Answer:
<em>9*364 - 9*125 - 9*39 = 1,800</em>
Step-by-step explanation:
<em>Mental Calculation</em>
If we detect known patterns in the calculations, we could easily give their results without the use of calculators.
We are given the expression to evaluate:
9*364 - 9*125 - 9*39
The first thing to note is the 9 is a common factor of all terms, thus we take it out:
9*(364 - 125 - 39)
The negative numbers can be easily added
125
+ 39
------------
164
Now our expression is much easier:
9*(364 - 164)
The subtraction of 364-164 is 200, thus the result of the operations is:
9*200. We only need to recall 9*2=18 and add two zeros to get 1,800, thus:
9*364 - 9*125 - 9*39 = 1,800
Answer:
it was -5 and then it fell 8 degrees
-5 -8 = -13 degrees F
Step-by-step explanation:
Answer: 750 miles
Step-by-step explanation:
The gas mileage is 75 miles per 1/2 gallon of gasoline.
First find how many miles it can go on 1 gallon of gasoline:
= 75 ÷ 1/2
= 150 miles
If the scooter can go 150 miles on 1 gallon, the number of miles it will go on 5 gallons is:
= 5 * 150
= 750 miles
