How do i check 8d-25=3d

d=5

Step-by-step explanation:

That is the answer if that is what you were looking for.

your welcome

8d-25=3d

8d-3d=25

5d=25

d=5

d=5

8d-25=3d

8(5)-25=3(5)

40-25=15

15=15 so it’s right

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

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
