- 6 \frac{1}{4}  - ( - 2 \frac{1}{8} )

=  - 6 \frac{1}{4}  + 2 \frac{1}{8}

=   \frac{ - 25}{4}  +  \frac{17}{8}

=   \frac{  - 50}{8}  +  \frac{17}{8}

= \frac{ - 50 + 17}{8}

=  \frac{ - 33}{8}

=  - 4 \frac{1}{8}

Consider the following equations: −x − y = 1
Vlad1618 [11]
Solve for X and y using both equations the point you get will be the point they cross eachother
-x-y=1
y=x+3
-x-(x+3)=1
-x-x-3=1
-2x-3=1
+3 both sides
-2x=4
÷-2 both sides
x=-2
solve for y
y=-2+3
y=1

1. Chris takes 25 minutes to replace one car tyre.
vekshin1

Chris and Jim must replace a <em>total</em> quantity of 17 tyres.

<h3>What is the minimum number of tyres to be replaced?</h3>

In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:

(25/20) · x - x ≥ 3

(5/20) · x ≥ 3

x ≥ 12

Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.
