Linda conducted a school survey and asked 8th-grade students about their favorite NFL team. The results are in the table below. Based on the results of the survey, what was the probability of an 8th-grade student choosing the Pittsburgh Steelers as their favorite NFL team?
A 5/4

B 3/10

C 19/25
D6/25

6/25

Step-by-step explanation:

Add up the total number of votes for each NFL team (125); numerator.

Number of votes for Pittsburgh Steelers (30); denominator.

You get 30/125, then you round ⇒ (Divide numerator and denominator by 5) = 6/25.

(x+3)(x+7)

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
