Step-by-step explanation:
So solve for q
first factor q out of the summation

now, determine what the summation is

its been a while since ive done summations so i dont remember any tricks but that summation is essentially equal to

or factored to be something like this

which i believe there's a formula for
regardless using a calculator, the summation turns out to be 4/3 i think
you should definitely double check this step
so replacing the summation for 4/3, the equation is now
q*(4/3) =8
pretty easy to solve from here
divide 4/3 to both sides to get q
any questions?

If an hour is 60 minutes, what we know is that 30 minutes is half. However, we must subtract 55 from 30 (In time)
To make this easier, subtract 55 by actual 30, and split 55 into 2 parts, the result of subtraction, and the other value, 30

Now, subtract.


If this is the case, the lesson must have started at 2:35 pm
The largest number of sweets that cannot be purchased exactly is 113.
The answer would be $1.75 (Rounded off to the nearest cent).
Substitute the given cost of each pint of fruit to the equation. Transpose and simplify, to get the price of a pint of veggies.
Given: <span>5v + 7f = 28.70; f = $2.85
Solution: </span><span>5v + 7(2.85) = 28.70
</span><span>5v + 19.95 = 28.70
5v = 8.75
v = 1.75</span>
