Answer:

D

Step-by-step explanation:

The solution is B. In each equation, it uses parenthesis to group operations. On the left, each pair repeats one number either 1.6 and 4.2. On the right is written the reduced form by writing the expression with a greatest common factor.

Option A is incorrect since 1.6 is not the GCF which appears in each parenthesis.

Option B is incorrect because the operation in the parenthesis is multiplication and not addition.

Option C is incorrect because 1.6 as a GCF is applied using multiplication.

Option D is correct since 1.6 does occur as a GCF in each parenthesis. It also has written correctly (4.2 +7) since addition is the operation between the parenthesis.

Explain how to solve the equation by reasoning about numbers, operations, and expressions. Do NOT use standard algebraic equatio
Brilliant_brown [7]

Answer:

x=924

Step-by-step explanation:

348 + 926 = x + 350

we have two 2-terms additions in both sides of the equation.

348 and 350 are two <em>similar</em> numbers then x and 926 should be really <em>close</em> numbers.

(due to commutative property of additions 348 + 926 = 350 + x)

<em>since 348 has two units less than 350, then 926 must have two units more than x, and <u>x=924</u></em>

(indirect proportionality)
