Since vertical angles are congruent, in order to find the value of x we must equal the two values to each other.

3x+50=6x-10
add 10 to both sides.
3x+60=6x
subtract 3 from both sides
60=3x
divide both sides by 3
x=20

These are vertical angles and they are equal

3x + 50 = 6x - 10
50 + 10 = 6x - 3x
60 = 3x
60/3 = x
20 = x <==

Show how to make ten to solve 13-7. Write in a number sentence. _-_-_-_-_=_

ser-zykov [4K]

Answer: The answer is 6.

The number sentence is

3-3=0

10-4=6

So, 13-7=6

Step-by-step explanation:

To solve $13-7$ , by making ten

First break 13 and write $13=10+3$

Then break 7 as $7=3+4$

Now to subtract 7 from 13,

Step 1. Subtract 3 (a part of 7), from 3(a part of 13) or cross 3 circles, then we have left 10-4

$13-7=10+3-(3+4)=10+3-3-4=10-4$

Step 2. Subtract 4 from 10 or cross 4 circles out of 10, we get 6.

The answer is 6.

Answer:

32.5

Step-by-step explanation:

If CED is 65, then AEB is 65, therefore we can calculate that CEA is 115 because 180 - 65 = 115. Then we do 180 - 115 = 65 which is the sum of angles ACE and CAE so 65 / 2 = 32.5 which is CAE.

Hope this helped!
