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
The answer is 32 because there are 5 in the actual one
Answer:
<em>x - y = 2</em>
Step-by-step explanation:
First of all, you would combine like terms, giving you 4x - 4y + 1 = 9.
Next, subtract the numbers, which gives you 4x - 4y = 8.
Finally, divide both sides by 4, which will come to the conclusion of x - y = 2, the simplest form of which this equation can be broken down to.
$5 because you do 50 times 20% (get 10) subtract 10 from 50 (50-10). You’d get $40! You have $35 so therefore, $40-$35=$5!
