Answer:
you have the answer correct actually
Step-by-step explanation:
First you need to isolate the variable so for #1 I would add 2t on both sides and add 3 on both sides. That makes the inequality -4t<-16. Then divide both sides by -4 to get t<4. This means that t is less than 4 so you need to draw an open circle on four on the number line and draw an arrow pointing to everything less than 4. ( If the inequality is equal to and less than/ greater than a # shade in the circle.)
Answer:
x=6
Step-by-step explanation:
The given equation is
We need to find the value of x for which the given statement is true.
Using distributive property we get
Add 8 on both sides.
Divide both sides by 5.
Therefore, the given statement is true form x=6.
Answer:
x-31(Greater than or equal to)66 -->x(greater than or equal to)97
