256 is the value
REMEMBER PEMDAS
The height of the blue spruce was 45.
We find the mean by adding all of the data points and dividing by the number of data points. We will add the unknown value x and change the number we're dividing by to 7:
(160+320+100+110+200+220+x)/7 = 165
(1110+x)/7 = 165
Multiply both sides by 7:
1110 + x = 1155
Subtract 1110 from both sides:
x = 45
Answer:
Isolating a variable means rearranging an algebraic equation so that a different variable is on its own. The goal is to choose a sequence of operations that will leave the variable of interest on one side and put all other terms on the other side of the equal sign.
Step-by-step explanation:
Answer:
It would be True
Step-by-step explanation:
2+5x = -8
SUBTACT 2 on both sides and it would look like this:
5x = -8 - (2)
5X= -10
then DIVIDE 5 both side to get "X" ALONE,
x= -10/5
then divide -10 with 5
equal to:
x = -2
