Where Z is set of integer.
Answer:
D. 75(5r+3d+4f) and 75(5r)+75(3d)+75(4f)
For this equation we are factoring. When you do this. You get the answer of:
(-3x²+8x-7)
Machine A:
60 / 10 = 6 - 10 minute segments per hour
7 x 6 = 42 - parts per hour
42 x 12 = 504 - parts made on Monday
Machine B:
60 / 15 = 4 - 15 minute segments per hour
16 x 4 = 64 - parts per hour
64 x 10 = 640 - parts made on Monday
504 + 640 = 1144 - parts made by the two machines on Monday
Hope this helps!! :)
Answer:
A or the first answer is correct
Step-by-step explanation:
3650 - 2000 = 1650
1650 / (divided by) 150 = 11
you can also check your work by doing 150 *(times) 11 = 1650
1650 + 2000 = 3650
