Answer:
y=x+15
Friend swims 40 minutes
Step-by-step explanation:
We re told that you want to swim 15 minutes <em>longer</em> than your friend. In word problems, longer or more always means addition. This means we will add 15 minutes to your friend's swim time (x) so we can figure out how long you swam (y).
This gives us the equation: y=x+15
Part two:
We know that you swam 55 minutes. This means y=55.
55=y=x+15
55=x+15
Now we want to get x alone, or isolate it. We can do this by subtracting 15 from both sides.
55-15=x+15-15
15-15= 0 and 55-15= 40
40=x
Thus your friend swam 40 minutes
(Remember that whatever you do to one side of the equation, you have to do to the other. If you add 2 to the left hand side, you have to add 2 to the right hand side. If you, like we did above, subtract 15 from the right, you have to subtract 15 from the left too)
Answer: max
Step-by-step explanation:
Second choice- multiply by 12
Answer: The Crimson Bot clicks 26 times in _2.5_ sec,
To find the time, Invert the Unit rate to Seconds per Click, times the number of clicks.
Step-by-step explanation:
Find Seconds per click by dividing 1/10.4
That is ⁵/₅₂ or 0.09615384615 seconds per click
Multiply by 26 clicks. ⁵/₅₂ × 26 = 2.5
Or invert the unit rate and multiply by the given number of clicks:
1/10.4 × 26 =
