Suzanne says the two expressions 2(3a – 2) + 4a and 2(5a – 2) are equivalent? Is she correct? Explain why or why not?
pashok25 [27]

Answer:

Suzanne is incorrect.

Step-by-step explanation:

To figure out if the two equations are equivalent, we can simplify each one of them.

Simplifying the first equation, we get:

2(3a-2)\\6a-4\\

Simplifying the second equation, we get:

2(5a-2)\\10a-4

Now that both equations are simplified, we can see that the equations are not equivalent. Suzanne is incorrect.

Jamie sees a sale at the Gaming Store where all games are the same price. He buys 3 video games. His sister talks him into also
galina1969 [7]

Answer: 3x + 5 = 57.50

Step-by-step explanation:

Assume that the price of one video game is x. Jamie bought 3 video games so the expression will be:

= 3x

His sister talked him into buying two $1.50 candy bars and a $2.00 drink. The total of this is:

= 1.50 + 1.50 + 2.00

= $5.00

The total amount spent on both the video game and the snacks is $57.50. Equation will therefore be:

3x + 5 = 57.50

The local grocery store has sorted apples by size. The distribution is approximately normal. The large apples have a mean diamet
NikAS [45]

Answer:

0

Step-by-step explanation:

Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)
