6 times 5 equals 30 and 30 times 3 is 90 so 5 is your answer
Answer:
42
Step-by-step explanation:
b to the second power thats 1 plus 1 plus 5 times -1to the second power plus seven times 7 and 6 get you the answee 42
I believe the answer is 116.
23-8=15
8*15=120
sqrt2=4
the number 120-4=116
that’s what i got not sure if that is correct
Answer:a valid solution is (1,3)
Explanation:First, let' simplify the given equation:
14mn = 55 - 7m - 2n
14mn + 2n = 55 - 7m - 2n + 2n
n (14m + 2) = 55 - 7m
n =
Now, we have only one equation in two unknowns. Therefore, the only way to solve this is by assuming one of the variables and solving for the other taking into consideration that both should be positive integers.
1- Assume m = 2:
n =
.....> n is not a positive integer .........> This assumption is rejected
2- Assume m = 1:
n =
.......> both m and n are positive integers ........> This assumption is accepted ...........> Therefore, the solution would be (1,3)
Hope this helps :)
