First you need to solve for x by subtracting 9 from both sides (-3x less than/equal to 6), then dividing the inequality by -3, which would also flip the sign, so to speak. now you would have x is greater than/ equal to -2. now you would draw a circle above -2, fill it in since it is equal to, and draw the arrow going toward 0 (I think)

The perimeter of a football field in a certain school is 296m. If the breadth is 2/3 of the length, find the sides of the field

MaRussiya [10]

Answer: 88.8 m , 59.2 m

Step-by-step explanation:

Given

Breadth is $\frac{2}{3}$ of length

Suppose length is x m

So, breadth is $\dfrac{2}{3}x$

Perimeter is given by $P=2(L+W)$

Putting values

$\Rightarrow 296=2(x+\dfrac{2}{3}x)\\\\\Rightarrow 296=2(\dfrac{5}{3}x)\\\\\Rightarrow x=\dfrac{296\times 3}{10}=88.8\ m$

Length L is $88.8\ m$

width W is $\frac{2}{3}x=59.2\ m$

Solve the following system: 5x + 4y = 6 -2x – 3y = -1

yanalaym [24]

Answer:

$\left \{ {{y=-1} \atop {x=2}} \right.$

Step-by-step explanation:

$\left \{ {{5x+4y=6} \atop {-2x-3y=-1}} \right. \left \{ {{10x+8y=12} \atop {-10x-15y=-5}} \right. \left \{ {{-7y=7} \atop {-10x-15y=-5}} \right. \left \{ {{y=-1} \atop {-10x-15y=-5}} \right. \left \{ {{y=-1} \atop {-10x+15=-5}} \right. \left \{ {{y=-1} \atop {-10x=-20}} \right. => \left \{ {{y=-1} \atop {x=2}} \right.$
