Answer:

  y > 11/2

Step-by-step explanation:

This is solved the same way a 3-step equation is solved.

<u>Step 1</u>: subtract the smaller variable term from both sides.

  4y -2y +3 > 2y -2y +14

  2y +3 > 14

<u>Step 2</u>: subtract the constant with the variable term.

  2y +3 -3 > 14 -3

  2y > 11

<u>Step 3</u>: divide by the coefficient of the variable.

  2y/2 > 11/2

  y > 11/2

_____

<em>Additional comment</em>

By choosing to subtract the smaller variable term in the first step (regardless of which side of the inequality it is on), we ensure that the remaining variable coefficient is positive. That means we can do step 3 without worrying about changing the direction of the inequality symbol, because we're dividing by a positive number.

Matt is showing his work in simplifying (6.2 − 1.6) − 4.4 + 7.8. Identify any error in his work or reasoning. Step 1: (6.2 − 1.6
Black_prince [1.1K]

Answer:

The correct option is (d)-He wrote commutative instead of associative in Step 2.

Step-by-step explanation:

Commutative property: a+b=b+a

Associative property: (a+b)+c=a+(b+c)

Now consider the provided expression.

(6.2 − 1.6) − 4.4 + 7.8

Step 1

(6.2 − 1.6) − 4.4 + 7.8

Step 2 Use Associative property

6.2 + (−1.6 − 4.4) + 7.8

Step 3: Simplify

6.2 − 6 + 7.8

Step 4: Use commutative property

14 − 6

Step 5: Simplify

14 − 6 = 8

Hence, the wrong step is step 2. He wrote commutative instead of associative in Step 2.

Therefore, the correct option is (d)-He wrote commutative instead of associative in Step 2.
