Answer:

Step-by-step explanation:
Firstly, move over the negative 3/4 fraction (don't forget to swap the operation i.e subtract to add):

Now, to add the two fractions, simply multiply the numerator and denominator by 3:

Now add this to the other fraction:

This can be simplified down by dividing both the numerator and denominator by 4:

Which now simplifies the original equation to:

Remove the y out of the fraction:

Now multiply both sides by 8:



Hope this helps!

That would a set of 5 numbers in ascending order with 4 being the middle one and the other 4 being the highest possible So it is
2, 3, 4, 9, 10
Mean is 28/5 = 5.6 answer
( I am assuming that each number is different)
Of duplicates is allowed then its 4 4 4 10 10 whose mean is 6.4
Answer: $20,790
Step-by-step explanation:
The sales revenue increased by 5% from 2018 to 2019.
The sales revenue that was increased from in 2018 is $19,800 which means that the 2019 sales revenue is 5% more than $19,800.
To find the sales revenue in 2019, do the following:
= 19,800 + (19,800 * 5%)
= 19,800 + 990
= $20,790
The equation should be
j = 30 + 3a
j + a = 210
Solving the equation
j + a = 210
(30 + 3a) + a = 210
30 + 4a = 210
4a = 180
a = 45
j = 30 + 3a
j = 30 + 3 × 45
j = 30 + 135
j = 165
