What is the value of y in this system of equations: 3x + y = 9 y = –4x + 10 ?

Ahat [919]

<span>3x + y = 9 (I)
</span><span>y = –4x + 10 (II)
------------------------
</span> $\left \{ {{3x + y = 9 } \atop {y = -4x + 10 }} \right.$

Pass the incognito "4x" to the first term, changing the signal when changing sides.
<span>-------------------------
simplify by (-1)
</span> $\left \{ {{3x + y = 9.(-1)} \atop {4x + y = 10 }} \right.$ <span>

-------------------------
</span> $\left \{ {{- 3x - \diagup\!\!\!\!y =-9} \atop {4x + \diagup\!\!\!\!y = 10}} \right. 
$
<span>
-------------------------
</span> $\left \{ {{- 3x = - 9} \atop {4x = 10}} \right.$ <span>

-----------
</span> $\boxed{x = 1}$ <span><span>

</span></span><span>Substitute in equation (I) to find the value of "Y".

</span>3x + y = 9 (I)
3*(1) + y = 9
3 + y = 9
y = 9 - 3
$\boxed{y = 6}$

Answer:
$\boxed{\boxed{ \left \ {{x=1} \atop {y=6}} \right. }}$

A sumo wrestling ring is circular and has a circumference of 4 . 6 π meters 4.6π meters. What is the area A A of the sumo wrestl

LUCKY_DIMON [66]

Answer:

$A=5.29\pi$

Step-by-step explanation:

<u>Formula for circumference of a circle is</u>:

Circumference = $2\pi r$

<em>Given circumference of the ring is $4.6\pi$ </em>

<em>Now solving for the radius gives us:</em>

$2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3$

We know that area of a circle is $\pi r^2$ , substituting the value of r we found, we get the area as:

area (A) = $\pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi$

Hence the Area (A), in terms of $\pi$ is $5.29\pi$
