Answer:
20 band posters
Step-by-step explanation:
Set up a proportion where x is the number of band posters she should sell:
= ![\frac{24}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7Bx%7D)
Cross multiply and solve for x:
2400 = 120x
20 = x
So, she should sell 20 band posters.
If she sells 20 band posters and 24 movie posters, the ratio will be 96:80, which is the same as 120:100. Simplified, both ratios are 1.2:1
-2y^2 + 6y + 2 = 0
a = -2, b = 6, c = 2
x = (- b + - sqrt(b^2-4ac))/(2a)
x=(-6+-sqrt(36-4*-2*2))/-4
x=(-6+-sqrt(36+16))/-4
x=(-6+-sqrt(52))/-4
x = (-6 +- 2sqrt13)/-4
x = (3 + - sqrt13)/2
The answer would be 12 inches. I have the most faith in my answer.
Answer:
acorns
Step-by-step explanation:
20x=9y
9/20 to 5/9
5/9 of the acorns collected are from Hannah
9/20 of the conkers collected are from Hannah
5/9 is larger than 9/20
Hannah collected more acorns
The line of reflection that would map ABCD onto itself is the line of the diagonal which is -3x + 3y = 9
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The line of reflection that would map ABCD onto itself is the line of the diagonal. The diagonal passes through A(-3, 0) and C(-1, 2), hence:
y - 0 = [(2 - 0)/(-1-(-3))](x - (-3))
y = x + 3
-x + y = 3
-3x + 3y = 9
The line of reflection that would map ABCD onto itself is the line of the diagonal which is -3x + 3y = 9
