Answer: (A) If it is a bib, then it is a bab
<u>Step-by-step explanation:</u>
p: The bib is a bub.
Rewrite it as: If it is a bib, then it is a bub.
- hypothesis: It is a bib
- conclusion: It is a bub
q: The bub is a bab.
Rewrite it as: If it is a bub, then it is a bab
- hypothesis: It is a bub
- conclusion: It is a bab
The conclusion of p equals the hypothesis of q so the Law of Syllogism can be applied --> hypothesis of p → conclusion of q
Since no value is given to Eva, we'll call her x. Justin, then, is 7.50+x. That leaves Emma, who would be Justin (7.50+x) -12. If we add them all together we get 63. So our equation is
x + (7.50+x) + (7.50+x)-12 = 63
Combine like terms
x+x+x + 7.50+7.50-12 = 63
3x + 3 = 63
3x = 60
x = 20
Since we said Eva is x then Eva has 20 dollars.
Justin is 7.50 + x so 7.50+20=
$27.50
Emma is Justin - 12 so 27.50-12= $15.50
Let's check our answer...
15.50+27.50+20 = 63
63=63
It checks!
Different regular shapes have certain formulas that you use to find their volume. For example
volume of a cube is Base x Width x height
Volume of cylinder is pie r^2 x h
etc...
This is the correct answer
