Idk what it is bro what is it
1/8 because if I choose a black one first then put it back there isn't a 50% chance
The answer would be:
d. 0, $12.40, $24.79, $37.19, $49.58; The practical range of this function is 0≤f(g) ≤49.58
The number of gallons needed is the value of g variable, so you need to put the variable value into the equation. The calculation would be:
f(g)= 2.479g
f(0)= 2.479(0)=0
f(5)= 2.479(5)=12.395= 12.40
f(10)= 2.479(10)=24.79
f(15)= 2.479(15)=37.185= 37.19
f(20)= 2.479(20)=49.58
The range of the function would be more than(≥) 0 but less than(≤) 49.58. If you put it together, the sign would look like 0≤f(g)≤49.58
1) 4x + 3(x-9) = 19
or, 4x + 3x - 27 = 19
or, 7x = 19+27
or, 7x = 46
or, x = 46/7
◆ x = 6.57
2) 2(x-4) + 5x = 3
or, 2x - 8 + 5x = 3
or, 7x = 3+8
or, x = 11/7
◆ x = 1.57
3) 60 = 8y - 3(y-10)
or, 60 = 8y - 3y + 30
or, 60 - 30 = 5y
or, y = 30/5
◆ y = 6
4) 40 + 3c = 3 + 9(c-2)
or, 40 + 3c = 3 + 9c - 18
or, 40 + 3c = 9c - 15
or, 9c - 3c = 40 + 15
or, 6c = 55
◆ c = 9.166
I hope you understand..
Thank you...♥♥
♥ 8+7=15
♥ Therefore he started out with $15
♥ I know it's $15 because it says he paid $8 but now he has $7
♥ Therefor if we added we could check to see if its correct and it is, also if we so 15-8 we get 7.
♥ So your answer is $15<span />
