The pattern for first and second arrangement:
3 + 9 + 8 - 6 =14
10 + 2 + 7 - 3 = 16
Third arrangement:
11 + 8 + 17 - 4 = 32
Answer: 18.75 inches
Step-by-step explanation:
Let the height of the model be represented by x. Therefore, based on the information given in the question, we can form an equation which will be:
3/x = 32/200
Cross multiply
32 × x = 200 × 3
32x = 600
x = 600/32
x = 18.75
Therefore, the height of the model is 18.75 inches
Uhh... is this the full problem because this looks like this is half a problem.
Answer:
D
Step-by-step explanation:
-1.5(-6m+8n) = 9m-12n
3(3m -4n) = 9m - 12n
9m -12n = 9m -12n
-6(-1.5m +2n) = 9m - 12n
-2(-4.5m+ 4n) = 9m - 8n
