x<-4
Step-by-step explanation:
If the circle is hollow that means it is either < or >. Since the arrow is pointing to the left it is <.
11.
Just look at the graph, and you will see that an original inequality is:
Multiply both sides by 5:Add 6 to both sides:And you will get an equivalent inequality to

Let x be number of pizza sold
Y be the number of sub solds
Equation 1
Y = x + 11
Equation 2 ( earned total $ 233)
5x + 3y = 233
Solving the equations simultaneously
X = 25 pizzas were sold
<span>Y = 36 subs were sold</span>
Let l represent the length and w represent the width of the yard.
The property is twice as long as it is wide. hence:
l = 2w
The total area of her yard is 1,000 m². hence:
lw = 1000
2w(w) = 1000
w² = 500
w = 22.4 m
Hence the approximate width of her backyard is 22.4 m
