Answer:
x = 6
Step-by-step explanation:
<em>This can be written as a ratio</em>
7 : 2
21 : x
<em>If you times one side by 3, you have to multiply the other side by three too:</em>
2 × 3 = 6
∴ x = 6 when y = 21
Answer:
It does not.
Step-by-step explanation:

is our set of solutions. Answering your question, it does not.
Answer:
Speed = Distance/Time. so if you rearrange this it means that you get Time = Distance/Speed. Therefore 240/60 = 4 then you just think of doing miles(distance)/Miles per hour(speed) which leaves you with 4 hours which=C
Step-by-step explanation:
Sometimes to make it easier i use a triangle from this equation, you cover up what one you want and then you do what it says. If you cover up distance then you are left with speed x time. Likewise if you cover up speed. Speed = Distance / Time.
