3x-6+10x+15=35
10x+3x=35-15+6
13x=26
x=2
Answer:
Step-by-step explanation:
First, we can factor all of the following equations to turn that weird, huge looking thing into 
÷ 
× 
. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into × 
× 
. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into which is our final answer, as it cannot be simplified further.
Hope this helped! :)

Answer:</h3>
He will need at least 122 tiles
<h3>
Step-by-step explanation:</h3>
Get the area of the tiles
5*14= 70 square inches per tile

Answer:
24%
Step-by-step explanation:
there are 50 numbers total
number of 4's: 7
number of 7's: 5
it's asking for the odds of a 4 or a 7 meaning that they're fine with either one. that means you can ADD the number of them up!
7 + 5 = 12
to get the odds, we need to divide!
convert that into a percent!
24%
let me know if you're still confused :))
