First you want to find out how many marbles you start with so it'd be 8+7=15. You start with 15 marbles. If you randomly drew a blue marble, it'd be 8:15 and if you drew a yellow marble without replacing the blue one, it'd be 7:14 or 50-50 chance.
A) 4*N -Q = 0
B) .05N + .25Q = 2.10
Multiply B) by 4
B) .2N + Q = 8.40 Adding this to A)
A) 4*N -Q = 0
4.2N = 8.40
N = 2 Nickels
Q = 8 Quarters
Answer:
g(2a) = 16a^2 - 6a + 2
Step-by-step explanation:
Replace every occurrence of x in g(x) = 4x^2 – 3x + 2 with (2a); it's best to use parentheses here.
Then g(2a) = 4(2a)^2 - 3(2a) + 2
= 4(4a^2) - 6a + 2
= 16a^2 - 6a + 2 (answer)
Answer:The answer is 2 and 1/5 = 4x - 4/5 = 3/4 pound.
So your answer would be C

9m = 4.5
divide by 9 for 9m and 4.5
9m/9= 4.5/9
m= 0.5
3v= -105
divide by 3 for 3v and -105
3v/3=- 105/3
v= -35
17m = 85
divide by 17 for 17m and 85
17m/17= 85/17
m= 5
Answers: 0.5,-35 and 5
