Answer:24 = 24x

Step-by-step explanation:Cross multiply:

2 * 12 = x * 24

Simplifying

2 * 12 = x * 24

Multiply 2 * 12

24 = x * 24

Reorder the terms for easier multiplication:

24 = 24x

Solving

24 = 24x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-24x' to each side of the equation.

24 + -24x = 24x + -24x

Combine like terms: 24x + -24x = 0

24 + -24x = 0

Add '-24' to each side of the equation.

24 + -24 + -24x = 0 + -24

Combine like terms: 24 + -24 = 0

0 + -24x = 0 + -24

-24x = 0 + -24

Combine like terms: 0 + -24 = -24

-24x = -24

Divide each side by '-24'.

x = 1

Simplifying

x = 1

What is the highest common factors and lowest common multiple of 36 and 84 using prime factors

krok68 [10]

Answer:

The corresponding divisor (12) is the GCF of 36 and 84.

2nd answer

LCM = 252

Step-by-step explanation:

Divide 84 (larger number) by 36 (smaller number). Since the remainder ≠ 0, we will divide the divisor of step 1 (36) by the remainder (12). Repeat this process until the remainder = 0. The corresponding divisor (12) is the GCF of 36 and 84.

2nd answer step

Find the prime factorization of 36 36 = 2 × 2 × 3 × 3 Find the prime factorization of 84 84 = 2 × 2 × 3 × 7 Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 2 × 2 × 3 × 3 × 7 LCM = 252
