One number is nine more than another number. if the sum of numbers is 65, find both numbers

The Answer is that the first number is 37 and the second number is 28.

Step-by-step explanation:

Let f = first number and s = second number

f = s + 9

The sum of both numbers is 65:

f + s = 65

Substitute:

(s + 9) + s = 65

2s + 9 = 65

2s = 65 - 9

2s = 56

s = 56 / 2 = 28, the second number.

f = s + 9

f = 28 + 9 = 37, the second number.

Proof:

f + s = 65

28 + 37 = 65

65 = 65

Here you go! Hope this helps and have an Awesome Day!! :-)

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
