Answer:

x=7

7-4=3

7+2=9

Step-by-step explanation:

Triangle ABE and Triangle CDB are similar

4*3=12

ABE is 3 times bigger than CDB

3(x-4)=x+2

3x-12=x+2

2x-12=2

2x=14

x=7

7-4=3

7+2=9

10p = 66 what is the value of p
Zepler [3.9K]
The value of p is 11. To find this, you must isolate the variable, p, so you divide 10 by both sides of the equation to get p=11.

The sum of two numbers is 22 and their difference is 12 what are the numbers
nlexa [21]

Answer:

The numbers are 17 and 5

Step-by-step explanation:

x + y = 22

x - y = 12

Add y to both sides of the equation

x = 12 + y

Substitute new value for x into first equation

12 + y + y = 22

Add the y's

12 + 2y = 22

Subtract 12 from both sides

2y = 10

y = 5

22 - 5 = 17

The numbers are 17 and 5

Hope this helps :)
