You need to factor the radicals into products of radicals, and when factoring you should keep in mind you want to obtain perfect square roots. So √125 = √5*√25 and squareroot 25 has a definite answer of 5, so ∛125=∛5×∛25=5×√5. You want to follow the general pattern of factoring perfect squares to obtain a number outside the radical which can be multiplied by the current coefficient
Answer:
3ab+5b-6 = 0
Step-by-step explanation:
3ab+5b-6
a =-1 and b=3
Solve :
3ab+5b-6
= 3(-1)(3) + 5(3) - 6
= -9 + 15 - 6
= 0
Let's say he has 1 kg of each
2.25/kg and 3.75/kg
add together and divide by 2 to get average
6/2=3
so it must be a one to one ratio
25 kg/2=12.5 kg of each
12.5 of each brand
If two events are dependent on each other you have to multiply the probability of the first event times the probability of the second event.
first count all the marbles here there are 21
you are asked about picking two green marbles there are 7 out of the 21 total.
The first event would be 7/21
The second event would be 6/20 (since you didn't replace and you took out a green one)
now multiply your two fractions together:
and you get 1/10.
