Answer:
x=2
Step-by-step explanation:
18−7x=2x
Step 1: Simplif
18−7x=2x
18+−7x=2x
−7x+18=2x
Step 2: Subtract 2x from both sides.
−7x+18−2x=2x−2x
−9x+18=0
Step 3: Subtract 18 from both sides.
−9x+18−18=0−18
−9x=−18
Step 4: Divide both sides by -9.

Step 1: arrange the data points in order
12 14 24 30 35 40 42 50 53 Step 2 : Find the median.
median is 35. Step 3. divide the data points into two : left and right
of median
12 14 24 30 and 40 42 50 53
Step 4: find median of each12 14 24 30 : (14+24)/2 = 1940 42 50 53 : (42+50)/2 = 46
step 5. draw lines on the scale on the median, two other
medians and least and the greatest value
Answer is B.
Answer:
b
