Answer:
x <-8
Step-by-step explanation:
3-(2x-5) < -4(x+2)
Distribute
3 -2x+5 < -4x-8
Combine like terms
8 -2x < -4x-8
Add 4x to each side
8 -2x+4x< -4x-8+4x
8+2x < -8
Subtract 8 from each side
8-8+2x< -8-8
2x<-16
Divide by 2
2x/2 < -16/2
x <-8
Given ---›
y = -3
&
y = x - 0.8
So,
=> x = y + 0.8
=> x = -3 + 0.8
=> x = -2.2
Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)
Answer:
Let C be the cost price of the article. Then:
C(1+30%)=marked price
So:
C(1+30%)=C(1.3)
=1.3C
If the article is then marked down 35%, then its’ price would be:
1.3C(1–35%)=1.3C(.65)
=0.845 or 84.5% of its’ cost
Then:
0.845–1=-0.155
or, a 15.5% loss on the item
