(2x-y)+(3y-x) = 2y+X = 25
25 = 2:1 = 2Y:X
25/3 = 25/3
25/3 * 2 = 50/3 = 2y
x = 25/3
y = 25/3
Hope this helps! :)
Answer:
(3p-5 )(q+2)
Step-by-step explanation:
3pq + 6p - 5q -10
3p (q+2) -5 (q+2)
(q+2) (3p-5)
That is your complete answer
The best thing to do here is to find ten percent, and then double it.
To do this, you divide the number you have by 10.
65.00/10= 6.50
Therefore, you've now got to multiply this by 2.
6.5*2= 13
Therefore, Kim saved $13 on the price of the dress.
Hope this helps :)
For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.
He will earn $427.50 because $4.27 times 90 equals $427.50
