it must be 0,125
hope it helps
Answer:
Hi there the answer will be (3,11)
Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.
2x+5=3x+2
Then you subtract 2x on both sides to get the x's on the same side
and you get 5=x+2
Then you subtract 2 on both sides, and you get x to equal to 3
then you plug x into any equation to get y to equal 11
y= 2(3)+5
The formula for area is pi x r^2 (pi times radius squared) so, for number 7 youre given the radius or "r", which is half the length of the inside of the cirlce. On a calculator: you would do 8 times 8 (8^2) because that's the radius squared and then you should get 64 and times 64 by 3.14 or use the pi button depending on what your teacher prefers you to use.
When you're given diameter or "d" which represents the is equal to the radius times 2. So, for example, number 8 the diameter is 26 so, the radius is 13. Use the formula for area just like in number 7 to find the area of this circle.
Make sure you pay attention to what information youre given (whether its "d", Diameter, "r" or radius. Use those two lists of steps for solving numbers 7 through 12.
For numbers 13-15: use the number (22/7) instead of 3.14 or the pi button on your calculator and do the same steps!!!!!
Let me know if you still need help after this:) happy math solving!
