Answer:

A ) Distributive property, subtraction property of equality, subtraction property of equality, division property of equality.

Step-by-step explanation:

The given equation:

4 ( x + 5 ) = 2 x + 2

4 x + 20 = 2 x + 2 ( Distributive property ),

because: 4 · x + 4 · 5 = 4 x + 20

Then follows :  4 x - 2 x + 20 = 2 x - 2 x + 2  ( Subtraction property of equality )

2 x + 20 = 2

After that:

2 x + 20 - 20 = 2 - 20  ( Subtraction property of equality )

2 x = - 18

Finally:

x = - 18 : 2  ( Division property of equality )

x = - 9

45 + 57 = x + y<br> x= 37<br> y =?
Mekhanik [1.2K]

Answer:

y = 65

Step-by-step explanation:

45 + 57 = x + y

x = 37

45 + 57 = 37 + y

45 + 57 = 102

102 = 37 + y

102 = 37 + y

-37    -37

102 - 37 = 65

37 + y - 37 = y

65 = y

y = 65

Can someone walk me through how to do this problem please?​
Sholpan [36]

Hey!

----------------------------------------------------------------

We Know:

m∠AED = 34°

m∠EAD = 112°

----------------------------------------------------------------

Solution:

You notice 4 small triangles in both triangles. That shows that both triangles are the same.

The angles are the same for m∠BDC and m∠AED.

The angles are the same for m∠ADB and m∠EAD

----------------------------------------------------------------

Angles:

m∠BDC = 34°

m∠ADB = 112°

----------------------------------------------------------------

Congruent Angles:

m∠AED ≡ m∠BDC

m∠EAD ≡ m∠ADB

----------------------------------------------------------------

Hope This Helped! Good Luck!
