12 packets in all
7 packets, 9 crayons
7×9=63 crayons
5 packets, 10 crayons
5×10=50 crayons
In all tells you to add all the previous numbers up
50+63= 113
The teacher bought 113 crayons in all.

Answer:
height of the utility pole = 12 meters
Step-by-step explanation:
It is simple application of Pythagoras theorem.
In the given case, Length of cable (Hypotenuse) H = 13 meters, distance between base of pole to the point on the ground(Base) B = 5 meters and height of pole ( Perpendicular) P form a right angle triangle.
The applying Pythagoras theorem.
H^2 = P^2 +B^2
⇒ P^2 = H^2-B^2 = 13^2-5^2 = 144
⇒ P = 12 meters
hence, height of the utility pole = 12 meters
There are four coefficients in that expression, so the coefficients are 1/3, -18, 9, and -2.
