Part a: the first cereal is y=7x and the second one is y=10x so they are $3 apart.
part b: y=7*4 (28) and y=10*4 (40) is $12 apart so she will save $12 each month.
Dividing by 2, we have S/2=lw+lh+wh. After that, we subtract lh from both sides to get S/2-lh=lw+wh. Next, we divide both sides by w to get (S/2)/w=l+h. Next, we divide by S/2 to get 1/w=(l+h)/(S/2). Lastly, we multiply by w and divide by (l+h)/(S/2) to get w=(S/2)/(l+h)
Perpendicular sides or lines meet at right angles. The conclusion that can be reached is that:
<em>1. all of the rings are perpendicular to that side.</em>
The statements in the question can be listed as:
- <em>Rings in the ladder are parallel</em>
- <em>Top ring is perpendicular to the side of the ladder</em>
<em />
From statements 1 and 2 above, we understand that;
<em>All other rings in the ladder are parallel to the side ring</em>
This means that the relationship between the top ring and the side of the ladder is the same as the relationship between other rings and the side of the ladder
i.e. the side rings are also perpendicular to the side of the ladder
Hence, the conclusion that can be reached is:
<em>1. all of the rings are perpendicular to that side.</em>

Answer:
w = - 15
Step-by-step explanation:
Assuming you mean
= - 4 ( multiply both sides by 3 to clear the fraction )
w + 3 = - 12 ( subtract 3 from both sides )
w = - 15
