Answer:

m = 2.25

Step-by-step explanation:

In a standard equation of y = mx + b, m is the slope. In this situation, the slope is the price paid per mile.

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the points (3, 8.25) & (11, 26.25)

Plug in these values:

(26.25 - 8.25) / (11 - 3)

Simplify the parentheses.

= (18) / (8)

Simplify the fraction.

18/8

= 9/4

This is your slope.

In a dollar value, it is 9/4 of a dollar, or $2.25 per mile.

Answer:

13 l of 15%, 13 l of 25%, 26 l of 70%

Step-by-step explanation:

solutions:

15%, 25% and 70%

final solution:

52 l of 45%

This includes 0.45*52l= 23.4 l acid

Let's assume:

amount of 15% solution= x
amount of 25% solution= y
amount of 70% solution= z
and we have z=2y

so there are 2 equation:

x+y+z=52

0.15x+0.25y+0.7z=23.4

x+y+2y= 52 ⇒ x+3y= 52 ⇒ x= 52- 3y

0.15x+0.25y+1.4y=23.4

0.15x+1.65y=23.4
0.15*(52-3y)+1.65y=23.4
7.8-0.45y+1.65y=23.4
1.2y=23.4-7.8
1.2y= 15.6

y=15.6/1.2
y= 13 l

--------

x= 52- 3*13= 13 l
z= 2y= 2*13= 26 l
