The library is having a contest to guess the number of candy pieces of candy in a jar. johns guess of three times the number of candy pieces in the jar increased by 100 is lower than keisha’s guess of 250 less than twice the number of candy pieces. anna writes the inequality 3x100 < 250-2x, which is incorrect. can you find anna’s mistake? what is the correct way to write this inequality?

The correct way to write the inequality is:

3x+100 ∠ 2x -250

Step-by-step explanation:

Hi, Anna's mistakes:

Three times the number of candy pieces in the jar increased by 100

Number of candy pieces is the variable (x)

Three times the number of candy pieces means "x" multiplied by 3, and increased by 100 means that we have to add 100 to the previous expression (3x +100), not multiply it by 100.

In the other side: "Keisha’s guess of 250 less than twice the number of candy pieces"

Twice the number of candy pieces means that we have to multiply the candy pieces by two (2x), and 250 less means that we have to subtract 250 to the twice of candy pieces (2x) and not the opposite way ( subtract 2x to 250)

2x-250, not 250-2x.

So, the correct way to write the inequality is:

3x+100 ∠ 2x -250

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
