What is the value of x?

Mathematics
1 answer:
stiks02 [169]2 years ago
4 0

Answer:

X= 15

Step-by-step explanation:

Since the angles are equal the equation to solve would be:

3x + 20 = 5x - 50

you will subtract 3x from 5x and get 2x

20 = 2x -50

subtract 20 from 50 to get 30

2x= 30

divide each side by 2

\frac{2x}{2}  = \frac{30}{2}

X= 15

Hope this helps

How do you do the question of 50%of 50 in math like how would you solve it
AveGali [126]

Answer:

25

Step-by-step explanation:

50% is half of something. half of 50 is 25.

Also there is another way to do it. 50/100 = 50%.

50/100 x 50 = 2500/100 = 25.  or 50/100 = 1/2. 1/2 x 50 = 50/2 = 25.

8n + 12 - 5n = 21<br> n=?
insens350 [35]

Answer:

n=3

Step-by-step explanation:

Simplifying

8n + 12 + -5n = 21

Reorder the terms:

12 + 8n + -5n = 21

Combine like terms: 8n + -5n = 3n

12 + 3n = 21

Solving

12 + 3n = 21

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-12' to each side of the equation.

12 + -12 + 3n = 21 + -12

Combine like terms: 12 + -12 = 0

0 + 3n = 21 + -12

3n = 21 + -12

Combine like terms: 21 + -12 = 9

3n = 9

Divide each side by '3'.

n = 3

Simplifying

n = 3
