A teacher is covering a bulletin board with fabric. He has a piece of material that is 2 yards long and 36 inches wide. What size bulletin board can he cover with the material?

Answers

36'' = 1 yard
The teacher can cover a bulletin board with size 2 yards^2

Well to start our problem we need to find the information that is most important. 2 yards and 36 inches wide, and "What size bulletin board can he cover with the material?". Now that we have our information we can figure this out : 36 : 1y yard so 2y by 36in aka 2/36, so......our work can lead us too : 2 yards *squared* or 2 yards^2. Hopes I helped!

Max was solving the equation below and isn’t sure if his answer is correct. Explain to Max how he can check his answer and then help him identify any errors he made. Provide the correct solution in your How can he check his answer?

Show the correct solution:

Answers

HOW CAN HE CHECK HIS ANSWER:
HE CAN CHECK HIS ANSWER BY PLUGGING IN HIS X VALUE, AFTER HE GETS THE CORRECT ANSWER.
SHOW THE CORRECT ANSWER:
3(3x+6) = 4(7x-1)
9x+18 = 28x-4
18 = 19x-4
22 = 19x
22/19 = x

CHECK:
3(22/19+6)/8 = 7(22/19-1)/6
45/38 = 45/38 ( Is true)

hope this helps!!

Well, first of all, the bottom 2 lines are cut off of the bottom of Max's solution,
and his final answer doesn't even appear there.

Here . . . let me complete it for you:
Under the part printed on the page should be:

   19 = 19x

   x = 1

=========================================

Now that Max has an answer, he can check it by writing it into the
original equation wherever there's an 'x' there.

The original:    (3x-6) / 8 = (7x-1) / 6

With Max's answer written in: (3·1 - 6) / 8 = (7·1-1) / 6

Simplify the left side:    (3 - 6) / 8 = (7·1-1) / 6
-3/8 = (7·1-1) / 6

Simplify the right side: -3/8 = (7-1) / 6
-3/8 = 6 / 6
-3/8 = 1
This result is not a true statement,
so 'x' can't be ' 1 '.

We have to go back, look through Max's work, and find his mistake.
(Actually, Max won't learn anything that way ... MAX should be looking through
his work to find his mistake. But life is not always fair.)

The third line of Max's solution is 3 (3x + 6) = 4 (7x - 1)

Then he goes on to clear the
parentheses, and the next line is: 9x + 18 = 28x - 1

That's where his mistake is. The left side is correct,
but on the right side, Max distributed the '4' incorrectly.
Shame on Max.
This line should be    9x + 18 = 28x - 4 .

There's no "answer." All you can do here is to combine the terms and simpify the resulting sum.
