Answer:
The question that you asked is kind of confusing but I think that I have it.
Step-by-step explanation:
So, as you said Marvin moves by a 1 by 1. 1 to the right and then 1 up. But there is an obstacle at (4,3). To evade that obstacle I would suggest going up four, and then over 1. To be honest, there are a ton of ways. All you have to do is just steer clear of (4,3).
If the number is x
the expression is -
x/2 - 7= 1 + 5/10
Answer:
19a.
<u>2(s+7)≤30</u>
say s stands for the money they need for snacks.
there are 2 friends who both pay $7 and whatever s is, so we put s+7 in parenthesis to evenly distribute it between them. it has to be less than or equal to $30 because that's the only money they have
19b.
2(s+7)= 2s+14
30-14=16, so the friends have 16 between them
16 divided by 2 is 8, so the equation would be
<u>s≤8</u>
