21 = 7 x 3 or 7(3) if you're no longer using x as a multiplication symbol
-2 4/6 ÷ -2/3=
-16/6 * -3/2=48/12= 4
3y is the supplement of 141 so that means 3y+140=180 so y is 13.33. Since they give you 68, 68+13.33+x=180. So 81.33+x=180 and x=98.66.
Answer:
(0,9) and (18,0)
Step-by-step explanation:
To find the x-intercept, set y = 0. Note how this equation x + 2y = 18 becomes x = 18. Thus, the x-intercept is (18,0).
To find the y-intercept, set x = 0. Then 2y = 18, and y = 9. The y-intercept is (0,9).
