Answer:
x<15
Step-by-step explanation:
-(x - 1) + 20 <-3(x - 3)
-x + 1 + 20 <-3x + 9
-x + 21 < -3 + 9
-x < -3 + 9 - 21
-x÷ -1 < -15 ÷ -1
x > 15
For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
Answer:
1.8
Step-by-step explanation:
1.176 rounds up because the hundredths place is more than 5. The thousandths place doesn't matter.
3 < sqrt(12) < 4
6 < sqrt(40) < 7
So the only integers between those square roots are 5 and 6
Add them together.
