<span>let the width of the strip x in meters
we need to find the value of x
Dimensions of the new lawn are given as
</span>(7+x) by (5+x)
Area of the lawn is given as
6.25m^2
<span>
(7+x)(5+x) = 6.25
</span><span>35 + 12x + x^2 = 6.25
x^2 + 12x+28.75 = 0
In the above equation the values are given as
a = 1, b=12, c=28.75
</span>put these values in quadratic equation and you will get the answer.<span />
Answer:
$180
Step-by-step explanation:
To solve, we can set up a proportion and solve.
You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work
45/7.5=x/30
Cross multiply
45*30=7.5*x
1350=7.5x
To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5
1350/7.5=7.5x/7.5
180=x
So, for 30 hours of work, you would earn $180
