I am so confused, can someone help
marta [7]

Answer:

Step-by-step explanation:

a. To solve for "y" you want to isolate the variable. What this means is you want to keep "y" on its own. To do this first we will subtract 2x from the equation making 4y = 36 - 2x. Next, we will get rid of 4 to do this divide 4 from both sides. y = (36 - 2x)/4

*I have to go in a bit so sry for no explenation*

b. h = 2a/b

c. x = 1/4y + -3/4

HELP!!! CORRECT ANSWER NEEDED OR ELSE I FAIL ;-; STUDY ISLAND !!
Ket [755]

Answer:

  B.  Step 2 uses the associative property, and step 3 uses the commutative property.

Step-by-step explanation:

The associative property lets you group terms for addition any way you like. It appears that in Step 2, the grouping is ...

  4 + (1/6 + 3) + 5/6

The commutative property lets you change the order of any pair of terms involved in addition. It appears that in Step 3, the order of the terms within the group has been swapped.

  4 + (3 + 1/6) + 5/6

_____

<em>Comment on associative and commutative properties</em>

What applies to terms in addition applies to factors in multiplication.
