90 = 30+10+3x
This equation shows that all the prices of the the bag, eraser, and pencils equals $90. So now all we have to do to find the price of a pencil is solve the equation.
First add the 30 and 10 together.
90 = 40+3x
Then subtract 40 from each side
50 = 3x
Lastly divide each side by 3
x = 16.67
The price per pencil is $16.67
Hope this helps!
Answer:
9.7
Step-by-step explanation:
tan=opposite/adjacent
tan=9/adjacent
tan 43=9/x
x tan 43=9
0.9325x=9
0.9325x/0.9325=9/0.9325
=9.65
hence;
x=9.7
