Answer
Cameron forgot to do the same thing to the 9. Instead of dividing 3 by 3 and 9 by 3 he only divided 3 by 3.
Step-by-step explanation:
3/7 × 4/9
You can divide the 3 and 9 by 3 so you get 1/7 × 4/3.
Then you do 4 × 1 and 7 × 3.
Correct answer is 4/21
Answer:
115
Step-by-step explanation:
4*2+8(2) = 24
31
7(2)+30 = 44
3*2-5(2)+20 = 6-10+20 = -4+20 = 16
24+31+44+16
115
Answer:
Numbers greater than 4 are 5 and 6
So we have 2 numbers out of 6 numbers so the probability is equal to 2/6 = 1/3
And 1/3 of 12 is equal to 4
So Brian expect to roll a number greater than 4,
Four times.
First, you must get rid of the fractions. You can do that by multiplying that 15. Then, you get:
45x-12=-5x
Then combine the like terms
50x=12
x=12/50=6/25
