X - y = 3<br> x + 3y = 9
Ugo [173]
Solve for one of the variables in the first equation (in this case, I will solve for X):
X = Y + 3

Then use that value of X in the second equation to solve for Y:
X + 3Y = 9
(Y + 3) + 3Y = 9
4Y + 3 = 9
4Y = 6
Y = 1.5

Use the value of Y we just found in the X equation we created:
X = Y + 3
X = 1.5 + 3
X = 4.5

Therefore X = 4.5 or 9/2 and Y = 1.5 or 3/2.

Help I will be marking brainliest!!!!
artcher [175]

Answer: <em>A. 241 feet</em>

Step-by-step explanation:

<em>The figure shows two rectangular triangles. </em>

<em>These triangles are similar since they have two identical angles: </em>

<em>the first angle is 90 degrees; </em>

<em>the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection. </em>

<em>The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.</em>

<em>Let's make the proportion:</em>

<em />\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\<em />

<em>It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:</em>

<em>341.25 - 100 = 241.25 (feet)</em>

<em>241.25 ≈ 241 (feet)</em>
