Evaluate qr/q + r when q = 8 and r = 13

so it would be 8x13/8+13, which would simplify out to be 104/8+13 which would then simplify out even more to be 104/21 as a fraction or 4.95 as a decimal

hope this helps!! :) ❤❤❤❤

Your going to substitute in the numbers for the variables.

8*13 / 8 + 13 =

8*13 = 104

104/ 8 + 13 =

8 + 13 = 21

104/21= 4.95

So the answer is 4.95.

Hope this Helps!!

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
