= 5*675 - 5*3*210 - 210 ------------------------------ time's out bracket
=5*675 -210(5*3 +1) ---------------------------- took out common "-210" out of last
two terms'
= 5*675 -210(15+1)
= 5*675 -210(16)
=5*675 -210*16

Hello,
Answer: between 5 and 8 including 0 but not negative numbers.
Answer:
Yes. When looking at the word "TAKE" you can see that there are four letters. The probability of selecting the letter 'a' would be 1/4. The probability of selecting the letter 'k' would also be 1/4. This is because they are 1 out of 4 of the letters making up the word "TAKE". So, the outcomes are equally likely to occur.
Hope this helped.
Answer:
2.4 days
Step-by-step explanation:
Time working together,t ,is
1/t = 1/a+ 1/b where a and b is the times working alone
1/t = 1/4 + 1/6
Multiply each side by 12t to clear the fractions
12t( 1/t )= 12t(1/4 + 1/6)
12 = 3t+2t
12 = 5t
Divide by 5
12/5 = 5t/5
2 2/5 =t
