Answer:
this means she ate an average of 30 raisins each day
so she ate 30 on the third day
so the amount she ate each day is like this
1. 16
2. 23
3. 30
4. 37
5. 44
16 + 23 +30 +37 +44=150
500 miles / 20 gallons = 25 miles / gallon
25 miles * 18.5 gallons = 462.5 miles / one tank of gas
Answer:
The coordinates are x = -1 and y = -2.
Step-by-step explanation:
Given:
Equations are 2x-4y=6 and 3x+y=-5.
Now, to find the coordinates.
...........(1)
...........(2)
So, first we solve the equation 1 to get the value of
.

Subtracting both sides by
we get:

Dividing both sides by 2 we get:

Now, we put the value of
in equation 2 to get
.




On solving the whole equation we get :

And, now putting the value of
in equation (1) we get
:





on solving we get:

Therefore, the coordinates are x=-1 and y=-2.
Answer:
Step-by-step explanation:
V = 12*x²*y
a) DV/Dt = 12*x²*Dy/Dt
b) DV/Dt = 24*x*y*Dx/Dt
c) DV/Dt = 24*x*y*Dx/Dt * 12x²Dy/Dt
