Answer:

c = 5

Step-by-step explanation:

c/6 - 4/9 = 7/18

Make denominators equal.

3c/18 - 8/18 = 7/18

Cancel denominators since they are equal.

3c - 8 = 7

Add 8 to both sides.

3c = 7 + 8

3c = 15

Divide 3 into both sides.

c = 15/3

c = 5

Find the value of x 9.10.12,x, 20.25 ; The median is 14.

Elodia [21]

Answer: 16

Step-by-step explanation:

9,10,12,x ,20, 25 so we know the median is 14 which is the middle number.

Since the numbers are 6 it means there will be 2 middle numbers and if you divide them it will be 14.

we know one of the middle numbers is 12 and we trying to find x .

So we could use the equation x + 12 = 2(14)

x + 12 = 28

-12 -12

x= 16 so X is 16. check: 16+12=28/2 is 14.

Complete the equation for the standard form of the line that has an x-intercept of -5 and a y-intercept of -4.

Verdich [7]

Answer:

Intercept form $\frac{x}{-5} + \frac{y}{-4} = 1$

The standard form of the equation of the line

4 x + 5 y +20 =0

Step-by-step explanation:

Explanation

Given that x-intercept (a) = -5

and y-intercept (b) = -4

Intercept form

$\frac{x}{a} + \frac{y}{b} = 1$

$\frac{x}{-5} + \frac{y}{-4} = 1$

⇒ $\frac{4x+5y}{-20} = 1$

4 x + 5 y = -20

Final answer:-

The standard form of the equation of the line

4 x + 5 y +20 =0
