( x + 1 )/ 3 = x + 2
Multiply 3 on both sides
x + 1 = 3x + 6
Subtract 6 on both sides
x - 5 = 3x
Subtract x from both sides
-5 = 2x
Divide 2 from both sides
x = -2.5
Answer:
94
Step-by-step explanation:
Its pretty simple,
The easiest way to find the missing number is to do 151-57, which = 94
Multiply straight across
5/1 * 3/4 = 15/4
now change it into a mixed number
3 3/4
<span>data: 2, 5, 9, 11, 17, 19
</span>
median is the middle number
median = (9+11)/2 = 10
mean = average
mean = (2 + 5 + 9 + 11+ 17 + 19)/6
mean = 63/6
mean = 10.5
