Answer:
1/3
Step-by-step explanation:
1/2 * 2/3
1 * 2 = 2 (numerator)
2 * 3 = 6 (denominator)
2/6 or 1/3 as simplest form
Is x = 6 a solution to the equation 5(x – 3) = x + 13? Follow the steps to find out. 1. Rewrite the equation 5(x – 3) = x + 13 with 6 substituted for x. Write a question mark over the equal sign to show that you're testing to see if the equation is true. 2. Simplify both sides. Show your work. 3. Is x = 6 a solution to the equation? Why or why not? 4. Find a value of x that is a solution to 5(x – 3) = x + 13. Describe how you found the solution.
Answer:
x = 7Step-by-step explanation:
Testing if 6 is the solution:
5(x – 3) = x + 135(6 - 3) ? 6 + 135(3) ? 1915 ≠ 196 is not a solution
---------------------------------------------
Solving for x:
5(x – 3) = x + 13 ⇒ open parenthesis5x - 15 = x + 13 ⇒ isolate variable5x - x = 13 + 15 ⇒ simplify4x = 28 x = 28/4x = 7Answer:

A cube measuring 6cm a side is painted red, and then cut up into 216 smaller cubes each 1 cm cubed in volume. How many of the smaller cubes are painted on exactly one surface.
Answer:
216 cm^3.
Step-by-step explanation:
All cubes on the external sides with only a single surface exposed to the paint can be ... If this cube is cut into 216 equal small cubes, how many small cubes will have no ... So let's find out first all cubes which have at least one face coloured ... Let us consider a cube having each side of 6cm then it's volume will be 216 cm^3.
PLEASE HURRY!! What is the location of point A?
Answer:
(-2,1) or Option 4
Step-by-step explanation:
So the way I did it is you look at the row x first then y. So when looking at row x you see that point A is located at -2. Then when you are looking at column y you see that point A is at 1.
So (-2,1) is your answer.

Samuel is buying a pair of boots with an original price of $80.
• Store A is offering a 25% discount off the original price of all boots.
• Store B is offering a $10 discount off the original price of all boots.
Based on this information, which statement is true?
The best deal was given by store A. Because the price at store A is less than store B.
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Samuel is purchasing a couple of boots with a unique cost of $80.
Store A is offering a 25% markdown off the first cost, everything being equal. Then the price of the boot will be given as,
⇒ (1 - 0.25) x $80
⇒ 0.75 x $80
⇒ $60
Store B is offering a $10 markdown off the first cost, all things considered. Then the price of the boot will be given as,
⇒ $80 - $10
⇒ $70
Based on this information, the best deal given by store A.

Answer:
x = 6
Step-by-step explanation:
Alternate angles are congruent.
7x - 9 = 3x + 15 {Subtract 3x form both sides}
7x - 3x -9 = 15
4x - 9=15 {Add 9 to both sides}
4x = 15+9
4x = 24
x = 24/4
x = 6
