Answer:
adult tickets are $8 and student tickets are $14
Step-by-step explanation:
to find the price of adult and student tickets, first look at all the given values:
a = adult tickets
s = student tickets
so: 4a + 5s = 102
and : 7a + 5s = 126
since in both equations the number of student tickets are the same, we have to find the difference of value to determine how much adult tickets are:
126-102 = 24
there are 3 more adult tickets in the equation with a total of 126, therefore:
24 / 3 = 8
that means each adult ticket is work 8 dollars.
now substitute this value:
4(8) + 5s = 102
32 + 5s = 102
you can solve this by concluding that 102- 32 is 70
that means 5(s) has to equal 70
so 70 / 5 = s
70/5 = 14
so the value of s = 14 and the value of a = 8
Answer:
x=-5 or -5
Step-by-step explanation:
x - 4 = 2x + 1
Subtract x from both sides canceling out the x on the left, getting...
-4 = x + 1
Then subtract the 1 from both sides canceling out the 1 on the right, getting...
-5 = x
Subtracting x from 2x gets you 1x which you just write as x because there is only one x. Doing the equation from the other side will still get you the same answer and I will show you.
x - 4 = 2x + 1
-x - 4 = 1
-x = 5
x = -5
Hope this helps!
Answer:
1,436 with a remainder of 4
Step-by-step explanation:
The first step is to see how many times 6 goes into 8
It goes in 1 time so you write 1 at the top and subtract 6 from 8
This gives you 2, and then you bring down the 6 from the 8,620
Now you have 26, and you see how many times 6 goes into 26
It goes in 4 times giving you 24 so you write 4 at the top
Then you subtract 24 from 26 giving you 2 and you drop down the 2
This gives you 22 and 6 goes into 22 3 times giving you 18
So you write 3 at the top and subtract 18 from 22 giving you 4
then you drop down the 0 from the 8,620 giving you 40
Then you evaluate how many times 6 goes into 40, it goes in 6 times
this gives you 36 and then you writes a 6 at the top and subtract 40 and 36
this gives you a remainder of 4

Answer:
let jolene's dvd be x
2x+x+3x= total dvds = 6x
2x/6x=1/3
Salena has 1/3 of the total dvds
