Answer:
$0.57
Step-by-step explanation:
7 pound = 4 $
1 pound =4/7 $
=0.57$
For 3 days....
option 1 : 25(3) + 0.10m = 75 + 0.10m
option 2 : 60(3) = 180
180 < 75 + 0.10m
180 - 75 < 0.10m
105 < 0.10m
105 / 0.10 < m
1050 < m.....this is minutes, we need hrs
1050/60 < m
17.5 < m.......the guest would have to spend more then 17.5 hrs
Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.
0.8 x 103 because the first number cant be less then 1 or more then 9 you would have to move the decimal to make the equation correct
(9 - 7 × 3 + 4)²
(9 - 21 + 4)²
(9 - 17)²
(-12)²
144
