A truck uses 1 gallon of diesel for every 12 miles traveled. The amount of diesel left in the gas tank, r gallons, after traveli
Snezhnost [94]

<em>The question has missing details. However, general questions that could be asked is as follows:</em>

<em>(1) The number of miles traveled after using (say) 5 gallons</em>

<em>(2) The number of gallons used after traveling for (say) 36 miles</em>

Answer:

See Explanation

Step-by-step explanation:

Given

s = 120 - 12r

A linear equation is represented as:

y = c + mx

Where

c =y\ intercept and

m = slope.

c, in this question represents the initial capacity of the tank.

So, the initial capacity is 120 liters

Solving (a): r = 5

s = 120 - 12r

s = 120 - 12 * 5

s = 120 - 60

s = 60

<em>60 miles traveled</em>

Solving (b): s = 36

s = 120 - 12r

36 = 120 - 2r

Collect like terms

2r =120 -36

2r =84

Solve for r

r = 42

<em>42 gallons used</em>

Find 4ab when (a+b)=15 and (a-b)=12
Volgvan
A + b = 15 ..... eq 1
a – b = 12 ...... eq 2

So a = 15 – b
Substitute in eq 2 :

15 – b – b = 12
15 – 2b = 12
–2b = 12 – 15
b = 1.5

So a = 15 – 3/2 = 13.5

4ab = 4 x 13.5 x 1.5 = 81
