Perimeter is the length of the whole outside of the shape, in this case the perimeter is 38. 7+7= 14 and 12+12= 24, 14+24= 38
Answer:
Let's denote:
Number or gifts cost 20 = x
Number or gifts cost 22.5 = y
Then, we have:
x + y = 10
20x + 22.5y = 217.5
=> 20(10 - y) + 22.5y = 217.5
=> 2.5y = 17.5
=> y = 7 (Number or gifts cost 22.5)
=> x = 10 - 7 = 3 (Number or gifts cost 20)
Hope this helps!

Answer:
-3/2, 1.25, |-9/4|, 2.5, 121
Step-by-step explanation:
Convert all numbers to a decimal
-3/2 = -1.5
|-9/4| = 2.25
2.5 = 2.5
121 = 121.0
1.25 = 1.25
Now put them in order from least to greatest.
-3/2, 1.25, |-9/4|, 2.5, 121
