Two numerical patterns are shown below: Pattern A: 4, 8, 12, 16, 20 Pattern B: 8, 16, 24, 32, 40 Select the statement that describes the numerical patterns. The terms in Pattern B are one half the value of the corresponding terms in Pattern A. The terms in Pattern A are one half the value of the corresponding terms in Pattern B. The rule for Pattern B is "multiply by 4." The rule for Pattern A is "multiply by 2."

The statement that best describes the numerical patterns is;

The rule for mapping Pattern A to Pattern B is "multiply by 2"

Step-by-step explanation:

The given two numerical patterns are;

Pattern A: 4, 8, 12, 16, 20

Pattern B: 8, 16, 24, 32, 40

Therefore;

The ratio of the corresponding terms of Pattern B and A are;

8/4 = 16/8 = 24/12 = 32/16 = 40/20 = 2

We multiply a value in pattern A by 2 to obtain a corresponding value in Pattern B

Therefore the rule for mapping Pattern A to Pattern B is "multiply by 2".

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
