Pls help

(B) 2x + 1

Step-by-step explanation:

1. First, we have to solve the equation for the variable, z.

2. (Solving)

Step 1: Multiply both sides by 3z.

Step 2: Multiply both sides by 6x.

Step 3: Divide both sides by 15abc.

3. Now, the question is asking for z + 1. Since we now know that z = 2x, the equation will become 2x + 1 otherwise known as option B.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
