What do you mean by that?
It is given in the question that
Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.
Maximum she can spend is $200. That is

And

And that's the required inequalities .
It says it’s 5 points not 10 points!
Reduce the expression, if possible, by cancelling the common factors.
Exact Form:
−4/15
Decimal Form:
−0.26
Basically do
y2-y1 divided by x2-x1
14-10 divided by -7-8
which equals -4/15
Answer:
17.5
Step-by-step explanation:
Given that the variables x and y have a proportional relationship.
i.e. y is directly proportional to x or can be written as
y = mx where m is the constant of proportionality.
When x =2, y =7
Substitute this to get the value of m.
7 =2m or m = 3.5
Thus the relationship between x and y is
y = 3.5x
So when x=5, y = 3.5(5) = 17.5
