Think: You're treating the numerator and the denom. in precisely the same way. In doing so you are NOT changing the value of the fraction, only the appearance.
Example: start with 2/3. Mult num. and den. both by 7: 14/21.
2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.
Answer:
A ) 6
Step-by-step explanation:
The formula for Average rate of change is:
Aroc = change in y / change in x.
Aroc = y2-y1 / x2 - x1
The first point will be (x1,y1), and second will be (x2,y2).
x1 is 0, and when the x value is at 0, the y value is at -7, so the coordinate point is (0, -7).
For the second point, x = 2, and the corresponding y value is 5. So you just simpliy plug everything into the formula to find AROC:
= 5 - (-7) / 2 - 0
= 12 / 2
= 6
You know how long each sheet is, and you need 8 of them. So, one sheet is 4/5 yards long, two sheets are yards long, and so on.
So, 8 sheets will be yards long.
To multiply two fractions, you simply multiply numerators and denominators among them:
Since , you have
Answer:
1 and 103/105
Step-by-step explanation:
Combine like terms: r+8r=9r. subtract 11 from both sides 9r=18. r=2
