Answer:
inches.
Step-by-step explanation:
The level of a lake was 8 inches below normal.
Now, it is given that the water level decreases
inches in June and
inches more in July.
Therefore, the new level of water with respect to the normal level will be
= - 8 - 1.25 - 2.375
= - 9.625 inches
=
inches. (Answer)
Answer:
30
Step-by-step explanation:
So we begin by assigning variables to each side with:
DE = x
EF = y
DF = z
Now we start listing a system of equations from what is given:
x+y+z=81
x=2y
x-4=z
Once we solve that with substitution, we get the result of:
x=34
y=17
z=30.
Since z is the length of DF, the length of DF is 30.
