4) It is known that 3 is the remainder when 99 is divided by a, and 70 is 2 short from being divisible by a. How many positive i
katrin2010 [14]

Answer:

  • 5 integers: {4, 6, 8, 12, 24}

Step-by-step explanation:

<u>From the given info we have:</u>

  • 99 - 3 = 96 is divisible by the number, the number is greater than 3 since the remainder was 3.
  • 70 + 2 = 72 is divisible by same number.

<u>Using the above info, find all factors of the two numbers, greater than 3:</u>

  • 96 = 4*24 = 6*16 = 8*12 = 12*8 = 16*6 = 24*4 = 32*3 = 48*2
  • 72 = 4*18 = 6*12 = 8*9 = 12*6 = 18*4 = 24*3 = 36*2

<u>The common divisors are:</u>

  • 4, 6, 8, 12, 24

I need help plz. Show your work! 23 + 5 x 3 - 100 + 19 in PEMDAS!
DaniilM [7]

Answer:

-43

Step-by-step explanation:

Follow PEMDAS as well as the left -> right rule.

Note that: PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, solve the multiplication:

23 + (5 * 3) - 100 + 19

23 + (15) - 100 + 19

Simplify. Follow the left-> right rule:

(23 + 15) - 100 + 19

38 - 100 + 19

(38 - 100) + 19

-62 + 19 = -43

-43 is your answer.

David and Patti each decomposed 138. David wrote 1 + 1/8 + 3/8. Patti wrote 4/8+2/8+5/8.
BaLLatris [955]

Answer:

Both are wrong.

Step-by-step explanation:

We have that:

Both decomposed the fraction \frac{13}{8} into a sum of fractions. Whoever's decomposition sum has a value of \frac{13}{8} is correct.

David:

1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}

\frac{12}{8} \neq \frac{13}{8}, which means that David is wrong.

Patti

\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}

\frac{11}{8} \neq \frac{13}{8}, which means that Patti is wrong.

So the answer is that both are wrong.

30% of a number is 45 what is the number ?
adell [148]

Hey there! I'm happy to help!

When talking about percents, the word "is" usually means equals. Let's use this to solve an equation! We will call our number n. Note that 30% is equal to 0.3 in decimal form because 0.3 is 30% of one! :D

0.3n=45

To solve, we need to isolate the n. To do this, we divide both sides by 0.3 because this cancels out the 0.3 that is being multiplied by n and it shows us what n will then equal.

0.3n÷0.3=45÷0.3

n=150

Therefore, 30% of 150 is 45. Try multiplying 0.3 by 150 and you will get 45!

Have a wonderful day! :D
