Answer : 4
Explanation : you minus the 2 on both sides bc they have the same "last name" by doing this you get 12 on the left and elimination 2 on the right which leaves you with 12=3x. Divide 3 on both sides which 12/3 =4 and ur left with x. So the final equation is 4=x
It has rained 6 days out of 10 possible days ( 10 years = 10 first days of school)
The probability of rain would be the number of times it rained over the total number of days:
6/10, which reduces to 3/5 as a fraction or 60% as a percentage.
Answer:
v= 17
Step-by-step explanation:
Start with the given equation.
19v – 18 = 16 + 17v
Move -18 to the other side, and swap it's sign.
19v = 16 + 18 + 17v
Move 17v to the other side and swap it's sign.
19v - 17v = 16 + 18
Combine like terms.
2v = 34
Divide by 2v.
v = 17
