A sled dog racer completed a race in 6 hours. Because of changes in the terrain, his average speed for the last 48 miles was twice as fast as his average speed for the first 12 miles. Which equation can be used to find r, his average speed in miles per hour, during the first 12 miles?
Answer:
1st choice
Step-by-step explanation:
Temp at noon was -0.6. It increases 1.2 until 3.
-0.6+1.2
gets colder 0.4, then 0.6.
-0.6+1.2-0.4-0.6
the only correct way to put this equation as one of the other answers is by putting it as -0.6+1.2+(-0.4)+(-0.6)
hope that helped!
So if you want to solve for c, the best thing to do is isolate the variable. So I personally don't enjoy dealing with fractions that much until the very end, so I am going to multiple the entire equation by
to eliminate the fraction. So now the equation is
. In order to isolate the c variable, subtract both sides by
, which makes it
. Now divide both sides by g,
. So that's what c equals in terms of f, d and g.
4.4 + (4 × 14 + 8.6)
Follow the order of operations (PEMDAS).
4.4+(56+8.6)
4.4+(64.6)
answer: 69
Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.
