Answer:
16 and 4
Step-by-step explanation:
x + y= 20
x -y =12
(add both equal #'s)
2x =32
x = 16
y=4

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
I’m assuming you’re saying with an exponent. 7x^2+5
Answer: <em>You didn't provide the options so unable to know which option is the correct answer</em>
<u>Step-by-step explanation:</u>
x + 2 = 0 ⇒ x = -2
-2 | 4 -2 3
<u>| ↓ -8 20 </u>
4 -10 23
(x + 2)(4x - 10 + )
18 divide by 2 =9 9 divided by 3 x2 = 6 9-6=3 that haven't bloomed
