To determine the location of a point on a graph, the first number of the ordered pair is a x-coordinate which means the first number you would look for would be the horizontal line, or the x-axis. The second number is the y-coordinate which means that you would look on the vertical line, or the y-axis. You would go on the horizontal line first, then from there go up to the y-coordinate and place your point. (I'm sorry if it's long but you can try to shorten it.)
Hope this helped!
Have a nice day!
X+y+z=51
y=2z
z=9+x
subsitute those
x+2z+9+x=51
x+2(9+x)+9+x=51
x+18+2x+9+x=51
4x+27=51
minus 27 both sides
4x=24
divide by 4
x=6
sub back
z=9+x
z=9+6
z=15
y=2z
y=2(15)
y=30
the numbers are
6,30,15
Draw a straight line. Label the left side "0" and then make lines with
"2" "3" and "4".
1/3 means it i 1/3rd of 1. Which means you need to divide everything from 0 - 1 into 2 segments. The first segment on the left side is your 1/3rd spot. The next one is your 2/3rd place, and then finally the 1 is your 3/3 (or one whole.)
9.9
With right triangles you can use the equation a^2 + b^2 = c^2. Since both a and b are 7, that makes it 7^2 + 7^2 = c^2 and from there 49 + 49 = c^2 and then 98 = c^2. Then go find C, you find the square root of 98 which is 9.899494937 or rounded as 9.9
Keep in mind a^2 + b^2 = c^2 only works for right triangles, it won’t work for any other ones.
