So this is a solution problem the answer is 3/4 cups or 75% milk and 1/4 cups or 25% cream, here's why:
m = milk
c = cream
m + c = 1
This is because when you add milk and cream then you get one cup of solution
.02m + .18c = .06
When you add together the percentages the goal is to have .06 or 6%
100m + 100c = 100
2m + 18c = 6
I do this to make it easier to solve
200m + 200c = 200
-200m - 1800c = -600
The "m's" cancel out
-1600c = -400
c = 1/4 or .25 or 25%
Now we add c back in
m + 1/4 = 1
Solve for m
m = 3/4
Thus: 3/4 milk and 1/4 cream

Answer:
The customer can form 160 different kits in the perfumery
Step-by-step explanation:
Here, we are interested in knowing the number of different kits a customer can form in the perfumery.
Now since each kit contains 1 each of moisturizers, soaps and perfume, what will happen is that we are going to select one each of the options
This means we shall be selecting 1 out of 5 soaps, 1 out of 8 moisturizer and 1 out of 4 perfumes
Mathematically, the number of ways we can select r items out of a total of n can be calculated as nCr
Applying this in the case we have;
It would be;
8C1 * 5C1 * 4C1
where
8C1 = 8, 5C1 = 5 and 4C1 = 4
Thus the number of options we have will be
= 8 * 5 * 4 = 40 * 4 = 160 kits
Answer:
No
Step-by-step explanation:
The sum of the smaller sides is not bigger than the largest side, 122. ( 31 + 89 = 120 < 122)
Let's eliminate x. Mult the first eq'n by 4, obtaining
-4x + 8y = 36
Now add the 2nd equation to this result:
-4x + 8y = 36
4x + 5y = 3
--------------------
13y = 39, so y = 3.
Subst. 3 for y in the 2nd equation and solve the result for x:
4x + 5(3) = 3 => 4x = -12 => x = -3. Solution is (-3,3).
