16 + (-3) = (n+3) + (-3)
N = 13
Answer:
If a plank which is 10 feet long is cut into two pieces and if one piece is x feet long,
Then the other piece will be (10 – x) feet long.
Here the value of the one piece is given as ‘x’ value
so the represent of the length of the other part will be (10 – x ) feet

Answer:
function
Step-by-step explanation:
hahahahahahahbasta yan ata ang sagot
In this problem, we have to find the factor which will
make (1 / 10) equal to (2 / 5). Therefore we can write it as:
x (1 / 10) = 2 / 5
where x is the number of people who ate the blueberries
x = (2 / 5) / (1 / 10)
x = 4
<span>Therefore 4 people ate the blueberries.</span>
Answer:
20 miles with an error margin of ± 8 miles
Step-by-step explanation:
The margin of error of a result is the range in which an error can vary. To find the margin of error between both distances we have to
28-12 = 16, that is, the variation of the result has a range of 16 miles. So we will look for the midpoint of both distances
(X2-X1)/2+X1=(28-12)/2+12=16/2+12=8+12=20
So from this midpoint the value can vary between 8 points below and 8 points above that would cover the difference of 16 miles that we observed at the beginning
In this way, the correct answer is 20 miles with an error margin of ± 8 miles
Done
