Answer:
3/2
Step-by-step explanation:
divide 33 by 22, you get 1.5
3/2 is 1.5 so ya
Let a=number of pens and b=number of pencils.
8a+7b=3.37; 5a+11b=3.10.
To eliminate a variable multiply the first eqn by 5 and the second by 8:
40a+35b=16.85, 40a+88b=24.80.
Subtract these equations: 53b=7.95, b=$0.15. So 5a=3.10-1.65=$1.45, a=$0.29.
Pens are $0.29 each and pencils $0.15.

Answer:
Step-by-step explanation:
Remark
If you find < 3 first, that will give you angle 5 by alternate interior angles. <5 and <7 are equal by vertically opposite angles.
Solution
<3 + <2 = 180o these two angles are on the same straight line.
<3 + 83 = 180o Subtract 83 from both sides
<3 = 180 - 83
<3 = 97
As per the remark <3 = <5 by alternate interior angles.
<5 = 97
<7 = 97 Vertically opposite angles are equal
Note
There are 4 angles that are equal to 83 and 4 angles that are equal to 97
83: angles 2 4 6 and 8
97: angles 1 3 5 and 7
No other values for this diagram are possible and these are always the result.
