The answer is
1.6x-(x-2.8)=(0.2x+1.5)-0.7
1.5-0.7
1.6x-(x-2.8)=0.2x+0.8
1.6x-x
0.6x+2.8=0.2x+0.8
2.8-2.8 0.8-2.8
0.6x=0.2x-2
0.6x-0.2x 0.2x-0.2x
0.4x=-2
0.4x/0.4 -2/0.4
X=-5
Let s = sale
Let h = hours
The ratio is s to h, which can be written as a fraction as 24/6.
Each means to multiply I dont know if thats the word you are asking to us to define
I believe the answer is -6.3
my explanation is because -6.3 is less than -6.1 so technically it makes it smaller. if you were to add to -6.3 you would get -6.1 on the x axis.
Q10 A20 i think
