Step-by-step explanation:
every 2 hours will be a positive line segment relating to the 7 meters give you the point of 14 every 4 hours
Answer: See explanation
Step-by-step explanation:
7x - 2(x + 3y) + 3y
= 7x - 2x - 6y + 3y
= 5x - 3y
Will got 5x + 9y because he didn't multiply the values in the bracket by the minus sign outside the bracket. He multiplied the values by +2 rather than -2. This resulted in the wrong answer that he got.
When a sign has the underline, it means it is also equal to.
for example,
x

10
so the solution for "x" is greater than or equal to 10
hope this helps!
