PV = k
divide P from both sides
V=k/P
Answer:
B) 1296 D) 729
Step-by-step explanation:
It's pretty straight forward, just put the values into your calculator. The question is asking to evaluate instead of simplifying, so this works. If you don't have a calculator, here are some tricks. Do them step by step in your head slowly if you have to, for fractions do them alone, and then divide them. Also in D, don't let the second value of (3)3)0 scare you, any exponent with a 0 in it is automatically 1! Hope I could help.
Answer:
x = -4
Step-by-step explanation:
I'm assuming we solve for x, so Let's solve for x!
First, combine like terms.
4x + 12 = -4
Now subtract -12 from each side.
4x = -16
Now, divide by 4 from each side.
x = -4
Total boys = 10 + 7 +10 + 9 = 36
Probability of picking a senior = 9/36 , reduces to 1/4
Total girls = 8 + 11 + 9 + 7 = 35
Probability of picking a senior = 7/35, reduces to 1/5
Probability of picking both multiply the probability of each by each other:
= 1/4 x 1/5 = 1/20
Answer is D.
Combine like terms.
2x + 6 + 6x - 1
8x + 5
