Answer:
Total amount spent= $32.04
Step-by-step explanation:
If a full tank carries 15 gallons and Irene's car had only 6.1 gallons, it means that it is empty by ; (15-6.1 )= 8.9 gallons.
Therefore , she needs 8.9 gallons to fill the tank.
Cost of gas per gallon=$3.60
Total amount spent to fill the tank would be = # of gallons * cost per gallon
Total amount spent= 
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3
The answer is D 81 that the answer to the question
Answer:
the square root of -1 is actually "i"
Step-by-step explana
Remove the brackets
6 - t + 7 - t - 4 + t = 0
Eliminate the two opposite t because they cancel out to each other
6 + 7 - t - 4 = 0
Add and subtract
6 + 7 - 4 = 9
Thus:
9 - t = 0
Bring the 9 over to the 0 to isolate the -t
-t = 0 - 9
Calculate:
-t = -9
To get rid of the negative on the variable we have to divide it by -1 to make it positive bc negative divided by negative equals positive. Since we are dividing -1 to the -t we also have to divide -9 by -1.
t = 9
