We need the picture to answer so if you could take a picture and put it on the question
Answer:
We need 540 grams of 0.5% hydrocortisone cream
Step-by-step explanation:
Lets call x the amount of grams needed. This means that the combined cream will have 180+x grams. We want x such that
x * 0.005 + 180*0.025 = (180+x)*0.01
Hence
0.005x + 4.5 = 1,8+0.01x
Lets put the x in the same side and take common factor
4.5-1.8 = 0.01x-0.005x
2.7 = (0.01-0.005)x = 0.005x
As a result
x = 2.7*0.005 = 540
We need 540 grams.
1500 move the decimal over 2 places and u have ur answer
Let's represent Ben's current age by x and his age in 16 years, x+16.If in 16 years, his age will be 3 times his age now, the equation is x+16=3x
x+16=3x
x-x+16=3x-x
16=2x
16/2=2x/2
8=x
Therefore Ben is 8 years old.
Answer:
$1 : ~2.1666667 ounce package
<em>~</em><em> </em><em>means</em><em> </em><em>about</em><em>;</em><em> </em><em>estimation</em>
How we solve this
$6 (÷6) -> $1
13 (÷6) -> 2.16666667
We divide the exact number by the number of the price to get the proportion of each ratio.
