3 feet = 1 yard
324 inches = 27 feet = 9 yards
10 yards = 1 package of fringe
10 yards - 9 yards = 1 yard or 3 feet
The answer is 10% if There is 40% six graders and 20% seventh graders then you need 10% more to make 100% so it’s 10% eighth graders
<h3>
Answer: Choice A) y = -10x^2</h3>
Explanation:
The equation y = ax^2+bx+c has the value of 'a' determine how wide or narrow the graph is. The closer 'a' is to zero, then the wider it gets; while the further 'a' is from 0, the narrower it gets.
What we need to do is look for equations in which the 'a' value is furthest from 0. In this case, it's with y = -10x^2 since a = -10 is furthest from zero compared to a = -0.9 and a = 9. Set up a number line to help see this. You can also use absolute values to get the job as well.
Therefore, y = -10x^2 has the most narrowest graph.
Molly=4x+10
Ron=20-5x
Molly + Ron=(4x+10)+(20-5x)=(10+20)+(4x-5x)=30-x.
Answer: they have all togehter 30-x
and for the answer for the second question
4x+10-(20-5x)
4x+10-20+5x
9x-10
