Let x and y equal our two numbers, then add them and set them equal to 27
x+y=27
Pick a variable to represent your larger number, then make an equation for it
y=2x+6
Substitute your equation for that variable back into the original equation so you get everything in terms of one variable.
x+2x+6=27
Solve!
3x+6=27
3x=21
x=7
Plug x back into the equation:
7+y=21
y=14
Answer:
The answer is below
Step-by-step explanation:
The distance between two points is given by the formula:
1) (-4,6) and (3, -7)
2) (-6, -5) and (2,0)
3) (0, -8) and (3, 2)
4) (-1, 4) and (1, -1)
The midpoint (x, y) between two endpoints is given by:
The midpoints of the following segments are:
1) (15, 8) and (-1, -4)
2) M(-5,9) and N[-2.7)
3) P(-3,-7) and Q13.-5)
4) F(12.-6) and G(-8,5)

Answer:
perimeters of the rectangle=p=46.014 metres
Step-by-step explanation:
Given that:
Length (l) = 21 m
Area of rectangle(A) = 42.15 meter-square
Width (w)=?
Required data:
Perimater of Rectangle=p=?
Calculation:
As we know that Area of rectangle=A=l*w
Putting the value we get
42.15 m(square)=(21 m)*w
or w=42.15/21
or w=2.007 m
Now to find perimters of rectangle we know that
p=2(l + w) metres
putting the values
p=2(21+2.007) metres
p=2(23.007) metres
p=46.014 metres
Well if you want to know profit first you get what he makes on hotdogs so 2 times h(2xh) and then to fin profit you subtract 250
so the equation would be 2h-250=p
or you can do 2xh-250=p its the same thing just written differently
