At the city museum, child admission is $5.40 and adult admission is $8.70 . On Friday, 170 tickets were sold for a total sales of $1224.90 . How many adult tickets were sold that day?

Answers

Answer 1

Answer: x=number of adult tickets
y=number of children tickets.
we can suggest this system of equations:

x+y=170
8.7x+5.4y=1224.90

We can solve this system of equations by substitution method:
x=170-y

8.7(170 - y)+5.4 y=1224.90
1479-8.7y+5.4y=1224.90
-3.3 y=1224.90-1479
-3.3 y=-254.1
y=(-254.1) /(-3.3)
y=77

x=170-y
x=170-77
x=93

Answer:93 adult tickts were sold that day.

You have a coupon good for $5 off the price of any large pizza. You also get a 15% discount on any pizza if you show your student ID. How much more would you pay for a large pizza if the cashier applies the coupon first?

Answers

Below is the solution for the problem above:

Given:
Let x be the price of the pizza
$5 for the coupon
15% discount

Solution
x is the price of the pizza. If coupon is applied before:
(x-5)0.85=0.85x-0.85*5

if it is applied after: 0.85x-5

Therefore, the difference between the two is 0.15*5=0.75

The answer is USD 0.75

Simplify 3j - {2k - [5h - (3j + k)]}.-3h - 5k
3h - 5k
5h - 3k
-5h - 3k

Answers

If you would like to simplify 3j - {2k - [5h - (3j + k)]}, you can do this using the following steps:

3j - {2k - [5h - (3j + k)]} = 3j - {2k - [5h - 3j - k]} = 3j - {2k - 5h + 3j + k} = 3j - 2k + 5h - 3j - k = - 3k + 5h = 5h - 3k

The correct result would be 5h - 3k.

Answer:

to simplify 3j - {2k - [5h - (3j + k)]}, you can do this using the following steps:

3j - {2k - [5h - (3j + k)]} = 3j - {2k - [5h - 3j - k]} = 3j - {2k - 5h + 3j + k} = 3j - 2k + 5h - 3j - k = - 3k + 5h = 5h - 3k

The the answer is 5h - 3k.

What is the median of 37, 39,40, 42,42, 45, 48, 49, 51, 52?

Answers

To find a median, first order the numbers from least to greatest, or vice versa.
Then, the middle number in that sorted list is the median.

But, this list is already sorted.
So, the median is 42 & 45.

Technically, the answer is 42 & 45.

The middle of 42 & 45, however, is 43.5

Hope this helped!

The median is ...........
43.5

2(3x+4y)=4x+12y
solve

Answers

6x + 8y = 4x + 12y
6x - 4x = 12y - 8y
2x = 4y
x = 2y

is it x=2y?
Because 6x+8y=4x+12y
=>2x+8y=12y
and 2x=4y, so x=2y
