Answer: B Exactly one solution
Step-by-step explanation:
5x+8-7x=-4x+1
-2x+8=-4x+1
-2x+4x=-7
2x=-7
x=-7/2
The first step in isolating z would be multiplying both sides by 4 to cancel out the fraction
after that you have
4x = 2y - z
subtract 2y
4x - 2y = - z
divide both sides by -1 to completely isolate z
-4x + 2y = z should be your answer
Answer:
12 - (-6)
Step-by-step explanation:
11 - (-5) = 11 + 5 = 16
-7 + (-3) = -7 - 3 = -10
12 - (-6) = 12 + 6 = 18
-9 + -9 = -9 - 9 = -18
0.1666 that is the answer
P(p)=number of purple gumballs divided by total number of gumballs
P(p and p)=P(p)*P(p) so this is without replacement so we get:
P(pp)=(24/100)(23/99)=552/9900
P(pp)=46/825 (≈5.58%)
