Answer:
-17
Step-by-step explanation:
3x-7=4x+10
Add 7 to both sides & simplify
3x-7=4x+10
+7 +7
3x=4x+17
Subtract 4x from both sides & simplify
3x=4x+17
-4x -4x
-x=17
*Negative x equals -1*
Divide both sides by -1 & simplify
Answer:

Answer: B. one-third
Step-by-step explanation:
Probability of picking a red marble, P(R) = 1/6
Probability of picking a yellow marble, P(Y) = 1/2
Therefore, the probability of picking a blue marble will be:
= 1 - (P(R) + P(Y))
= 1 - (1/6 + 1/2)
= 1 - (4/6).
= 1 - 2/3
= 1/3
The probability of picking a blue marble will be one third
