Answer:
x = -1
Step-by-step explanation:
2x + 3(2) = 4
2x + 6 = 4 Multiply 2 and 3 to get 6.
2x = -2 Subtract 6 from both sides to isolate 2x.
x = -1 Divide both sides by 2 to find x.
Answer:
Step-by-step explanation:
y = - 9
y^2 = (-9)^2 = 81
AND
z = 0.7
z^2 = (0.7)^2 = 0.49

5x4 = 20
20x10 = 200
200x200x200x200 = 1600000000
So 8 zeros.
In order the numbers are 20, 29, 32, 37, 42.
So that means the median is 32. In order for the median to stay the same one of the three data values must be 32 as well as adding a number to each side of the ends. One 32 or less another 32or more.
The mean right now is: 20+29+32+37+42=160 and there are 5 values.
Mean: 160/5=32
For it to increase by 10 it has to be 42.
extra 3 numbers I used were 31, 32, & 113 (those are your answer)
