The statements expresses as
w <span>∝ b
where w = body's weight, b = amount of blood
Changing it into a direct variation becomes
w = kb or k = w/b
where k = proportionality constant
We know that k is obviously constant, we equation it into two states as
w</span>₁/b₁ = w₂/b₂
Given that w₁ = 160 lb, b₁ = 4.6 qt, b₂ = 175, w₂ = 175 lb. Then b₂ will be
160/4.6 = 175/b₂
b₂ = 160/(4.6*175) = 160/805 = 0.20 quarts

2² simplified means 2 times 2 (2 times itself) so
2² = 4
2×2=4
2²=4
Now , it doesn't make any difference with a number like 2 .
Suppose we had 3 :
3² = 9
3² is not the same as 3 ×2 , and here's the reason for that :
3²=3×3=9
3 × 2 = 6
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.

You know that there are 64 children under 12 and 103 total people. This means that the number of people over the age of 12 has to be (103 - 64). To find the amount of money earned from this group of people, just multiply by the price for people over the age of 12: $45. Thus, one part of your equation has to be (103 - 64)∙45.
<span>The second part of the equation is a bit more difficult. You know that x = the number of children under 3, and those children are free. All we need to find is the number of children between 3 and 12 who have to pay and then multiply by their price: $34. So, just subtract the free children from the total children and multiply by 34: (64 - x)∙34. </span>
<span>Put this all together and you get (64 - x)∙34 + (103 - 64)∙45</span>
