Answer:
2/3x - 3 = 5
Step-by-step explanation:
Let x be the number
2/3x - 3 = 5
Add 3 to each side
2/3x-3+3 = 5+3
2/3x = 8
Multiply each side by 3/2
3/2*2/3x = 8*3/2
x = 12
Answer:
(number - mean)/standard deviation.
Plug in the 78 for the number, the 84.5 for the mean, the 3.1 for the standard deviation.

Answer:Scalene Triangle
Step-by-step explanation:
In a scalene triangle,all sides are not equal
Answer:
area of trapezium: -
formula...
½(sum of parallel sides)×height=area
=>240=½(12+x)×12
=>240=(12+x)×6
=>240=60+6x
=>6x=240-60
=>6x=180
=>x=180/6
=>x=30cm
therefore, the value of x is 30 cm.
