Answer:
11/25
Step-by-step explanation:
44% can be written as a Fraction as 44/100. This fraction can ultimately be simplified to 22/50 before being finally reduced again to 11/25.
Answer:
He sold 12 phones and 20 accessories
Step-by-step explanation:
X × 10 = 120. Y × 2 = 40
12 × 10 = 120. 20 × 2 = 40
120 + 40 = $160
Step-by-step explanation:
The final equation of line passing through (6,9) and (11,2)
![y=-\frac{7}{5}x+\frac{87}{5}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B5%7Dx%2B%5Cfrac%7B87%7D%7B5%7D)
Further explanation:
The general form of equation is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
We have to find the slope first
![m=\frac{y_2-y_1}{x_2-x_1}\\Here\\(x_1,y_1)=(6,9)\\(x_2,y_2)=(11,2)\\Putting\ the\ values\\m=\frac{2-9}{11-6}\\=-\frac{7}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5CHere%5C%5C%28x_1%2Cy_1%29%3D%286%2C9%29%5C%5C%28x_2%2Cy_2%29%3D%2811%2C2%29%5C%5CPutting%5C%20the%5C%20values%5C%5Cm%3D%5Cfrac%7B2-9%7D%7B11-6%7D%5C%5C%3D-%5Cfrac%7B7%7D%7B5%7D)
Putting the value of m in general form
![y=-\frac{7}{5}x+b](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B5%7Dx%2Bb)
For finding the value of b, putting (6,9) in equation
![9=-\frac{7}{5}(6)+b\\9=-\frac{42}{5}+b\\9+\frac{42}{5}=b\\b=\frac{45+42}{5}\\](https://tex.z-dn.net/?f=9%3D-%5Cfrac%7B7%7D%7B5%7D%286%29%2Bb%5C%5C9%3D-%5Cfrac%7B42%7D%7B5%7D%2Bb%5C%5C9%2B%5Cfrac%7B42%7D%7B5%7D%3Db%5C%5Cb%3D%5Cfrac%7B45%2B42%7D%7B5%7D%5C%5C)
![b=\frac{87}{5}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B87%7D%7B5%7D)
Putting the values of b and m
The final equation of line passing through (6,9) and (11,2)
![y=-\frac{7}{5}x+\frac{87}{5}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B5%7Dx%2B%5Cfrac%7B87%7D%7B5%7D)

The answer is 6.5 and what I did is I took the mixed fraction (2 2/4) and I turned It into a decimal. After I knew it was 2.5 all I had to do was use the formula A=lw to get my answer on what the width was.
Step 1: Replace the variables with numbers
A=lw
A=2(1.25)
A= 2.5 (Fraction 2 2/4)
Step 2: Use the perimeter formula (P=l+w+l+w or P=(l+w)2)
P=(l+w)2
P=(2+1.25)2
P=(3.25)2
P=6.5
Answer is 6.5 I hope this helped ^^
