Answer:

8x + 12y ,4(2x + 3y)

Step-by-step explanation:

here's your solution

=> to find the equivalent we need to simplify

this

=> 4(2x + y + 2y)

=> 4(2x + 3y)

=> 8x + 12y

=> we can also take common from it

=> 4 (2x + 3y)

hope it helps

How many grams of 0.5% hydrocortisone cream must be mixed with 180 g of 2.5 % cream to make a 1 % w/w hydrocortisone cream? HINT

Sophie [7]

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.

What is the equation of the line passing through the points (Two-fifths, StartFraction 19 Over 20 EndFraction) and (one-third, S

Elan Coil [88]

Answer:

You have to find the slope first. Which is y1-y1 divided by x1-x2

Then you find the y-intercept which you take the slope for m like for example if you find the slope, 2, then the equation should be y=2x+b. You take the coordinates on the problem and put them on the y or x on the equation. Then when you find the y-intercept you add it to the equation like for the example that I used above, you have to put the y-intercept on b. So if the y-intercept is 5 then the equation would be y=2x+5.

Find the future value of $50,000 at 6% compounded semiannually for ten years.

Nookie1986 [14]

Answer: $ 90305.56

Step-by-step explanation:

To find the future value of the amount, use the compound interest formula as follows:

A = P( 1 + i/m)^mn

Where; A = Future amount after n years;

P = Principal amount or amount deposited which is equal to $50, 000 in this question.

i = interest rate charge which is 6% in this case

m = number of times compounded per year, thus, m = 2 in this case since it is compounded semi-annually.

n = number of years which is 10 years in this case.

Substituting in the equation:

A = 50 000( 1 + 0.06/2) ^ 2(10)

= $ 90305.56
