Answer:
Step-by-step explanation:
-2(p + 4) = 3 - 3p + 1p.....combine like terms
-2(p + 4) = 3 - 2p...distribute the -2 through the parenthesis
-2p - 8 = 3 - 2p
-2p + 2p = 3 + 8
0 = 11 <==== no solution
if it is a false statement, it has no solutions
if it ends like : 6 = 6 or -2 = -2, then there is infinite solutions
if it ends like : x = 8 or x = -5, then there is 1 solution
Answer:
3 cm
Step-by-step explanation:
Area=length x width
6=length x 2
Length x 2=6
Length=6/2
Length=3
Answer:
D.
Step-by-step explanation:
The problem is clearly addition, so we can rule out B and C. Associative property is the movement of the parentheses, whereas commutative property is the movement or reorganization of the numbers. The parentheses moved in this problem, so it is associative. I suggest reviewing these properites, they come in handy later and are good to know :)
Answer:
130 calories in the ice cream and 500 calories in the pie.
Step-by-step explanation:
Let the amount of calories in the scoop of ice cream be x. the amount of calories in the piece of pie be 3x-20. we know that x+3x-20=500.
4x-20=500
If we add twenty to both sides, we end up with:
4x=520
Divide both sides by four, and you get x=130.
there are 130 calories in the scoop of ice cream and 130*4-20=500 calories in the pie.
