You can formulate your own equations by analyzing the given problem and its statements. You can do some illustrations so you can understand it better. Introduce some variables and the rest is algebra. For example:
An orange costs $2 while a banana costs $1.5. How many oranges and bananas do you have to buy such that the total cost would equal to $20. You bought a total of 12 fruits.
First, you have to introduce variables. Let 'x' be the number of oranges and 'y' be the number of bananas. One equation you can get from here is knowing the amount of total cost: 2x + 1.5y = 20. Then, the other equation would be knowing the amount of fruits: x+y=12. You have two unknowns and two equations. Hence, you can solve the problem. Solving them simultaneously, you would get that x=4 and y=8.
Answer
y= 4
Step-by-step explanation:
6x-7y=22
6x(-1)-7y=22
-6-7y=22
-7y=22+6
-7y=28
y=-4
Answer: I'm pretty sure that it´s C but Im not sure.
Sorry if that's wrong.
Answer:
<em>The answer is</em> <u><em>48m</em></u><em>, I hope this answer is correct!</em>
Step-by-step explanation:
For each cube there are 6 sides so, 1 cube has the value of 6m so, since there are 8 cubes, the volume is 48m.

What you can do is start with the key details in it... the main ones are that the bacteria grows every 30 minutes, you start with 1 bacteria, and the end time is 180 minutes. Basically you know that 3 goes into 18 6 times so 30 goes into 180 6 times which means that if you started with 1 bacteria you will end up with 7. Understand?
