It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
Logic.
Answer:
Step-by-step explanation:
Not exactly sure what your question is - I am assuming that it is something like:
Show/prove that for any integer x, x^2 - x is even.
Suppose that x is an even integer. The product of an even integer and any other integer is always even (x = 2n, so x * y = 2 n * y which is even. Therefore x^2 is even. An even minus an even is even. (The definition of an even number is that it is divisible by 2 or has a factor of 2. So the difference of even numbers could be written as 2*( the difference of the two numbers divided by 2); therefore the difference is even)
Suppose that x is an odd integer. The product of 2 odd numbers is odd - each odd number can be written as the sum of an even number and 1; multiplying the even parts with each other and 1 will produce even; multiplying the 1's will produce 1, so the product can be written as the sum of an even number and 1 - which is an odd number. The difference between two odd numbers is even - the difference between the even parts is even (argument above), the difference between 1 and 1 is zero, so the result of the difference is even.
x^2 is therefore even if x is even and odd if x is odd; The difference x^2 - x is even by the arguments above.
Answer:
158.11
Step-by-step explanation:
Let's solve your equation step-by-step.
24(log(2x))=60
Step 1: Divide both sides by 24.
24(log(2x))
/24
=
60
/24
log(2x)=
5
/2
Step 2: Solve Logarithm.
log(2x)=
5
/2
10log(2x)=10
5
/2
(Take exponent of both sides)
2x=10
5
/2
2x=316.227766
2x
/2
=
316.227766
/2
(Divide both sides by 2)
x=158.113883
Answer:
x=158.113883
Answer:
Step-by-step explanation:
3x - 2 + x + 8 = ( 9x + 7 - x + 5)/2
Add the like terms
4x + 6 = 8x + 12/2
Cross multiply or multiply both side by two
2(4x + 6) = 8x + 12
Use 2 to open the bracket
8x + 12 = 8x + 12
Collect like terms
8x - 8x = 12 - 12
0 = 0
Therefore, the equation has no solution
