I would rather use a ruler but it depends on what you are doing.
Answer:
w = 
Step-by-step explanation:
p = 2l + 2w Subtract 2l from both sides of the equation
p - 2l = 2p Divide both sides by 2
= w
If both numbers were the same, they would be -11 and -11 .
Take '1' away from one of them and give it to the other one.
You haven't changed their sum, but now they're<em> -12</em> and <em>-10 </em>.
Answer:
Let t be the number of toys.
Since, the toy drive already has collected 300 toys
⇒ t+ 300
Also, it is given that the goal of a toy drive is to donate more than 1000 toys.
We get an inequality:
⇒
Solve an inequality:

Subtract 300 from both sides we get

Simplify:
t > 700
Therefore, more than 700 toys does the toy drive need to meet its goal.
An inequality is;
; t > 700
Answer:
$12.075
Step-by-step explanation:
To find how much one pound of walnuts cost you need to divide 3.45(cost) and 2 (how much) and you get 1.725. That means how much one pound cost ...now that you know that all you have to do is multiply 1.725 by 7. You get $12.075 :)
