Answer:
Step-by-step explanation:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Answer:
the third option
4, 2.75, 1.5, 0.25, -1, -2.25, ...
Step-by-step explanation:
the first value in the sequence is 4.
that eliminates already answer options 1 and 2.
and the values are going down, as we continuously subtract 1.25 from the previous sequence number.
but answer option 4 shows a sequence, where the values go up.
so, only option 3 remains and is correct
4-1.25 = 2.75
2.75-1.25 = 1.5
1.5-1.25 = 0.25
0.25-1.25 = -1
...
Answer:
$2009
Step-by-step explanation:
125+345+21=491
2500-491=2009
1/2•(2p-6)(p+1)
1/2•(2p^2+2p-6p-6)
1/2•(2p^2-4p-6)
p^2-2p-3
