Answer:
There are 3 green marbles in the box.
Step-by-step explanation:
15% = 0.15
To figure out how much 15% of 21 is, you must multipl the decimal form of the percentage by the whole number. This will give you how much of that number that percentage is.
0.15 * 21 = 3.15
But you can't have 0.15 of a marble, so you must round as well.
3 green marbles in the box.
Answer:
20x+68
Step-by-step explanation:
<span>Subtract 7 from both sides of the equation. Check: Substitute -4 for x in the original equation. If, after the substitution, the left side equals the right side, your answer is correct. ( -4 ) + 7 = 3 </span>
P=pounds
So we have the equation 4.3p+1.7p=41.94
combine like terms and we have 6p=41.94
divide both sides by 6 and we get p=6.99
$6.99 is your answer! :D
