The next number would be 4 because you add 1, then, subtract 2, add 3, subtract 4, meaning you would add 5 to -1 and get 4
The answer is 4
Answer:
5.0-2.5=2.5
Step-by-step explanation:
<span>(38-63)×6÷Z
=</span><span>(38-63)×6÷84
=-25</span>×6÷84
=150
=1 66/84
= 1 33/42
Answer:
D.
Step-by-step explanation:
There is nothing in the figure to indicate the triangles are isosceles. This eliminates answer choices A, B, C.
Answer choice D is a required step in the proof, but only gets part of the way. The triangle similarity means ...
SQ/PQ = TQ/RQ
From here, you need to decompose each of the sides PQ and RQ into parts. Then you can get to the desired relationship.
(PQ -PS)/PQ = (RQ -RT)/RQ . . . segment sum theorem
1 - PS/PQ = 1 -RT/RQ . . . . . . . do the division
-PS/PQ = -RT/RQ . . . . . . . . subtract 1 (subtraction property of equality)
PS/PQ = RT/RQ . . . . . . . . multiply by -1 (multiplication property of equality)
11. 50*17 answer divided by $356
12.$21*3 then get the answer
13. Do $20*15
14.$2.20*10
15.5*15 then get the answer
Hope I helped
