Answer: 178.31
Step-by-step explanation: subtract 574.54 by 396.23
The percentage of vehicles passing through this construction zone that are traveling at a speed of 50 and 57 miles per hour
X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)
I’m not 100% sure this is correct, because I’ve never done these before, but try 12, this is the answer I got from a reliable app that I usually use
Orange is 9.
so 9/(7+4+9 ) times 100.
the answer is 45%
