Answer:
x = 1/3
Step-by-step explanation:
Perform the indicated multiplication:
Clear out the fractions. The LCD here is 12, so multiply both sides by 12, obtaining:
3(3x - 1) = 24x - 8, or
9x - 3 = 24x - 8
Combining like terms, we get 5 = 15x, so that x = 1/3.
Answer: The last option is the answer
3(3 root 3)-3(3 root 2)
Answer:
Step-by-step explanation:
the slope is 4
y int is 1
answer:
it is not proportional.
step-by-step explanation:
14-10.50=3.5
17.50-14=3.5
24.50-17.50=7
in order for it to be proportional, they would all have to equal the same number and since in this case, they don't it is non-proportional
hopefully, this helps :)
have a nice day !!
i'm extremely sorry i couldn't help sooner :(
Answer:
187.5 doughnuts (about 188)
62.5 candy bars (about 63)
Step-by-step explanation:
So the proportion of middle schoolers who prefer doughnuts is p = 9/12. That means the proportion of middle schoolers who prefer candy is 1 - 9/12 = 3/12.
The number of middle schoolers is n = 250.
Let X represent the number of doughnuts you need. The expected number is E(X) = np, so multiply them together:
E(X) = np
E(X) = 250 * 9/12 = 187.5 doughnuts
Let Y represent the number of candy bars you need. The expected number is E(Y) = np, so multiply them together:
E(Y) = np
E(Y) = 250 * 3/12 = 62.5 candy bars
