I believe the correct answer here would be C. x=10/3 because it is the only proportional answer.
Answer:
Step-by-step explanation:
b² - 4b - 12 = b² - 6b + 2b - 2*6
=b*(b -6) + 2*(b - 6)
= (b - 6) (b + 2)
b² - 4b - 12 = 0
(b - 6) (b + 2) = 0
b - 6 = 0 or b + 2 = 0
b = 6 or b = -2
Answer:
because in each case, the selected column composes one-tenth of the grid in total. The number of blocks is different, but the proportion of space filled is the same.
Step-by-step explanation:
This should be the correct answer
Answer:
3 1/3 metric tons per hour
Step-by-step explanation:
To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).
3 3/4 metric tons 3.75 metric tons
---------------------------- = --------------------------
1 1/8 hours 1.125 hours
It's easier to deal with decimal fractions here than with proper fractions.
The unit rate then comes out to be 3.75/1.125 metric tons per hour, or
3.33333 metric tons per hour, or 3 1/3 metric tons per hour
