The number of new calculators tested was 50 . . . 8 were bad and 42 were good.
The ratio of defective ones to new ones tested is 8:50 or 4:25 or 16% .
Area=Pi r squared
Pi*12*12
452.39cubic cm
To the nearest tenth =452.4cubic cm
(20 + 12) - 8, since the question states n is EIGHT less than the sum of 20 and 12.
= 5x + 35 = -3
- 35 = -35
5x = -38
/ 5 = / 5
x = -7.6
Answer: B: (y + z = 6) × -5
Step-by-step explanation:
if you multiply 'y' by -5 it turns into -5y. Therefore when you add -5y and 5y together, you get 0y which is what you want when eliminating the y-term.
