19+17+15+13+7+5+3+1 Which of the following is another way of writing the sum of the numbers shown?

A.4×18
B.4×19
C.4×20
D.4×21

C

4×20=80

19+17+15+13+7+5+3+1 = 80

4 x 20

Step-by-step explanation:

Step 1. Add all the numbers 19+17+15+13+7+5+3+1 = 80

Step 2. Find the equation that matches the sum. Eliminate the answers you know are wrong. 4 x 20 = 80 is another way of writing all those numbers.

Hope this helps and thanks :)

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
