Answer:
x=−7
Step-by-step explanation:
Step 1: Add 5 to both sides.
−3x−5+5=16+5
−3x=21
Step 2: Divide both sides by -3.
−3x/−3=21/−3
No image shown but just remember that percentage is out of 100
0.03 is 3%
I'm assuming the 59% achievement means, markup, so hmmmm well, if the bananas cost him $0.24 or 24cents per pound, so a markup of 59% is just 59% of 0.24 then.
whatever% of anything is just (whatever/100) * anything.
therefore, 59% of 0.24 is just (59/100) * 0.24, or 0.1416.
so, if we add 0.1416 to the 0.24, the selling price will be 0.3816, or just 38cents per pound of bananas.
Set up a proportion.
pounds / milligrams of medicine
195/279 = 130/x
195x = 279 times 130
195x =36,270
x = 36,270/195
x = 186
A patient weighing 130 pounds needs 186 milligrams of medicine.
That answer would be: 987.6666..... (6 repeating)
