Step-by-step explanation:
Let's say the two digit number is 10x + y, where x is the first digit and y is the second digit.
The sum of the digits is 8:
x + y = 8
If 8 is subtracted from the number, the digits switch place.
10x + y − 8 = 10y + x
Simplify the second equation:
9x − 8 = 9y
Substitute from the first equation.
y = 8 − x
9x − 8 = 9 (8 − x)
9x − 8 = 72 − 9x
18x = 80
x = 4.444
There's a problem. x isn't an integer. Are you sure you copied the problem correctly? Perhaps you meant if 18 is subtracted from the number, the digits switch place.
9x − 18 = 9 (8 − x)
9x − 18 = 72 − 9x
18x = 90
x = 5
y = 8 − x
y = 3
So the number is 53.
Answer:
f(3/2)= 5√5
Step-by-step explanation:
f(3/2)= 5^(3/2)
f(3/2)= (5^3)^1/2 is the same things
f(3/2)= (125)^1/2 fraction exponent are the same are roots ^(1/2) is √
f(3/2)= √125
f(3/2)= √25 times √5 break up 125 to be 25 x 5
f(3/2)= 5√5 because √25 = 5 and √5 stays as √5
Answer:
i think it is c because its a complete question and sentence if im wrong tell me ( ;
brainlyest would be nice btw ( ;
Step-by-step explanation:
The answer is Division property of equality. This is because at Step 3, you have to divide to get your final answer. It cannot be the other ones because you do not subtract or distribute in step 3.
The square root of 75/3 is a irrational number
