Answer:

14, 2 and -8 all can be divided by the greatest number, 2.

Step-by-step explanation:

If you do not want a decimal number for each, then first you would choose an even number. Odd numbers will likely make 14, 2 and -8 a decimal.

Dividing by 1 makes the numbers 14, 2 and -8. 1 is an odd number, but it does not affect any of the numbers. However, there may be a better number.

Dividing by 2 makes the numbers 7, 1 and -4. So far this number works to divide them all.

Dividing by 4 makes the numbers 3.5, 0.5 and -2. Only one number is not a decimal, so this does not work.    

Dividing by 6 makes the numbers  2.333..., 0.333... and -1.333... All of these numbers are decimals. This will not work either.

We can conclude that any number greater than 2 will not make all the numbers whole. They will be made irrational and decimal.

So 2 is the greatest number that can divide into all of the numbers.

Gerri spends 1/21 of her money on pencils and 2/21 on paper. What fraction of her money does she spend. Give the answer in simpl
BigorU [14]

Answer:

Gerri spends 1/7 (A).

Step-by-step explanation:

If Gerri spends 1/21 of her money on pencils and 2/21 of her money on paper, adding these two fractions together will give us the total fraction of her money that she spent.  Since 1/21 and 2/21 have the same denominator, we can add the numerators to get 3/21.  However, fractions must always be in simplest form, meaning if the numerator (top number) and denominator (bottom number) can both be divided evenly by the same factor, then the fraction can be simplied to lower numbers.  In this case the number 3 and the number 21 can both be divided evenly by 3:  (3÷3)/21÷3) = 1/7.

5(-3x - 2) - (x - 3) = -4 (4x +5) + 13
S_A_V [24]
Start off by distributing the numbers into the parentheses:

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
-15x - 10 - (x - 3) = -16x - 20 + 13

(Note: It's super important to be careful when opening up negative parentheses! -(x-3) is not just - x - 3, it is actually -x + 3 since the negative is distributed in every number!)

-15x - 10 - x + 3 = -16x - 20 + 13
-16x - 7 = -16x - 7
-16x = -16x
0 = 0

There is an infinite number of solutions in this equation.

(When you get 0=0 when solving for a variable, that means that said variable will have infinite solutions, that is, any number plugged into the equation will work)
