Answer:
44%
Step-by-step explanation:
So you have 2 bottles. One bottle is 8ml and is 80% acid. the other is 12 ml and is 20% acid.
This means there's 6.4 ml of acid in bottle 1(8*0.8) and 2.4 ml of acid in the other one(12*0.2).
The total amount of liquid is 8+12 = 20
The total amount of acid is 6.4+2.4 = 8.8
Percentage of acid in the new solution is 8.8/20 = 0.44 = 44%

Use distributive property: a(b - c) = ab - ac

Answer:\
To be a right triangle, the hypotenuse^2 must equal side1^2 + side2^2
Only set 2 meets these conditions
8, sq root (29), sq root (35) then squaring these:
64, 29, 35
64 = 29 + 35
Answer:
Many expressions would satisfy this set. One example would be y = 7x + 2
Step-by-step explanation:
To find this, give x a random coefficient, for this purpose, we'll use 7.
y = 7x + c
Now plug in and solve to get the constant.
-33 = 7(-5) + c
-33 = -35 + c
2 = c
Now model the equation.
y = 7x + 2
