Answer:
The answer would be A, B, and C.
Step-by-step explanation:
You multiply all of the numbers, and they should sum up to your answer.
3+4x=15
4x=15-3
4x=12
x=12/4
x=3
The check is:
<span>If x=3 then, </span>
3+ (4 X 3)=15
<span>3+12=15</span>
P(cube lands on 4 = 1/6
P(coin lands on heads) = 1/2
P( both) = 1/6 * 1/2 = 1/12 <===
The answer is has to be D
Answer:
x = 2
Step-by-step explanation:
log27(x + 7) - log27(x - 1) = ⅔
log27[(x + 7)/(x - 1)] = ⅔
(x + 7)/(x - 1) = 27^⅔
(x + 7)/(x - 1) = 9
x + 7 = 9(x - 1)
x + 7 = 9x - 9
8x = 16
x = 2
