I need help I need to know the missing side​

At school there are 526 students and 263 are girls about how likely is it that a randomly chosen student will be a boy

Ily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4 how can her partial solution be interpreted?

Two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130
