Subtract the blue caps:

25-11 = 14 caps are either white or green.

Let green = X

white = X +2

Green +  white = 14:

x + x +2 = 14

Combine like terms:

2x +2 = 14

Subtract 2 from both sides:

2x = 12

Divide both sides by 2:

x = 6

There are 11 blue caps, 6 green caps and 8 white caps.

Solve the equation for y.<br><br> 4.2x−1.4y=2.1
Vlada [557]

Answer:

y=3x- 3/2

Step-by-step explanation:

4.2x−1.4y=2.1

Subtract 4.2x from each side

4.2x-4.2x−1.4y=-4.2x+2.1

-1.4y = -4.2x +2.1

divide each side by -1.4

-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y

y=3x- 3/2

Emily added 5 grams of water into 20 grams of 50% salt solution.
atroni [7]
Answers:
She made ___25___ grams of ___40___% salt solution

------------------------------------------------------------------

The given info "20 grams of 50% salt solution" tells us that we have 10 grams of pure salt
Since 50% of 20 = 0.50*20 = 10
Put another way, we have 10 grams of pure salt out of 20 total so 10/20 = 0.50 = 50% salt solution

The 20 grams of solution updates to 25 grams of solution when we add the 5 grams of water
We don't add any salt, assuming this water is fresh water

So we still have 10 grams of pure salt out of 25 grams now
10/25 = 2/5 = 0.40 = 40% is the new salt concentration
