2W = 88

4W + 24 = 88

4W = 88 - 24 = 64

W = 64/4 = 16

Substituting W = 16 into L = W + 12, it becomes

L = 16 + 12 = 28
