Divide total bought by 3 and multiply by 20cents:
210/3 = 70
70 x 0.20 = $14.00
Subtract the amount they paid by the amount they made:
14.00 - 6.50 = $7.50
The profit made was: $7.50
Let m = miles
let c = cost
Create a system of equations.
taxi company 1: c = $1.20m + $2
taxi company 2 c = $1.40m + $1
Set both equations equal to each other to solve for variable m.
$1.20m + $2 = $1.40m + $1
Subtract $1.20 from both sides and Subtract $1 from both sides.
$1 = $0.20m.
Divide each side by $0.20.
5 = m.
Plug 5 into one of our original equations for m.
c = $1.20(5) + $2.
Simplify the right side of the equation
c = $8
In conclusion, c = $8 and m = 5
First, connect the numbers with the same variables. -2y + 8y = 6y. Now 6xy + 7xy + 5xy = 18xy. Final answer is 6y + 18xy.
Assuming that the base is 5 cm and the height is 12 cm, so
by dilating the legs by a scale factor of 2/3, the new dimensions are:
base = 5 cm * (2 / 3) = 10/3 cm
height = 12 cm * (2 / 3) = 8 cm
So the area of a right triangle is calculated using the
formula:
A = b h / 2
A = (10/3) * 8 / 2
<span>A = 13.33 cm^2</span>
