Answer:
s = -6.7
Step-by-step explanation:
- 16.68 + 1.8s + 2.2 = 3s - 6.4
- 16.68 + 2.2 + 1.8s = 3s - 6.4
- 14.48 + 1.8s = 3s - 6.4
Collect like terms
Note: crossing over equals to, the sign will change
Hint: either from
- to +
Or
+ to -
-14.48 + 6.4 = 3s - 1.8s
-8.08 = 3s - 1.8s
-8.08 = 1.2s
Divide both sides by 1.2, to get the value of s
-8.08/1.2 = 1.2s/1.2
-6.7 = s
s = -6.7
Answer:
5.5 feet

There is no answer? So how am I supposed to answer it?
Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.
