Answer:
31 yards of ribbon
Step-by-step explanation:
Of after purchasing the ribbon in bulk she has $21.28 left from her initial $25 it would mean that she spent $3.72 in total.

So in spending $3.72 on ribbons we can find how much yards she bought by seeing how many times 12 cents can go into the $3.72 (the amount of money she spent).

Answer:
B
Step-by-step explanation:
It tells you
B)decreases by one; arrow length decreases by 1/3
Answer: H=12 and B=8
Looking at the problem, you are given the area, <em>a</em> , and told the h is 4 meters longer than <em>b; </em>in other words, <em>h</em>=<em>b</em>+4.
Since <em>a=</em>1/2<em>bh</em>, you can replace <em>a</em> with 48. Also, since <em>h</em> is <em>b</em>+4, you can replace that as well. You'd end up with this equation:
48=1/2b(b+4)
1. Seeing that 48 is 1/2 of <em>b,</em> you know that you have twice the value of 48, or 96. So, you can put that 96=<em>b(b+4). </em>
2.<em> </em>Now, thinking through factors of 96- 1 x 96, 2 x 48, 3 x 32, 4 x 24, 6 x 16, or 8 x 12, the only pair in which <em>h </em>is b+4 is 12 x 8.

Do you need an equation?
y=2x+10
2x represents each hour, 10 represents renting fee
