First, you calculate 10% of 2500, which is 250. Then, you multiple it by five because she borrowed it for FIVE years. The answer is C. :)
Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
It's just saying that you need to find the volume and surface area and then write them in the designated area, which will be on the side or the bottom.
After doing this for all of them, you have to find two matching numbers and put them together on the same side.
For example:
When you got 722, you can just find another square that might say 722 on square area or volume, then just put the numbers together on the same side.
I don't know if this helped but I hope it did!
