Eco algebra 1.
which of the following equations is an example of the commutative property?
a. (3)(6+10) = 18 + 30
b. 18 + 30 = 30 + 18
c. (3)(6) + (3)(10) = 3(16)
d. 48 = 48
let the equation of a line be described by equation a:
10y - 5x = 40
what are the y-intercept and slope of the line?
a. the y-intercept is 40, and the slope is 10
b. the y-intercept is 10, and the slope is 40
c. the y-intercept is 40, and the slope is 2
d. the y-intercept is 4, and the slope is 0.5

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
