Answer:
System of equations
160 = 2W + 2L
W = L - 16
Solution to system of equations
W = 32 ft
L = 48 ft
Explanation:
The width is 16 feet less than the length, so the appropriate equation for that is ...
... W = L - 16
Using this expression for W, we can substitute into the equation for perimeter:
... 160 = 2(L - 16) + 2L
... 160 = 4L -32 . . . . . . . collect terms
... 192 = 4L . . . . . . . . . . add 32
... 48 = L . . . . . . . . . . . . divide by 4
... W = 48 -16 = 32 . . . . find W using the relation with L
Length is 48 ft; width is 32 ft.

Answer:
29.03g
Step-by-step explanation:
The total mass of the jar and marbles combined is 1.281kg, or 1281g. Subtract the mass of the jar from this to find the total mass of the marbles (1281g - 236g = 1045g). Then, divide this number by 36 to find the mass of each marble (1045g / 36 = 29.03g).

Answer:
(6, 4)
Step-by-step explanation:
y-4=-2(x-6) <=> y-y1 = s(x-x1)
(x1, y1) => (6, 4)
If every minute 3 poles past and poles are 1/4 mile (0.25 mile) apart;
3x0.25 = 0.75
Train moves 0.75 mile/per minute
If you want the train's speed per hour, then;
x = 60x0.75
x= 45miles per hour is the speed of the train
