Answer:
Z=BY+R
Step-by-step explanation:
B=z-r/y
separate Z by it's self. Z= B * Y
Z =BY+R
Simple easy stuff should have no problems. I would love some more math like this bring it. C:
Answer:
x=13
Step-by-step explanation:
Set it up like a regular equation. I used:

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
Ex. 85+91= 176
176 divided by 2 = 88
Therefore the minimum score he can get is a 91
Root: A/2 is the equation
your answer is 1.38
