220 miles in 4 h = 55 mph multiply this by 5280 to get feet per hour then divide this by 60 to get ft/min
5 - x = 12
We're essentially just trying to get "x" onto its own side.
So, simply subtract 5 from both sides.
-x = 12 - 5
Simplify.
-x = 7
Now, divide both sides by -1.
x = -7

Answer:
We need 8 ounces of solution A and 32 ounces of solution B.
Step-by-step explanation:
We are given that a scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt.
She knows that Solution A is 40% salt and Solution B is 65% salt.
- First condition states that she wants to obtain 40 ounces of a mixture that is 60
% salt, that means;
A + B = 40
B = 40 - A ------------ [Equation 1]
- Second condition states that Solution A is 40% salt and Solution B is 65% salt, that means;
{from equation 1}
A = = <u>8 ounces</u>
Now, putting value of A in equation 1, we get;
B = 40 - A
B = 40 - 8 = 32 ounces
Hence, we need 8 ounces of solution A and 32 ounces of solution B.
Answer:
Step-by-step explanation:
There are 2 factors of 5, so you have 5^2
There are 3 factors of x, so you have x^3
There is a single y, so you have y
