Answer:
if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash
so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap
the entire car needs <u><em>3/4 of a bottle of soap</em></u>
Use this exponent property;

So you have

So you should use "

".
0.9 is the answer pick that one that was pretty easy just read the question very carefully

Step-by-step explanation:
Answer:
When (-1,-4) is substituted into the first equation, the equation is true.
When (-1,-4) is substituted into the second equation, the equation is true.
Step-by-step explanation:
The given system is
x-y=3
7x-y=-3
Make x the subject in the top equation to get:
x=y+3
Put x=y+3 in the bottom equation to get:
7(y+3)-y=-3
Expand
7y+21-y=-3
7y-y=-3-21
6y=-24
y=-4
Put y=-4 into x=y+3 to get
x=-4+3=-1
Hence the point (-1,-4) is a solution to both equation
