AD = BC
x+2 = 2x - 3
2x -x = 2+3
x = 5
AB = DC
2y +1 = 3x - 2
2y + 1 = 3(5) - 2
2y + 1 = 13
2y = 13 - 1
2y = 12
y = 6
answer: x = 5 and y = 6
It’s c because the x is exterior angles
If we know that she got 75%, we can write it as the fraction 75/100.
We also know that she got 60 correct out of an unknown number of questions, which we can call 'x'
We means we know that 75/100 = 60/x (the number of questions)
Cross multiply to get an equation.
75 * x=60 * 100 -----> 75x=6000
Divide both sides by 75 to solve for x.
6000/75=80
x=80, meaning that her test had 80 questions on it.
