Let's replace every copy of x with 7 and simplify.
Which is clearly false. This is probably the set of steps you followed to get "no solution".
Why is there no solution? Well let's subtract 9 from both sides to isolate the square root
Recall that the result of a square root operation is never negative. The range of 
and 
is the set of nonnegative numbers. There is no way we can have the left hand side result in -6
If there was a negative sign out front the square root and we have this instead
then the answer would be x = 7
Unfortunately, there isn't such a negative sign, so we stick with "no solutions".
4/5 x 7/10=28/50
7/10+28/50=35/50+28/50=63/50 which is not enough to make 1-1/2 miles

Answer:
Y=5x+7
Step-by-step explanation:
I know trust me.
1x should be your answer cause if your exponent is 0 then your answer automatically turns to a 1
Answer:
Step-by-step explanation
Let the number be y
y doubled = y×2=2y
2y increases by 3 = 2y+3=
2y +3 is more than 6 but less than 20
2y+3 > 6
2y+3< 20
Solve for y
2y>6-3
y>3/2
2y+3<20
2y<20-3
2y<17
y<17/2
