Answer:
Step-by-step explanation:
M' = (8,2)
A' = (7,6)
T' = (2,6)
H' =(3,2)
If this is a reflection across the y axis, then all that will change is the x value. You have to read that carefully to make sure you understand it.
Notice that T = (-2,6). All that happens is the the minus becomes a plus.
To get the answer, you divide 2540 by 25, which gets you 101.6. Then, you would multiply 101.6 by 23 to get your answer, which is 2336.8.
To find miles per hour you divide the number of miles by the number of hours
(7 1/2)/(3/8) = (15/2)(8/3) = 20 mph
Answer: x children and (481-x) adults.
1.25x +2.25(481-x) = 865.25
1.25x +1082.25 -2.25x =865.25
x= 217
so 217 children and 481-217 = 264 adults
