I am not sure because there is no info about what is rate of decay
I assume if there is rate of decay is constant every hour then 0-2 it is
It 1/4th
So for 1st hour it is 933 gram
<span>(4x³-4+7x)-(2x³-x-8) = </span>4x³-4+7x<span> - </span>2x³ + x+8 = (4x³-2x³) + (7x+x) -4+8 =
= 2x³ + 8x +4
(4x³-4+7x)-(2x³-x-8) = 2x³ + 8x +4
Answer:
(5,15)
Step-by-step explanation:
We know that 225 = 15a + 10c, and he purchased a total of 20 tickets, so
a + c = 20, using this, we know that c = 20 - a, we can substitute this for c in 225 = 15a + 10c to get:
225 = 15a + 10(20 - a) =
225 = 15a + 200 - 10a
225 = 5a + 200
25 = 5a
a = 5
Now we substitute 5 for a:
225 = 15a + 10c
225 = 15(5) + 10c
225 = 75 + 10c
150 = 10c
c = 15
so a = 5 and c = 15, the solution is (5,15)
