Pretty sure b is correct because you are cross multiplying.
You have 30 cubes... you take those cubes into groups of 4
which you will end up with 7 groups of 4 and one group of 2 to equal 7.5
Answer:
91
Step-by-step explanation:
Todd’s average score for six tests = 92.
The sum of two of her test = 188
First, we need to find the total score for the six test. This given below:
Average = sum of all test / number of test
sum of all the test = average x number of test
average score for six tests = 92.
Number of test = 6
Sum of all the Tests = 92 x 6 = 552
Sum of four test = sum of all the test — sum of two test
Sum of four test = 552 — 188 = 364
Now we can solve for the average of the other four test as shown below:
Average of four test = 364/4= 91
Answer:
-3
Step-by-step explanation:
f(-2) = (-2)^2 + 10 = 14 -> (-2, 14)
f(-1) = (-1)^2 + 10 = 11 -> (-1, 11)
(11-14)/(-1-(-2)) = -3/1 = -3
