<span>A = hours for plan A
B = hours for plan B</span>
<span>Monday: 6A + 5B = 7
Tuesday: 2A + 3B = 3</span>
use elimination by multiplying the 2nd equation by 3.
Doing that we get 3(2A + 3B = 3) = 6A + 9B
= 9
<span>So the two equations are now:
6A + 9B = 9</span>
6A + 5B = 7
Subtract and we have 4B = 2
B = 2/4 = 1/2 of an hour
Now put 1/2 back into either equation to solve for A
<span>6A + 5(1/2) = 7
6A + 5/2 = 7
6A = 14/2 -5/2
6A = 9/2
divide by 6 to get A = 9/12 = ¾ hours</span>
<span>Plan A = 3/4 hour</span>
<span> Plan B = 1/2 hour</span>
Equations are separated by an equal sign. The value of x is given as -6/5
<h3>Equations and values</h3>
Given the equations below;
5(3x + 4) = 2
Expand
5(3x) + 5(4) = 2
15x +20 = 2
Subtract 2 from both sides
15x = 2 - 20
15x = -18
x = -18/15
x = -6/5
Hence the value of x is given as -6/5

Step-by-step explanation:
middle
The required ratio is give by $40/m, 4 miles/min, 30 mile/liter. .
Let, just assume a vehicle is given an economy of $280 of 7m.
<h3>
What is the Ratio?</h3>
The ratio can be defined as the comparison of the fraction of one quantity towards others. E.g.- water in milk.
Now,
The ratio can be given as for economy = 280/7
= $40/m
here for new values,
suppose the vehicle travel for 40miles in 10 mins
ratio = 40/10= 4 miles/min
and vehicle consumes 2 liter fuel on 60 miles of distance ratio can be given as
ratio = 60/2 = 30 mile/liter.
Thus the required ratios can be given as $40/m, 4 miles/min, 30 mile/liter.
