So you have 12 cases delivered in 1 hour and 30 minutes. 30 minutes is half of an hour or .5
so 12/1.5 is 8, that is 8 cases per hour for a total of 32 cases in 4 hours.
Answer:
750 minutes
Step-by-step explanation:
8 pages in 20 minutes
300 / 8 = 37.5
37.5 * 20 = 750
Answer:
incorrect, correct answer is 4√2
Step-by-step explanation:
When you remove the square root You will have to remove them completely. so that the inside of the square root cannot be removed any more numbers (I'm not good at English but I hope u understand what I want u to know :)))
√32 = √2×2×2×2×2
Match 2 identical numbers one at a time and bring them out. ;
√32 = 2×2√2
√32 = 4√2 correct answer!
find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:
4√2 × 4√2 = 16×√4 = 16×2 = 32 correct!
hope it helps you <3
If you distribute -5 to the things in the parenthesis you would get 10k-20 which is the same as -5(-2k+4)
When using substitution, you want to solve an equation for one variable that doesn’t make the equation worse to work with.
The general idea is that you want to find a variable that has a coefficient of 1 or -1.
In 2.5x - 7y = 7.5, both variables have “bad” coefficients.
In 6.2x - y = 1, the y has a coefficient of -1. That’s where you want to start.
