Answer:

10/3

Step-by-step explanation:

Answer:

x is being multiplied by 7p so to find x you need to have it alone on one side of the problem, so you could divide both sides by 7p, making it look like 2n+3pm/7p=x (simplify if needed)

Step-by-step explanation:

Answer:

x = 51°

Step-by-step explanation:

The image of the triangle is an isosceles triangle. Since it is an isosceles triangle, ∠DFE = ∠FDE.

78 + x + x = 180

=> 2x = 102

=> x = 51°

Answer:

20

Step-by-step explanation:

I did this test is 20

60 percent of 20 is 12 dollars

The original price of a pair of jeans would be; 30 dollar.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b% Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Given that a pair of jeans is only $12 after a 60% discount.

The original price in percentage terms = 100%

After the first discount, the price is : 100- 60% = 40%

The equation can be used to represent the price;

40% x original price = $12

0.40 x p = 12

where p = original price

Divide both sides of the equation by 0.40;

p= $30

Hence, The original price of a pair of jeans would be; 30 dollar.

The proportion which represents the 65% of 90 is:

Step-by-step explanation:

Given information:

We need to find the proportion that can be used to find

65% of 90

Let us take :

% of

So,

Hence , the proportion which represents the 65% of 90 is

Answer:

The proportion [tex]\frac{65}{100} = \frac{x}{90}[/tex]

Step-by-step explanation:

[tex]\frac{65}{100} = \frac{x}{90}[/tex]

(65)(90) = 100x

5850/100 = x = 58.5

58.5 = 65% of 90

Alternatively, you can use the more direct approach:

[tex]\frac{65}{100} (90)[/tex]

= [tex]\frac{65 * 9}{10}[/tex] = 585/10 = 58.5

Answer:

16= 4x+8

16-8=4x

x=8/4

x= 2

Step-by-step explanation:

16=2(2x+4) 16=(2×2x) + (4×2) 16= 4x+8. 16-8=4x+8-8. 8=4x. 8/4=4x/4. 2=x

The logarithmic property chosen here is:

[tex]log_{a}[/tex] m - [tex]log_{a}[/tex] n = [tex]log_{a}[/tex] [tex]\frac{m}{n}[/tex], and its validity is proven below:

The logarithmic properties are up to six, but one of it that is applicable here is:

[tex]log_{a}[/tex] m - [tex]log_{a}[/tex] n = [tex]log_{a}[/tex] [tex]\frac{m}{n}[/tex]

In the above expression, both the numerator and denominator have the same base number, but different powers. So in this case, dividing a number of power m by the same number but of power n would given an answer that is the same as the number to the power of the difference between m and n.

For example: Solve;

a. [tex]log_{10}[/tex] 6 - [tex]log_{10}[/tex] 3

b. [tex]log_{10}[/tex] 8 - [tex]log_{10}[/tex] 5

c. [tex]log_{b}[/tex] 6 - [tex]log_{b}[/tex] 2

Solutions:

a. [tex]log_{10}[/tex] 6 - [tex]log_{10}[/tex] 3 = [tex]log_{10}[/tex] [tex]\frac{6}{2}[/tex]

        = [tex]log_{10}[/tex] 2

        = 0.3010

b. [tex]log_{10}[/tex] 8 - [tex]log_{10}[/tex] 5 = [tex]log_{10}[/tex] [tex]\frac{8}{5}[/tex]

      = [tex]log_{10}[/tex] 1.6

       = 0.2041

c. [tex]log_{b}[/tex] 6 - [tex]log_{b}[/tex] 2 = [tex]log_{b}[/tex] [tex]\frac{6}{2}[/tex]

        = [tex]log_{b}[/tex] 3

The stated examples defend the validity of the specific logarithmic property.

Hope this helped

Step-by-step explanation:

1) 3 – 36i = 9a + 4bi

3 = 9a => a = 3/9 = ⅓

-36 = 4b => b = -36/4 = -9

2) a – 15i = -7 – (2b-3)i

a = -7

-15 = -(2b-3)

2b-3 = 15

2b = 18

b = 18/2= 9

Step-by-step explanation:

Slope- intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Slope

= 0.25

= ¼

Substitute m= ¼ into the equation:

y= ¼x +c

Given that the y-intercept is -11, c= -11.

Thus, the equation of the line is y= ¼x -11.

Have a nice day

Answer:

Step-by-step explanation:

This is late but the other is not an answer at all.

The 50 ft string makes an angle of 39 degrees with the ground so the stromg and balloon form a right-angle triangle to the ground.

The height of balloon from string = 50*sin(39degrees)

= 31.47 ft

As the string is held by a person 5 ft above ground, the balloon is above ground at 31.47 + 5

= 36.47 ft.

The graph of the equation, y = 4x, is shown below.

Given an equation, for example, y = 4x, to plot it on a coordinate plane, we need to find the coordinates of the line that we would plot and connect together to graph the equation.

Find the corresponding y-values when x = 1, x = 2, and x = 3. To do this, see the steps below:

Substitute x = 1 into y = 4x:

y = 4(1)

y = 4

We have a point, (1, 4).

Substitute x = 2 into y = 4x:

y = 4(2)

y = 8

We have another point, (2, 8).

Substitute x = 3 into y = 4x:

y = 4(3)

y = 12

We have a third point, (3, 12).

Plot the three points on a coordinate plane as shown below to get the graph of the equation.
