You are going to take a 10-question True/False test. How many ways can this test be answered if leaving questions blank is a viable option for each question?

59049 ways

Step-by-step explanation:

We are told one could answer true, false or have the option of leaving the question blank.

Now, for each question, it means that there are 3 ways to answer it.

Thus for 10 questions, total number of ways to answer will be; 3^(10) = 59049 ways

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
