Answer:
102
Step-by-step explanation:
These angles are congruent due to corresponding angles thm
3x + 21 = 6x - 60
3x - 6x = -60 - 21
-3x = -81
x = 27
3x + 21
3(27) + 21
81 + 21
102
3- 2b +4 = 2-7b
3+4 = 2 - 5b
7 = 2 -5b
5 = -5b
-5b /-5 = -1
b = -1
First, you want to know the amount of ounces per pound. 1 pound has 16 ounces, so 2 pounds will have 32. Then, you want to take the amount of money you have and divide that by the number of ounces to get the 1 ounce cost. ( 13.98 divided by 32 = 0.4368 ) Finally, you want to multiply that 1 ounce number by 5, and you will get 2.184 or $2.18. ( or you can round up to $2.19 )
The answer is -56. For future problems, I highly recommend the calculator app “Desmos”, and writing the equation out in the calculator, and then replacing X values with the number (-8).
