Answer:

Step-by-step explanation:
Hello There!
The angle labeled 6x is a right angle
If an angle is formed using the diameter of a circle then the opposite angle of that side is a right angle
So 6x = 90
isolate the variable
divide each side by 6
90/6= 15
6x/6=x
we're left with x = 15
<span>Neon is heavier than helium and does not react with other elements. This is because Neon is a noble gas and is very stable because its outer electrons are filled.</span>
Expenses: $6.00 + $4.50 + $2.50 = $13.00
income = balance + expenses
income = $3.52 + $13.00
income = $16.52
Ok so Jessica bought M pens, which cost $6.70 each.
She also bought 4 fewer pencils than pens, or (M-4) pencils, at $3.50 each.
So in total, she spent:
6.7M + 3.5(M-4)
= 6.7M + 3.5M - 14
= 10.2M -14
So she spent $(10M - 14) on pens and pencils.
Hope this helped
