Answer:
Substituting x= 2y-2 in 5x
5(2y-2)
10y-10
10(y-1)
First is to make equations for both sides.
Let x be the number of the miles.
a be the charge of the first company
b be the charge of the second
a=$35+$0.25(x), b=$40+$0.20(x) .
then a=b
Substitute the equations
$35+$0.25(x)=$40+$0.20(x)
$0.25x - $0.20x = $40 - $35
$0.05x = $5
x= $5/$0.05 , cancel out the unit.
x= 100
To justify substitute x to both the equations a and b.
a= 35 + 0.25(x)
a= 35 + 0.25(100)
a= 35 + 25
a= $60
b= 40 + 0.20(x)
b= 40 + 0.20(100)
b= 40 + 20
b= 60
a=b
60=60.
Answer:23
Step-by-step explanation:
Answer:
80 * 80% = 64 So it's not A
80 * 55% = 44 so it's not B
80 * 100% = 80 so it's not C
80 * 125% = 100 so D is your answer
Step-by-step explanation:
In this question, you have to use the Pythagorean theorem. (the formula is in the box, ‘a squared’ and ‘b squared’ is used to find the legs of the triangle, while the ‘c squared’ in the formula is used to find the hypotenuse of the triangle.
