Juan is saving money for a new car. he has already saved $200 and plans to save $25 per week. this situation can be represented by the function f(x) = 200 + 25x, where x is the number of weeks. how much money has juan saved after 8 weeks?
$200
$400
$600
$800

400 is the correct answer. I am too lazy to put an explanation, but trust me it's not 800, I just got it wrong.

correct answer is b. 27/8

step-by-step explanation:

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.
