what is the solution for X in the equation -4 + 5x - 7 equals 10 + 3 x - 2x

choices:
A- x= 4/21
B- x= 13/4
C- x= 4/13
D- x= 21/4
​

Answer:

2.11

Step-by-step explanation:

3.5 x 2 + 9 = 16

10.4 - 1.4 x 2 = 7.6

16/7.6

= 40/19 or 2.11 to the nearest hundredth

Therefore the answer is 2.11

Answer:

[tex]x=3[/tex]

Step-by-step explanation:

The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:

[tex]7 = 2x + 1[/tex]

Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:

[tex]6 = 2x[/tex]

The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:

[tex]3 = x[/tex]

Step-by-step explanation:

For every increase in the x-value by 1,

the y-value decreases by -2.

(From 3 to 1 and from 1 to -1)

Hence, slope of line k

= Rise/Run = (-2)/1 = -2. (A)

Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.

Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.

In this problem, two of the points are: (1,3) and (2,1).

Hence, applying the division:

[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]

The slope of the line is of -2, hence option A is correct.

Answer: 100 miles.

Step-by-step explanation:

Here , Flat fee = $ 5.00

Additional charge per mile = $ 0.05

Money spent = $ 10

Formula : Total Charge =  Flat fee + (Number of miles ) x (Additional charge per mile)

Let x= Number of miles

Substitute values , we get

10 = 5 + 0.05x

⇒ 0.05x= 5

⇒ x = 100

Hence, I took bike for 100 miles.

Answer:

x= 11.04

In mathematics, proportions refer to the equality of two ratios. A ratio is a comparison of two quantities, typically expressed as a fraction. When two ratios are equal to each other, they form a proportion.

A proportion can be written in the form:

a/b = c/d

Here, "a" and "b" are the terms of the first ratio, and "c" and "d" are the terms of the second ratio. The proportions state that the ratio of "a" to "b" is equal to the ratio of "c" to "d".

Answer:

60

Step-by-step explanation:

The required number is 60.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now the given expression is,

4.5 is 7.5%

Let x be the number.

Therefore, 7.5% of x is 4.5

⇒ 7.5% of x = 4.5

⇒ 7.5% * x = 4.5

⇒ 7.5/100* x = 4.5

⇒0.075 x = 4.5

Dividing both side by 0.075 we get,

x = 4.5 / 0.075

Solving we get,

x = 60

this is the required number.

Thus,the required number is 60.

Answer:

$216

Step-by-step explanation

We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.

250 * 0.8

This will give us 200.

Now, we need to add the sales tax which is 8%.

Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.

200 * 1.08 = $216
