Answer:
They bought 23 tickets for children and 52 for adults.
Step-by-step explanation:
So first you must find what i represents so here it is
A= Adult
C= Children
They both sold the tickets which is going to be
A + C = 75
Now here it shows
12= each adult ticket
8= each children ticket
find the equation like this 12 A + 8C = 808
Now to find the C
You can find by resolving it like this
C= 75 - A
Solve the A and C
4A = 208
A = 52
12 (52) + 8C = 808
624 + 8C = 808
Children = 23
Adult= 52
Just set them equal to each other
2x-2= x+3
2x-5=x
-5= -x
X=5
Hope it helps
Answer:
3*sqrt(3x)
--------------
2x
Step-by-step explanation:
To rationalize the denominator, we need to get rid of the square root. We need to multiply by sqrt(12x)/sqrt(12x)
9 sqrt(12x)
---------- * -----------
sqrt(12x) sqrt(12x)
9sqrt(12x)
-----------------
12x
We can cancel 3 in the top and bottom
3sqrt(12x)
---------------
4x
We also notice that 12 is made up of 4 and 3
3sqrt(4) sqrt(3x)
---------------
4x
3sqrt(4) sqrt(3x)
----------------------
4x
3*2sqrt(3x)
--------------
4x
We can cancel a 2 in the top and bottom
3*sqrt(3x)
--------------
2x
Yes, it is a doubles fact because it has idk...
Answer: 2/5
Step-by-step explanation: Using the place value chart, we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4/10.
Notice however that 4/10 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2.
So if we divide the numerator and the denominator by 2, we get the equivalent fraction 2/5.
Therefore, 0.4 can be written as the fraction 2/5 which is in lowest terms.
