Answer:
x = -9/2
Step-by-step explanation:
Substitute y = -6 in the second equation.
y = 4x + 12
-6 = 4x + 12
Subtract 12 from both sides.
-18 = 4x
Divide by 4.
-9/2 = x
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.
Answer: I really don't know how to do this sorry
Step-by-step explanation:
In order to find the area, you multiply the width (7), height (6) and length (12). But the problem states that the height has changed from 6 to 6 minus3, which would be 3. So you multiply 3, 7, and 12.
