Mary says the two expressions 4(5a-8)+2a and 12a-6 are equivalent is she correct

We have 4( 5a - 8 ) + 2a = 20a - 32 + 2a = 20a + 2a - 32 = 22a - 32 =

2( 11a - 16);

The two expressions 2( 11a - 16) and 12a - 16 aren't equivalent.

Step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
