The sum of two numbers is 49 and the difference is 7 . what are the numbers?

1 answer:

5 0

Let one number be x.

Let the other number be y.

x + y = 49

x - y = 7

Subtracting both equations,

2y = 49 - 7 = 42

--- y = 21

--- x = 21 + 7 = 28

Hence the two numbers are 21 and 28.

Work Shown:

$(a * 10^b) \times (c * 10^d) = a*c*10^{b+d}\\\\(2.82 * 10^4) \times (3.1 * 10^3) = 2.82*3.1*10^{4+3}\\\\(2.82 * 10^4) \times (3.1 * 10^3) = 8.742*10^{7}\\\\$

Extra info:

$8.742 * 10^7 = 87,420,000$

49.5 is what percent of 33?

stira [4]

49.5/33 x 100= 150%. This is also rather simple to figure out just by looking at the question itself, you can clearly see that 49.5 is 16.5 greater than 33 and that 16.5 is half of 33. Which you can easily figure out from there.
