Answer:
A reasonable estimate is [tex]1,900 * 300 = 570,000[tex]
Step-by-step explanation:
This is because 1,900 is the closest multiple of 100 for 1,912, and 300 is the closest multiple of 100 for 305. And [tex]1,900 * 300[tex] is [tex]19 * 3 * 10,000[tex].
Answer: Ron take approximately 4.2 hours to make 100 crusts alone.
Step-by-step explanation:
Since we have given that
Number of hours taken by Ron before Harold = 1.2 hours
Number of hours taken by Ron and Harold together = 1.8 hours
We need to find the number of hours taken by Ron alone i.e. 'x'.
Let number of hours taken by Harold alone be '1.2-x'.
Let work done by Ron alone =
Work done by Harold =
According to question, we get that
x-1.2 does not satisfied with x = 0.5 so, x = 4.2
Hence, Ron take approximately 4.2 hours to make 100 crusts alone.
Answer:
haha same
Step-by-step explanation:
i think the answer is B
7x + 5(x + 3) + 4x + x + 2 =
= 7x + 5x + 15 + 4x + x + 2 = 17x + 17
