Answer: x = 2
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4(x) which is 4x and 4(6) which is 24.
So our equation now reads 4x + 24 = 32.
Solving from here, we subtract 24 from both sides to get 4x = 8.
Then divide both sides by 4 to get <em>x = 2</em>.
Answer:
10 to the 17th power
Step-by-step explanation:
with 10s you just take the number of zeros behind the number and that equals the amount of powers you have. This method does not work with any other number besides 10!!

Answer:
First brand of antifreeze: 21 gallons
Second brand of antifreeze: 9 gallons
Step-by-step explanation:
Let's call A the amount of first brand of antifreeze. 20% pure antifreeze
Let's call B the amount of second brand of antifreeze. 70% pure antifreeze
The resulting mixture should have 35% pure antifreeze, and 30 gallons.
Then we know that the total amount of mixture will be:
Then the total amount of pure antifreeze in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -0.7 and add it to the second equation:
+
--------------------------------------
We substitute the value of A into one of the two equations and solve for B.
