B: Alex is 12 years older than George.
UkoKoshka [18]

Answer:

The ratio of George age to Carl's age is 1:12.

Step-by-step explanation:

Let the age of George be 'g'.

Let the age of Alex be 'a'.

Also Let the age of Carl be 'c'.

Given:

The sum of their ages is 68.

So equation can be framed as;

g+a+c=68 \ \ \ \ equation 1

Also Given:

Alex is 12 years older than George.

So equation can be framed as;

a =g+12 \ \ \ \ equation \ 2

Now Given:

Carl is three times older than Alex.

c=3a

But a =g+12

So we get;

c = 3(g+12) \\\\c= 3g+36 \ \ \ \ equation \ 3

Now Substituting equation 2 and equation 3 in equation 1 we get;

g+a+c=68\\\\g+g+12+3g+36=68\\\\5g+48=68

Subtracting both side by 48 using subtraction property of equality we get;

5g+48-48=68-48\\\\5g=20

Now Dividing both side by 5 using Division property of equality we get;

\frac{5g}{5}=\frac{20}{5}\\\\g =4

Hence George age g = 4 \ years

Now Alex age a=g+12 = 4+12 =16\ years

Also Carl's age c=3g+36=3\times 4+36 =12+36 =48\ years

Now we need to find the ratio of George age to Carl's age.

\frac{g}{c}=\frac{4}{48} = \frac{1}{12}

Hence  the ratio of George age to Carl's age is 1:12.

Solve the equations involving exponents<br><br><br> 1. Solve 5^4x5^8=?<br><br> 2. 11^18/11^-4=?
den301095 [7]
When you multiple same numbers with different exponents, the exponents add. Example x^2 * x^3 = x^4
When you divide same number with different exponents, the number subtracts

1. 5^4 * 5^8 = 5^12
2. 11^18/ 11^-4 = 11^22

Can you guys help me with this
katen-ka-za [31]

Answer:

Step-by-step explanation:

Let the number of small boxes = x

and the number of large boxes = y

Total number of boxes = 24

Therefore, equation will be,

x + y = 24 ------ (1)

Since, volume of the smaller boxes = 9 cubic feet

And the volume of larger boxes = 24 cubic feet

Therefore, total volume of the boxes = (9x + 24y)

Since combined volume of all boxes = 441 cubic feet

Therefore, equation will be,

9x + 24y = 441 ------ (2)

Write 43/19 as a decimal rounded not the nearest 100th
Xelga [282]

Answer: So you're looking for 43/19 but not to the nearest hundredth, so maybe your teacher is looking for the decimal to be rounded to the nearest tenth or one thousandth... Here's how you would solve this...

Step-by-step explanation:

49/13 or 49 ÷ 13

49/13 = 3.76923076923

To the Nearest 10th: Answer ≈ 3.8

To the Nearest 1,000th: Answer ≈ 3.769

To the Nearest 100th: Answer ≈ 3.77

Note: I listed the nearest 100th in case you need it, I hope this helps you!
