Answer:-126f-108
Step-by-step explanation:
9(-9f - 2)-9(5f +10)
-81f - 18 -9(5f + 10)
- 81f - 18 - 45f -90
- 126f - 18 - 90
-126f -108
which give you the answer -126f - 108
Answer:
x = 2.25 y = 0.75
Step-by-step explanation:
2x = 9.5- 5
2x = 4.5
x = 4.5 ÷ 2
x = 2.25
know we now what is x so in the second one we evaluate x
3(2.25) + 5y = 10.5
6.75 + 5y = 10.5
5y = 10.5- 6.75
5y = 3.75
y = 3.75 ÷ 5
y = 0.75
that's it !
if you want to check your answer you can evaluate x and y so it will be like
2×2.25 + 5
= 4.5 + 5 = 9.5
and
3× 2.25 +5×0.75
= 6.75 + 3.75 = 10.5
It is NOT possible to determine the missing value from the given data.
<h3>Mean and Median</h3>
Mean is the average of a number of data while the median is the number at the middle of the given data.
- For a given data with a missing value, we can only find the missing value by calculating the mean of the data and equating the given mean.
Hence from the given data, it is NOT possible to determine the missing value from the given data.
