Answer:
add all the sides together
a+b+c+d
Greg and George bought shoes at a local store. Greg bought one dress shoe and 4 sneakers and spent less than $400.
George bought one dress shoe and 6 sneakers and spent more than $400.
Inequality signs < and > denote less than and greater than respectively.
To solve the above inequalities in order to find x and y prices, a pair of solutions will be the result since linear inequalities with two variables will have a range of solutions
In other words, to find x and y for the inequalities we find a point (x,y) that satisfies the inequality.
Example: if the price of a dress shoe is $80 and the price of a sneaker is $60, it satisfies the system of inequalities for Greg and George since their shoe expenses stay below and above $400 respectively.
We could then say that the point (80,60) is one of the solutions to the inequalities.
We could graph the inequalities in order to find points on the graph that satisfy the inequalities. To graph the inequality we make the equation a linear equation x+4y=400 and plot a straight line in accordance to the inequality. All points above the line satisfy George's inequality and vice versa.

Answer:
hey i am also on this problem did you ever figure it out
Answer:
There are 56 stuffed animals and 28 mystery boxes in the claw arcade machine
Firstly, we assign variables.
Let the number of stuffed animals be x and the number of mystery boxes be y
The probability of selecting a stuffed animal is x/84 while the probability is selecting a mystery box is y/84
Now, since the total probability can be 1:
This means that
x/84 + y/84 = 1 •••••••(i)
Now from the question, we were told that the probability of selecting or winning a stuffed animal is twice that of winning a mystery box
Thus x/84 = 2 * y/84
X/84 = y/42
Let’s substitute this into equation 1
y/42 + y/84 = 1
(2y+ y)/84 = 1
3y/84 = 1
3y = 84
y = 84/3
y = 28
Since x + y = 84
x = 84 - y
x = 84-28 = 56
Hope this helps!!
