Answer:
1.No- that just means that the numbers on that side are smaller
Step-by-step explanation:
1. Perimeter
22a + 2(6a + 8) -4 = p
[I got 22a from 12a + 10a]
2. If p = 250, what is a?
22a + 2(6a + 8) - 4 = 250
Distributive property
22a + 12a + 16 - 4 = 250
Add like terms
34a + 12 = 250
Subtract 12 by both sides
34a = 238
Divide 34 by both sides
a = 7
If we are to consider the number of slices of bread first,
number of sandwiches = (28 slices of bread)(1 sandwich/ 2 slices of bread)
number of sandwiches = 14 sandwiches
If we are to consider the number of slices of cheese
number of sandwiches = (45 slices of cheese)(1 sandwich / 3 slices of cheese)
number of sandwiches = 15 sandwiches
Since, 14 is smaller than 15 then, 14 is the answer.
<em>Answer: 14 sandwiches</em>
