First set up a proportion
240/160 = 320/200
Cross multiply and if the left equals the right it is similar.
Answer:
x = 20
Step-by-step explanation:
(3x + 50) = (6x - 10)
Subtract 6x on each side
3x + 50 - 6x = -10
Combine the x values together
-3x + 50 = -10
Subtract 50 on each side
-3x = -60
Divide each side by -3
x = 20
28 062 ÷ 3
9 354
9 354 x 3
28062
D because it would 44 below since 4 times 7 = 28 so it would switch over for to 6 times 7 =44
It would be the first one.
