18. Solve b-9>20. I don't know how to solve it.
20.Julia is allowed to watch no more than 5 hours of television a week. So far this week, she has watched 1.5 hours. Write and Solve an inequality to show how many hours of television Julia can still watch this week.
HELP PLEASE AND FAST JUST TELL ME IF THEY ARE WRONG OR RIGHT AND IF THEY ARE WRONG THEN PLEASE WORK IT OUT FOR ME OR BREAK IT DOWN.
I wish I knew what they are!!!!!!!!
I Know That #20 Is This
20.let x = amount of hours watching tv
1.5 + x < 5
x < 5 - 1.5
x < 3.5
< being less than or equal to.
Thanks Do you know any more?
Do you know the answers to the other questions I asked?
No I don't know Sorry :(
What are the answers to this test 1-17
13. The equation is 10(x-2) = 10x.
To solve this equation, first distribute the 10 on the left side of the equation: 10x - 20 = 10x.
Now, subtract 10x from both sides of the equation to eliminate the variable on one side: -20 = 0.
We can see that -20 is not equal to 0. Therefore, there are no solutions for this equation.
So, the answer is B.) no solution.
14. The equation is -2(y-3) = 2y-6.
To solve this equation, first distribute the -2 on the left side of the equation: -2y + 6 = 2y - 6.
Next, add 2y to both sides of the equation to eliminate the variable on one side: 6 = 4y - 6.
Now, add 6 to both sides of the equation: 12 = 4y.
Finally, divide both sides of the equation by 4 to solve for y: y = 3.
So, there is one solution for this equation.
The answer is A.) one solution.
18. The inequality is b - 9 > 20.
To solve this inequality, first add 9 to both sides of the inequality: b > 29.
So, the solution to the inequality is b > 29.
Julia can watch any number of hours greater than 29 hours of television this week.
20. The inequality can be written as 1.5 + x ≤ 5, where x represents the number of hours Julia can still watch.
To solve this inequality, first subtract 1.5 from both sides of the inequality: x ≤ 3.5.
So, Julia can still watch a maximum of 3.5 hours of television this week to stay within her allowed limit.
I hope this helps! Let me know if you have any further questions.
