The written portion of bens driving test had 40 questions Ben correctly answered 12 more questions than he missed how many quest

lilavasa [31]

We wil name x to the amount of correctly answered questions. Then, we get:

$(x-12)+x=40$ $2x-12=40$ $2x=40+12$ $2x=52$ $x=\frac{52}{2}$ $x=26$

Ben had 26 correct answers, so he missed 40-26= 14.

Find the value of x in each case. Give reasons to justify your solutions! answer ASAP

schepotkina [342]

Answer:

x = 19

Step-by-step explanation:

YZ || XW, so ∠Y = ∠W

if ∠Y = ∠W, then ∠W = 2x

since the sum of the angles of a triangle is 180 degrees:

(3x-5) + 2x + 90 = 180

x = 19
