Answer:
2.50$
Step-by-step explanation:
Time Distance Distance / Time
2hrs 90 miles 90 miles / 2 hrs = 45 miles / hr
3hrs 135 miles 135 miles / 3 hrs = 45 miles / hr
5hrs 225 miles 225 miles / 5 hrs = 45 miles / hr
6hrs 270 miles 270 miles / 6 hrs = 45 miles / hr
Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.
Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt
Constant of proportionality is k which is D/T
d = 45t
Answer: 90
Step-by-step explanation:
set: {1, 2, 3, 4, 5, 6, 7} = 7 numbers | 3 even
no element may be used more than once in a number = distinct elements
and the number must be even = must finish with a even number.
This way, we should start with the last number, which we have 3 possibilities.
Since we have 7 numbers in total, we have 6 options for the first one and then 5 options for the second one.
So, we have 6.5.3 = 90
Remember that the additive inverse are two equal numbers (or expressions) but with different signs.
We have then, that according with the coment below:
(3a2 - 5ab + b2) - (-3a2 + 2b2 + 8ab)
the additive inverse is:
(3a2 - 2b2 - 8ab) Note that is the same expression that
(-3a2 + 2b2 + 8ab)
but with different signs.
Answer:
the additive inverse of the polynomial being subtracted is
(3a2 - 2b2 - 8ab)
