HELP ASAP Name the property used to make the conclusion:
3. If x + 7 = 23, then x = 16.
7. If x - 24 = 25, then x = 49.

a. addition property of equality
b. subtraction property of equality
c. multiplication property of equality
d. division property of equality
e. symmetric property of equality
f. substitution property of equality

Note: They said 3. is NOT A and 7 is NOT B

Step-by-step explanation:

3. If x + 7 = 23, then x = 16

7. If x - 24 = 25, then x = 49.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
