Answer:
Step-by-step explanation:
Squaring both sides of the equation would give 
which then simplifies to 
We can then subtract 7 from both sides to get 
Then we can subtract x from both sides, which cancel out and we get 
Then we need to divide both sides by -2 to get 
Then we need to square both sides 
to get rid of the square root to get 9 = x + 6
Then finally subtracting 6 from both sides we get 3 = x
I think it's B not 100% about it tho
25/100=1/4
a) you bought 1 1/4 pound of ham
b) $6.50
1.25 x $5.20=$6.50
5
8
6 or 7
Just taking a guess
40 liters.....30% is yellow tint
0.30(40) = 12 liters are yellow
if u add 6 liters....(12 + 6) = 18 liters are now yellow...and since u added 6 liters, ur total mixture is now 46 liters.
18/46 = 0.39 = 39% <===
