Mr. Leonard gets £ 45.84375 as discount
<em><u>Solution:</u></em>
The oil tank can take up to 1200 liters of oil
There are already 450 liters of oil in the tank
The remaining oil which is to be added is given by :
Remaining oil = 1200 - 450 = 750 liters
The price of oil is 81.5 p per liter
<em><u>Then calculate the total price of 750 L of oil:</u></em>
Thus total price is 61125 p
Mr Leonard gets a 7.5% discount on the price of the oil
Therefore,
Discount amount = 7.5 % of 61125
Thus he gets 4584.375 p
We convert p to £
1 p = 0.01£
4584.375 x 0.01 = £ 45.84375
Thus he gets £ 45.84375 as discount
The expression in A is equal to:
y = 8 + 3x
It can be observed that the equation is in the slope-intercept form which is equal to,
y = mx + b
where m is slope and b is intercept.
The slope and intercept therefore of this equation of the line are equal to 3 and 8, respectively.
For Part B:
The slope of the line can be calculated through the equation,
m = (y₂ - y₁) / (x₂ - x₁)
Substituting,
m = (5 - 2)/ (0 - -1) = 1.5
The intercept, b, is the value of y when x = 0. From the tabulation, y = 5 when x = 0. Thus, the intercept is equal to 5.
Comparing the slopes and intercepts of the equations, we can say that the slope of the second is only half that of the first and the intercept of the second is 3 less than that of the first equation.
You need to work backwards
if it is no more than 9 units away from 8
thus x must be 8-9<x<8+9 solving -1<x<17
so the answer is 4.

Answer:
Part A: m+1.37=7.9
Part B: 6.53 miles are left to be repaired.
Step-by-step explanation:
Given,
Length of repaired part = 1.37 miles
Total length to be repaired = 7.9 miles
Miles left to be repaired = m
Part A:
Create an equation to show the relationship between the number of miles repaired and the number of miles left to be repaired, m.
Miles left to be repaired + Length of repaired part = Total length to be repaired
m+1.37=7.9
Part B
How many miles are left to be repaired?
Subtracting 1.37 from both sides
6.53 miles are left to be repaired.
