A.) equal
B.) 10.4
C.) 6.549
D.) 30.778
Answer:
a ≠ 2b
Step-by-step explanation:
The given expression is
Simplifying it, we have
For the above fraction to exist, the denominator must not be equal to zero.
i.e, a-2b ≠ 0
=> a≠2b
∴ The algebraic fraction exists when a≠2b.
Answer:
It will take the worm 7 days to get to the top of the well.
Step-by-step explanation:
the well is 37 feet deep
the worm climbs up 7 feet, but loses 2 feet through the night
That means the worm only really climbs 5 feet a day.
So, if you subtract 5 from 37, 6 times, you'll get 7 feet left to go. And sense the worm climbs 7 feet a day, the last day the worm will climb his way to the top without slipping back down.
Hopefully this makes sense.
Answer:
When A and B are not both zero, the graph of Ax + By = C is always a line. The graph of Ax + By = C, where A and B are not both zero, is a line. Divide both sides by B. Because the form Ax + By = C can describe any line, it is called the standard form of an equation for a line.
Hope this helps you!
Answer: A. 40%
Step-by-step explanation:
to find the percentage decrease, first you have to subtract $6,300 from $10,500, which equals $4,200. This is the amount decreased from the price of the car. Then, to find the percentage that $4,200 is to $10,500, you have to divide 4,200 by 10,500. This should give you 0.4, the percentage is this number multiplied by 100. This should give you the number 40, which means that the percentage decrease of the price of the car; 40%.
