Step-by-step explanation:

Vẽ đồ thị y = 2x (1):

Cho x= 0 ⇒ y= 0 ta được O (0, 0)

Cho x= 2 ⇒ y = 4 ta được điểm (2; 4)

- Vẽ đồ thị y = 0,5x (2):

Cho x= 0 ⇒ y = 0 ta được O (0; 0)

Cho x = 4 ⇒ y = 2 ta được điểm (4; 2)

- Vẽ đồ thị y = -x + 6 (3):

Cho x = 0 ⇒ y = 6 được điểm (0; 6)

Cho y = 0 ⇒ x = 6 được điểm (6; 0)

2/3 because 16 are chocolate and 8 are strawberry so you get 24 cupcakes in total which would give you your denominator and 16 would be your numerator because your trying to find the fraction of chocolate cupcakes so you have 16/24 you would simplify 8x2 is 16 and 8x3 is 24 then you have 2/3 as your answer. hope this helps

A turtle walks 7/8 mile in 50 minutes.

Convert 1 hour to minutes and you get 60 minutes.

50/60 = 5/6. The turtle walks 7/8 mile in 5/6 hour

$\frac{\frac{7}{8} }{\frac{5}{6} } = 21/20$
