To do the first question, simplify the equation, putting like terms together, by adding and subtracting to do this.

Then looking at the equation that you solved for, look and see if there are any other equations that are related in some way to the original solved equation.

Pay close attention to the positive and negative signs.

The difference between sixteen, and the product of seven and two

Monica [59]

Answer:

Step-by-step explanation:

If this product was written as an equation, it would look like this:

16 - 7 * 2

PEMDAS states that multiplication comes before addition. So, the first step in the equation is to multiply 7 and 2.

7 * 2 = 14

Now, the equation looks like:

16 - 14

All we need to do now is subtract 14 from 16.

16 - 14 = 2

So, the final answer is 2.

Kiley had a piece of bamboo skewer that measured 14Three-fifths inches long. She wanted to cut it into toothpicks that were each

forsale [732]

Answer:

4 toothpicks.

Step-by-step explanation:

We have been given that Kiley had a piece of bamboo skewer that measured 14 3/5 inches long. She wanted to cut it into toothpicks that were each 3 1/5 inches long.

To find the number of toothpicks that Kiley can make from bamboo skewer, we need to divide the length of skewer by length of each toothpick.

Total number of toothpicks = 14 3/5 ÷ 3 1/5

First of all, we will convert our given mixed fractions into improper fractions as:

Total number of toothpicks = 73/5 ÷ 16/5

Dividing a fraction by another fraction is same as multiplying the 1st fraction by the reciprocal of 2nd fraction.

Total number of toothpicks = 73/5 x 5/16

Total number of toothpicks = 73/16

Total number of toothpicks = 4.5625

Therefore, Kiley can make 4 toothpicks.

hope this helps, can i get brainliest please?
