9 x 8 = 72
155 - 72 = 83
83 divided by 6 =13.8
So he has to make at least 14 deliveries in order to reach his goal.
Answer: C. 3, 11, 23, 31
Step-by-step explanation:
None of these can be divided by anything except themselves and 1.
Step-by-step explanation:
2112 + 2212 + 2312 / 4 leaves no remainder, as already the individual numbers could be divided by 4 without remainder.
2113 = 2112 + 1
2213 = 2212 + 1
so, we get a remainder of +1 and +1 for these 2 numbers, so we get in total a remainder of +2.
Answer:
0.75
Step-by-step explanation:
We do y/x to find out the Unit Rate.
So 1.2/1.6 = 0.75
<span>For the graph y = 1, the slope of a line that is perpendicular would be infinity because it lies vertically. The slope of the line parallel to it will have the same slope with y=1 which is zero because it lies flat or horizontally. Hope this answers the question. Have a nice day.</span>
