Step-by-step explanation:
Since it takes b minutes to fill one bathtub, then it will take 3 times b minutes to fill all three bathtubs.
Answer:
i think
Step-by-step explanation:
4 or 1
Part A:
If (7^2)^x = 1 then the value of x is equal 0
Because when x = 0 the
(7^2)^0 = 1 ; 7^0 = 1
Any number with 0 exponent is always equal 0, except 0.
Part B:
If (7^0)^x = 1, then the value of x is all real number
Because when 0 multiplies any number, it is always equal 0. So then 7^0 is always equal 1.
Example
if x = 1 then (7^0)^1 = 7^0 = 1
if x = -1 then (7^0)^(-1) = 7^0 = 1
if x = 1000 then (7^0)^(1000) = 7^0 = 1
Answer:
Problem 2: k = 3
Problem 4: NO SOLUTION
Step-by-step explanation:
Problem 2 work:
-4/3(12k + 27) = -57 - 9k
-16k - 36 = -57 - 9k -ADD THE -9k TO ITSELF AND TO -16k-
-7k - 36 = -57 -ADD THE -36 TO ITSELF AND -57-
-7k = -21
<u><em>k = 3</em></u>
<u><em /></u>
Problem 4 work:
5/2(6w - 16) = 18w -(3w + 40)
15w - 40 = 18w - 3w - 40 -ADD THE -3w TO THE 18w-
15w - 40 = 15w - 40
NO SOLUTION BECAUSE BOTH SIDES ARE THE SAME
