Destiny has 4*.49 = 1.96 L of acid. In order for the 1.96 L of acid to be 14% of the solution, there must be 1.96/.14 = 14 L of solution.
Destiny must add 14 L -4 L = 10 L of water to make the desired solution.
Answer:
Step-by-step explanation:
Do cross multiplication
Divide both sides by 12

The answer is 8 and 13
<span>
y = ax + b
y = 4, x = 1 </span>⇒ 4 = a + b
y = 6, x = 3 ⇒ 6 = 3a + b
Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3
So, the function rule is: y = x + 3
Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13
x y
1 4

Answer:
False.
Step-by-step explanation:
To see if these sides can form a right triangle, all we need to do is see if the following equation holds where is the larger measurement. it doesn't really matter which you assign as 5 or 8.
So I'm choosing the following .
has to be 12 because 12 is the largest.
Now we got to see if holds.
That is, we need to see if holds.
That's totally false. 89 is definitely not 144 so 5,8, and 12 cannot be put together to form a right triangle.
