Answer:
x = 4
y = 6
Step-by-step explanation:
3x + 4y = 36
3x + 4(-1/2x + 8) = 36
3x - 2x + 32 = 36
x + 32 = 36
x + 32 - 32 = 36 - 32
x = 4
y = -1/2x + 8
y = -1/2(4) + 8
y = -2 + 8
y = 6

Answer:
940
Step-by-step explanation:
<em>To find the original price of something that been discount do the following:</em>
- <em>Subtract the discount from 100 to get the percentage of the original price.</em>
- <em>Multiply the final price by 100.</em>
- <em>Divide by the percentage in Step One.</em>
<em>Or we can do the following:</em>
<em>We shall consider the original price as x; hence the discount can be considered as (x−263.20). We can write the equation:</em>
<em>x · 72/100=x - 263.20</em>
<em>x · 18/25 = x - 263.20</em>
<em>Multiply both sides by 25</em>
<em>18x = 25(x - 263.20)</em>
<em>Open the brackets.</em>
<em>18x = 25x-6580</em>
<em>Add 6580 to each side.</em>
<em>6580 +18x = 25x</em>
<em>Subtract 18x from each side.</em>
<em>6580 = 7x</em>
<em>Subtract 7x from each side.</em>
<em>x = 940</em>
<em>Check Answer:</em>
<em>940 * 72% = 676.80</em>
<em>940 - 676.80=263.20</em>
<em>Hence, the regular price is 940.</em>

Answer:
Step-by-step explanation:
In the given image, you can observe we have two right triangles.
Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.
If the triangles are similar, we can define the following proportion between sides.
Now we use the Pythagorean's Theorem to find each hypothenuse.
Therefore, the missing sides are
