Answer:
-12
Step-by-step explanation:
Let the number be A
Given if you divide the sum of six and the number A by 3 , the result is 4 more than 1/4 of A
That’s
6+A/3 = 4+1/4 of A
6+A/3 = 4+1/4 x A
6+A/3 = 4+A/4
Cross multiply
4(6 + A) = 3(4 + A)
Distribute
4 x 6 + 4 x A = 3 x 4 + 3 x A
24 + 4A = 12 + 3A
Subtract 24 from both sides to eliminate 24 on the left side
24 - 24 + 4A = 12 - 24 + 3A
4A = -12 + 3A
Subtract 3A from both sides so the unknown can be on one side
4A - 3A = -12 + 3A - 3A
A = -12
Check
6+(-12)/3 = 4 +(-12)/4
6 -12/3 = 4 -12/4
-6/3 = -8/4
-2 = -2
Answer:
To find the mean, multiply the values by frequencies, add the subtotals, and divide by the total number of the frequency. Median : To find the median, calculate a running total of the frequencies, which is half the total, it contains the median that corresponds to the value.

Answer:
3321
Step-by-step explanation:
Before I distribute, I solve the inside first:
2/3[8(3)^2+6]
2/3[8(9)+6]
2/3[72+6]
2/3[78]
2*26= 52 is the answer
another way:
2/3[8(3)^2+6]
2/3[8(9)+6]
2/3[72+6]
(2/3)*72+(2/3)*6
2*24+2*2
48+4= 52
okay so you just plug in the x and ys. x is the first number, y is the second. then you just do them all out
