this is confusing where is angle b , a, and c
Your brother is now 11. If your brother is 3, you put '8+x'=x+5 to get your cousins age. Once you have x+5, set it equal to 2(x-3) and solve that. You should get x+5=2x-6 and you get x=11. You add 8 to get your cousins age. So your brother is 11 and your cousin is 19.
Answer:
1/3 or 0.333
Step-by-step explanation:
If we know that exactly 2 of the 6 rolls resulted in a 1. Then the number of ways to arrange the two 1s into 6 slots is
ways
Of these 15 ways, some of them have 1 at the 1 slot.
The number of ways to arrange the two 1s so that one 1 is in the 1st slot is 5. Because the 2nd 1 is in any of the other 5 slots.
Therefore, the probability that the first roll resulted in a 1,given that exactly two of the six rolls resulted in a 1 is
5 / 15 = 1/3 or 0.333
Answer:
They are not equivalent equations
Step-by-step explanation:
d=m/v
Multiply each side by v
d * v = m/v *v
dv = m
Divide each side by d
dv/d = m/d
v = m/d
This is not the same as v = m-d
They are not equivalent equations
