Answer: R = 37.5 miles per gallon.
Step-by-step explanation:
Sandras truck need one gallon to drive 25 miles, then the rate of Sandra's truck is 25 miles per gallon.
Her sister's car can travel 12.5 more miles with one gallon, so the car travels
25mi + 12.5mi = 37.5 miles with one gallon, the rate is
R = 37.5 miles per gallon.
Now, with that number you can multiply the amount of gallons that you have and you will obtain the total amount of miles that you can travel with that amount of gallons.
Answer:
3.
Step-by-step explanation:
If Andre's representation is correct, that the slope is 3. The question is confusing me a bit, because it isn't very clear, but Andre's Representation is in Point Slope Form, (y=mx+b) where m represents the slope. So again, if Andre's representation is for the graph and is correct, the slope is 3.
Answer:
No real solutions;
Step-by-step explanation:
The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;
- Take the square root of both sides
==================================================================
As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit (
) represents (
).
==================================================================
- Add (3) to undo the (-3)
- Divide by (2) to remove the coefficient of (2x)
