Step-by-step explanation:
Mean=sum of terms/ number of terms
22+23+25+17+18/5
105/5
21
Finding the age of the sixth person
105+x/6=24
105+x=24x6
105+x=144
x=144-105
x=39
The formula would be set up as ratios (or fractions). The first ratio is 6:5, which in total is 11. There were 6 yes out of 11, so the fraction = 6/11.
The second fraction has a total of 5918, however you do not know the amount of yes votes, so the variable placeholder will be called "x".
The final formula would be:
6/11 = x/5918
You do cross multiplication and you get:
11x = 35508. You divide both sides, and you get x = 3228.
Because x is the placeholder for the amount of yes votes, and x = 3228, the amount of yes votes is 3228

Assuming that the sum of all the angles must equal 180°
180 - (27+10) = k
180 - 37 = k
k = 143°
Answer: 39
Step-by-step explanation:
180-(39+102)
180-141
39
Answer:
y= 12
Step-by-step explanation:
2/3 y + 7 = 15
Subtract 7 from each side
2/3 y + 7-7 = 15-7
2/3 y = 8
Multiply each side by 3/2 to isolate y
3/2 * 2/3 y = 3/2 * 8
3/2 * 2/3 y = 3 * 4
y = 12
