Solve Absolute Value.

|2x+3|<9

We know2x+3<9and2x+3>−9

2x+3<9

2x+3−3<9−3(Subtract 3 from both sides)

2x<6

2x/2 < 6/2

Divide both sides by 2

x<3

2x+3>−9

2x+3−3>−9−3

Subtract 3 from both sides

2x>−12

2x/2 > −12/2

Divide both sides by 2

x>−6

Answer is x<3 and x>−6

Sarah cut off 1/8 of a 48 inch piece of ribbon. Jane cut off 1/9 of a 36 inch piece of ribbon. They compared their cut pieces. W
Otrada [13]

Answer:

Sarah's, 2 inches.

Step-by-step explanation:

Given:

Sarah cut off 1/8 of a 48 inch piece of ribbon.

Jane cut off 1/9 of a 36 inch piece of ribbon.

Question asked:

Whose piece is longer ?

How much longer ?

Solution:

As Sarah cut off 1/8 of a 48 inch piece of ribbon, means she has cut piece of size:

\frac{1}{8} \ of \ 48\\\frac{1}{8} \times48 = \frac{48}{8} = 6\ inches

As Jane cut off 1/9 of a 36 inch piece of ribbon, means she has cut piece of size:

\frac{1}{9} \ of \ 36\\\frac{1}{9} \times36 = \frac{36}{9}  = 4 \ inches

As Sarah has 6 inches piece of ribbon and Jane has 4 inches piece of ribbon so Sarah's piece longer.

Now, to find it is how much longer we will subtract Jane's piece of ribbon from Sarah's piece of ribbon,

6 inches - 4 inches = 2 inches.

And hence,  Sarah's piece of ribbon is 2 inches longer than Jane's  piece of ribbon .

13. Find the smallest number which when divided by 21,28,36 and 44 leaves a
OleMash [197]

Answer:

2775

Step-by-step explanation:

Well of course since the problem is not restricted, the smallest number is 3. I'm almost sure that's not what you mean. The next smallest number is 2775. I found that using a  programing language. I'm sure as well that does not satisfy the question, either.

I think you are intended to do this by finding the lowest common multiple and adding 3.

21: 3 * 7

28: 2 * 2 * 7

36: 2 * 2 * 3 * 3

44: 2 * 2 * 11

LCM = 2 * 2 * 3 * 3 * 7 * 11 = 2772

Now add 3 and the number you want is 2775
