Let b>a

b+a=52

b=52-a, we are also told that the larger number, b, is 3 times the smaller a:

b=3a, since b=b we can say:

3a=52-a

4a=52

a=13, and since b=3a

b=39

So the numbers are 13 and 39

<span> Let x be the smaller number.
Then 3x is the larger number.
We also know that the smaller added to the larger is 52, or:
x + 3x = 52
4x =52
x = 13
Therefore the smaller is 13, the larger is 3(13)=39. </span>

My ones digit is twice the hundreds digit

BlackZzzverrR [31]

The hundreds digit is twice as large as the ones digit. 3 doubled is 6, 6 doubled is 12, and 9 doubled is 18. Since 6 is the only option that is one digit, the hundreds digit must be 6 and the ones digit must be 3. The tens digit is five less than the hundreds digit.

Got you. So we will use the basic formula for the area of a rectangle and insert variable values. (^_^)

Area= Width(Height) ----------- Insert values of width and height [width = (x-1)
, height = (x+9)]

Area= (x-1)(x+9) ) -------------- Then expand if needed?
= x² +8x -9

The table gives the average age of airplanes per airline at Camila’s local airport. By what percent is the number of airlines wi

VladimirAG [237]

The percentage that the number of airlines with an average airplane age of 14 is less than the number of airlines with an average airplane age of 11 is:

B. 20%.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

The percentage of airlines with an average age of 14 years is:

$P = \frac{2}{15} \times 100\% = 13.33\%$

The percentage of airlines with an average age of 11 years is:

$P = \frac{5}{15} \times 100\% = 33.33\%$

The difference is:

33.33% - 13.33% = 20%.

Hence option B is correct.
