Answer:

3/12 simplified to 1/4

Step-by-step explanation:

When two fractions in an equation have the same denominator, you can easily subtract/add the numerator, so:

9 - 6 = 3

3/12

If you need to simplify your answer, your answer is 1/4

When simplifying this fraction, three is a multiple of 12 and 3 (called the common factor)

3 divided by 3 is 1

12 divided by 3 is 4.

The difference between Sheila and Robbie's ages is 12. The sum of their ages is 42. If Sheila is the younger of the two, how old

Colt1911 [192]

Let's say that Robbie's age is represented by r and Sheila's age is represented by s. Since we know that r is greater than s, we can set up a difference equation of r - s = 12. We also know that r + s = 42. Now, we can simply add the two equations and get that 2r = 54, then finally that r = 54. Therefore, Robbie is 54 years old.

Hope this helps!

<h3>What is congruence in geometry?</h3>

The measurements of the sides and angles of two or more geometrical figures determine their congruence. For example triangle's size is determined by its three sides, and its shape is determined by its three angles.

We have:

The diagram represents an unfolded paper kabuto, a samurai warrior's helmet.

Unfolded paper can be seen in the provided figure. The sheet is square.

The diagonals, in this case, are FN and AK, and the midline is CM and OI. At point R, all of these lines converge.

FR ≅ NR

AO ≅ ON

RC ≅ RO

NO ≅ NM

DV ≅ HV

Thus, option (B) FR and NR, option (C) NO and NM, and option (D) RC and RO are correct.
