"4 t plus 6 is greater than or equal to ten"  needs to be converted to symbolic form, involving the "equal to or greater than" symbol.  Can you do this conversion, Marrero?

mathmale · Answer

Try to build on what you learned in the previous problem, OK?

is it b?

mathmale · Answer

sorry, no.
Would you mind showing all of your work, please?  That way i could know exactly how best to help you.

anonymous · Answer

i just dont understand it

mathmale · Answer

Translate "4 t plus 6 is greater than or equal to ten" into symbols.
What does "4t plus 6" look like in symbols?  remember that that "plus" means "addition."

anonymous · Answer

4t + 6

mathmale · Answer

Right.  And:  "4 t plus 6 is greater than or equal to ten."
So, 4t + 6 = what?

anonymous · Answer

the t is still there

anonymous · Answer

4 + 6 = 10

mathmale · Answer

Except that you still have that " t " in there.

4 + 6 = 10   NO

4t + 6 = 10    YES

subtract 6 from both sides of this equation.  Then solve it for t.

anonymous · Answer

ok it makes 4

anonymous · Answer

t is 4

mathmale · Answer

If 4t + 6 = 10,
and we subtract 6 from both sides,
we get:

   4t=4

Divide both sides by 4 (why?)

anonymous · Answer

idk

mathmale · Answer

4t     =     4
----       ----
   4             4

Simplify both sides, please.

anonymous · Answer

it makes 2

mathmale · Answer

$$\frac{ 4t }{ 4 }=t, so. \frac{ 4 }{ 4 }=?$$

mathmale · Answer

Remember, treat each side of the equation separately.

anonymous · Answer

1

anonymous · Answer

4/4 = 1

mathmale · Answer

Right, and so (4t/4) = t = 1.

Now, because the original problem statement said "greater than or equal to," write$$t \ge 1$$ and also determine which of the four possible asnwers is correct; it is not B.
