2x - 3y = 6
-3y = 6 - 2x
y = -2 + 2/3x
P-4(p-2(3-p))=12 remove the parentheses
P-4(p-6+2p)=12 collect like terms
P-4(3p-6)=12 remove the parentheses
P-12p+24=12 collect like terms
-11p+24=12 move the constant to the right
-11p=12-24 calculate
-11p=-12 divide both sides
P=12/11
Alternative form
P=1 1/11
Answer:
1. You would divide 30 by 3 which would be 10 bags of leaves per hour.
2. You would divide 34 by 17 which would be 2 quizzes per week.
3. You would have 7 people because it says Mrs. Sapanaro and the other 6. So you divide 245 by 7 which is 35$ per person.
Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
She is 31

J-Joshua
F3-J4=31
F=J2+5
(J2+5)(3)-J4=31
J2+5=31
J2+5-5=31-5
J2=26
J2/2=26/2
J=13
F=13(2)+5
F=26+5
F=31
