B I think I’m not sure tbh
<u>Answer</u>:
360 Minutes Long
<u>Step-by-step explanation:</u>
There are 60 minutes in an hour. Multiply 60*6, and you get 360 minutes.
The distributive property combines multiplication with addition and multiplication with subtraction together in order to simplify the equation. It is named as such because the number outside of the open and close parenthesis are distributed to the terms inside. Say for example, the equation given is 5(2x - 3). According to the distributive property, you distribute 5 by multiplying to each of the terms inside the parentheses. The solution would be: 5*2x + 5*-3 = 10x - 15. As you can see, it involved multiplication with addition and subtraction. Generally, you just have to add all the terms while making sure you carry the sign of the integer along when you multiply them just as shown in my example.
Given that total volume of the solution = 12 quarts
Let volume of water added = x quarts
Then volume of 30% vinegar = (12-x) quarts
Given that x quarts of 0% water is mixed with (12-x)quarts of 30% vinegar to obtain 12 quarts of 25% solution
So we can write equation as:
[0% of x] + [30% of (12-x)] = [25% of 12]
or 0x + 0.30(12-x) = 0.25*12
or 0 + 3.6-0.30x = 3
or -0.30x = 3-3.6
or -0.30x = -0.6
x=2
Hence answer will be 2 quarts of water.
Answer:
It will take 8 hours for Frank and Mary to get to the beach
Step-by-step explanation:
Step 1: Give expression for calculating
d=s×t
where;
d=distance traveled i miles
s=speed in miles per hour
t=time in hours
in our case;
d=520 miles
s=65 miles per hour
t=unknown
Step 2: Solve for the unknown, t
In order to solve for t, the expressions can be rearranged as follows ;
t=d/s
replacing values for d and s;
t=520/65
t=8 hours
It will take 8 hours for Frank and Mary to get to the beach
