Answer:
Yes, reflecting a shape across the x-axis and then rotating it 90° clockwise about the origin gives the same results as reflecting it across the y-axis followed by rotating it 90° counterclockwise about the origin. This means these two sequences of transformations are equivalent.
Step-by-step explanation:
12 sessions.
EXPLANATION:
each session is 1 3/4 hours.
We need enough sessions for 21 hours.
the equation is 1 3/4 x f = 21
using the multiplication property of equality, we can do 21 divided by 1 3/4
The answer is 12 sessions.
Hope it helps!
90+80+90+x=360
260+x=360
x=100
