The first one is correct because that one shows how many times you drank milk today but the rest show how many times you drank milk yesterday.
100 divided by 2 is 50 and then divided by 6 is 8.333333 but you just round that to 8$.
Step-by-step explanation:
is it's total displacement divided by the total time taken.
The perimeter of RSTU can be calculated alone without the help of MNPQ. It would be just 2(4) + 2(3) = 14 units. However, it would be much sensible if you want to find the parameter of the bigger rectangle. Since they are similar, you could use ratio and proportion.
(length/width)∨MNPQ = (length/width)∨RSTU
(x/9) = (3/4)
x = 6.75 units
Thus the perimeter of MNPQ is 2(6.75) + 2(9) = 31.5 units
X - the cost of one night´s lodging
y - the cost of a meal
3 x + 6 y = 132
3 x + 2 y = 109 / * (-1)
-----------------------------
3 x + 6 y = 132
-3 x - 2 y = - 109
-----------------------
4 y = 23
y = 5.75
3 x + 34.50 = 132
3 x = 97.50
x = 97.50 : 3
x = $32.50
The cost of one night´s lodging is $32.50.
