Answer:
.75 mg
Step-by-step explanation:
.25 * 3 = .75 mg
I'm guessing that the two expressions are for separate equilateral triangles.
If so, the equations would be:
3(3x-14)=180
3(x+4)=180
to solve the first equation, divide by 3:
3x-14=60
then, add 14 to both sides:
3x=74
lastly, divide both sides by 3:
x=24.667
to solve the second equation, divide both sides by 3:
x+4=60
then, subtract 4 from both sides:
x=56
Step-by-step explanation:
This question is a little ambiguously worded, however I assume the answer would simply be:
$500 - $112 - $28 = the amount he has left.
Hope this helped :))
