10) because of the alternative exterior angle theorem angle 2 is the same as angle 8 and because of the vertical angles congruence theorem angles 2 and 4 are also the same so if angle 2 is the same as both 4 and 8,
then x=5 because 4x+57 =77
subtract 57 from both sides and 4x=20
divide both sides by 4 and x equals 5
Answer:
x=35
Step-by-step explanation:
3x+3=108
3x=108-3
3x= 105
x= 105/3
x=35
7x (13x^2 - 8) = 91x^3 - 56x
For : " 2 magazines weigh 7/8 pounds what is the unit rate for pounds per magazine " The answer is : Each magazine weighs an overall total of 3.5/8 pounds.
You would multiply by the reciprocal (flip the fraction)
5/3 * 24 = 40
b = 40
