Answer:
The model is shown in the attached picture. The solution is 10.
Step-by-step explanation:
There are two way of showing a model for 2×5
- The tape diagram has 2 equal-sized parts of 5
- The tape diagram has 5 equal-sized parts of 2
Both models give the same solution:
- 5+5=10
- 2+2+2+2+2=10
In the attached picture we can show two types of diagram.
Answer:
c/-9+6=14
c/-9=14-6
c/-9=8
c=8×(-9)
c= -72
Therefore the answer is (b)
| 42 | The absolute value of forty two
Answer:
D: 2/4
Step-by-step explanation:
Usually when we talk about a point partitioning a segment, we are interested in the ratio of the first segment to the second:
BC : CD = 2 : 2 = 1 : 1
Since this is not an answer choice, we need to "reverse engineer" the answer list to see if we can find an answer that corresponds to a reasonable interpretation of the question.
__
None of the segments is 3 units long, so neither of answer choices A or B makes any sense.
While segment BD is 4 units long, there is no segment that is 1 unit long, so answer choice C makes no sense, either.
There are segments that are 2 units long and a segment that is 4 units long, so if we interpret the question to be "what is the ratio of BC to BD?" then answer choice D is appropriate.
