Simplify this expression.<br> 20.25 – 9 + 11<br> о<br> 1<br> 4<br> 0 18.75<br> 0<br> 21?<br> 0 40.75
Greeley [361]

Answer:

21\frac{3}{4}

Step-by-step explanation:

Step 1: Add the numbers.

20.25 can also be expressed as 20\frac{1}{4}, because \frac{2025}{100} = \frac{81}{4} = 20\frac{1}{4}. So if we add 20\frac{1}{4} and 11, we would get 31\frac{1}{4}

Step 2: Solve

31\frac{1}{4} -9\frac{1}{2}

  • Subtract the whole numbers

31-9=21

  • Combine the fractions

This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.

\frac{5}{4}-\frac{1}{2}

LCM

\frac{5}{4}-\frac{2}{4} =\frac{3}{4}

Therefore, the simplified expression to this is 21\frac{3}{4}.

Rick and Sara have two children, Marcos and Jade. Use the clues to determine their ages. Rick is 4 years younger than Sara. Marc
Morgarella [4.7K]

Step-by-step explanation:

Let age of rick = x

age of sara = y

age of marcos = a

age of jade = b

Rick is 4 years younger than Sara.

x = y - 4

Marcos is 3 years older than Jade.

a = b + 3

Rick's age is twice the age of Marcos and Jade's ages combined.

x = 2(a+b)

The youngest is 9 years old.

The youngest is jade because rick and sara are the parents and marcos is older than she is.

b = 9

How old is each??

a = b + 3

a = 9 + 3 = 12

Marcos is 12 years old

x = 2(a+b)

x = 2 (12 + 9)

x = 2 (21) = 42

Rick is 42 years old

x = y - 4

42 = y - 4

y = 42 + 4 = 46

Sara is 46 years old
