MrRa [10]

Answer:

x < -20

Step-by-step explanation:

x / -4  + 14 >20

Subtract 14 from each side

x / -4 +14-14 > 20 -14

x / -4 > 6

Multiply each side by -4, remembering to flip the inequality

x / -4 * -4 < 6 * -4

Solve for all values of x in simplest form. 9-4|3+5x|=5
Zinaida [17]

Answer:

x=-2/5\text{ or } x=-4/5

Step-by-step explanation:

So we have the equation:

9-4|3+5x|=5

First, subtract 9 from both sides:

-4|3+5x|=-4

Divide both sides by -4:

|3+5x|=1

Definition of Absolute Value:

3+5x=1\text{ or } 3+5x=-1

Subtract 3 from both sides:

5x=-2\text{ or } 5x=-4

Divide both sides by 5:

x=-2/5\text{ or } x=-4/5

And we're done!

 Jeremy and Randell are brothers and each are trying to raise money for summer camp.
To help Jeremy raise money, his parents told him he could wash each of their cars once a week for $20.00 each. He has already earned $640.00. The football camp that he wants to attend costs $1,469.00.
To help Randell raise money, his parents told him he could mow the grass for them and both sets of grandparents once every 2 weeks and earn $28.00 for each lawn he mows. He has already earned $728.00. The lacrosse camp that he wants to attend costs $1,701.00.
If Jeremy and Randell each earn enough money to attend the camps of their choice, then from this point on (randell) needs to complete (idk what would got here) more chores than(jeremy)

is it asking you to fill in the blanks with their names if so i think it would be this.

Solve: please answer as fast as possible <br><br> -2 + 6 &lt; 4
Naya [18.7K]
-2 + 6 < 4 equals 4 < 4.

First, simplify -2 + 6 to get 4. / Your problem should look like: 4 < 4.

If you are looking for the solution to this problem, there is none since 4 < 4 is false.
