Which equation below would be best solved by using the addition property of equality?

- 23=45

237=45

F+23=45

F-23=45

F-23=45

Step-by-step explanation:

The addition property of equality means that if:

A = B

then we can add the same thing in both sides of the equation, and the equality will remain balid, so:

A + C = B + C.

Then, the correct answer is the last option:

if

F - 23 = 45

Then we can add the same number to both sides, we can add 23 to both sides and in this way isolate F:

F - 23 = 45

(F - 23) + 23 = 45 +23 = 68

F + (23 - 23) = 68

F = 68

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

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.
