The answer is 100 m^2
Because you just square the side lengths, 10 times 10 equals 100 as does 4 times 4 equals 16
9. 1 is the y-in and 5 is the slope.
10. I couldn’t see the side of this one but I hope 9 helped :)
Answer:
one cup of coffee costs $2, while one bottle of water costs $1
Step-by-step explanation:
We can represent this using two equations:
- Variable <em>x </em>represents cups of coffee, and variable <em>y</em> represents bottles of water.
5<em>x</em> + 2<em>y</em> = 12
4<em>x</em> + 7<em>y</em> = 15
Your answer for the value of <em>x</em> and <em>y</em> should be
<em>x</em> = 2
<em>y</em> = 1
Therefore, one cup of coffee costs $2, while one bottle of water costs $1.
7 hours is the correct answer
