To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.
15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been
The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20
So take the 21 from before, and if you add -1, you get 20!
So, x= ➖1⃣!!!!!!! (That's a -1)
Answer:
x = 6/2 = 3
Step-by-step explanation:
This is a dilation. A dilation is a change in size, whether it is an enlargement or reduction.
The scale factor is how much the enlargement is.
The side of Figure A is 2.
So we must multiply 2 ⋅ 1 1/2.
2 ⋅ 1 1/2 (3/2) = 6/2
6/2 is equal to 3.
Therefore, the value of x in Figure B is 3.
A 4/52
B 26/52
C 13/52 of course in simpilest form though.
