1X+8X=90
9X=90
X=10
so one of them is 10 and the other one is 8 times 10 which become 80
Step-by-step answer:
It is a glide reflection.
The order of sliding and reflection is not important if the gliding is parallel to the line of reflection, which is the case here.
So the equivalent is translate five units down, and then reflect over the y-axis.
Note in general that rotations will not be equivalent to an odd number of reflections. So looking for an equivalent, look for reflection.
$120 and the ratio is 3:2
$200 6:4 and half
The answer is 33%. To work out a percentage increase we work out the increase, so the difference between 12 and 16 is 4. We divide this by the original amount (12) and times it by 100, which gives you 33.333(recurring) which is rounded to 33%. Hope this helps!
