Use the least commom denominator of 10 and 15 to solve 2/10+ 7/15
Juli2301 [7.4K]
The least common denominator of 10 and 15 is 30. It's easiest to use trial and error to find the LCD. In this case, just multiply both numbers by 2 and see if that works. Since 15 doesn't go into 20, I tried multiplying 15 by 2  instead, and got 30, which is divisible by 2. If that doesn't work, move on to multiplying them by 3, then 4 four, and so on. However, in this case, it did work, so, since you multiplied 15 by two to get 30, multiply 7 by two to get the fraction 14/30. Then, since you multiplied 10 by 3 to get 30, multiply 2 by 3 to get 6/30. Then, add the two together to get 20/30 and simplify the fraction to 2/3. 

2/10 + 7/15   Given.
6/30 + 14/30   LCD.
20/30   Add.
2/3   Simplify.

E graph shows the altitude of a helicopter over time.
DaniilM [7]

Let

x-------> the time

y-------> the altitude of a helicopter

Step 1

<u>Find the slope of the line</u>

we know that

the slope m of the line between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

we have

(x1,y1)=(0,10,000)\\(x2,y2)=(15,4,000)

substitute in the formula

m=\frac{(4,000-10,000)}{(15-0)}

m=\frac{(-6,000)}{(15)}

m=-400\frac{feet}{minute}

therefore

<u>the answer is the option </u>

The slope is -400 . This means that the helicopter descends 400 ft each minute.
