Answer:
27
Step-by-step explanation:
First you need to find x.
It is shown that DE=EF, so we can use this.
5x-3=3x+7
5x=3x+10
2x=10
x=5
Then, you plug in the value of the variable and solve.
6(5)-3
30-3
27 = DF
If I remember right the answer is c
Answer:
It is 79,900, Since 10^4 is 10000.

Answer: 
Step-by-step explanation:
Given
The rug is 4 feet longer than its width
Suppose the length of the width is x
Length is given by x+4
So, the product of length and width is equal to the area of the rug
![\Rightarrow x\left(x+4\right)=A\quad\quad [\text{A=Area of rug}]](https://tex.z-dn.net/?f=%5CRightarrow%20x%5Cleft%28x%2B4%5Cright%29%3DA%5Cquad%5Cquad%20%5B%5Ctext%7BA%3DArea%20of%20rug%7D%5D)
Answer:
y - 3 = -1/2(x-1)
Step-by-step explanation:
Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the required point
Get the slope
m = 1-3/5-1
m = -2/4
m = -1/2
Using the point (1,3), substitute
y - 3 = -1/2(x-1)
2(y-3) = -(x-1)
Hence the required equation is y - 3 = -1/2(x-1)
