18)Fort Lauderdale is playing on a newly designed football field that is numbered from the 0 to the100-yard line. Making it from one end zone to the other end zone scores
points. They are on the 50-yard line. The quarterback throws for a 20-yard gain. On
the next play, there is a fumble, which results in a 15-yard loss. To make matters
worst, they are called for 10-yard loss for being offsides. What yard line is Fort
Lauderdale on now? (Write an expression then simplify

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
