A stadium's normal ticket price is $78. As a special promotion they offer 15% off. What is the price of the discounted ticket?

meriva

You have to find out what 15% of $78 dollars is. If you have to do this in your head and not on a calculator you can find 10%, then cut that number in 1/2 and add it to the answer. So 10% of $78 is 7.8 so $7.80. You can divide 7.80 by 2 and get 3.9 and add that to 7.8 which is 11.70. So 15% of $78 is $11.70.

Answer: True, False, False, False, False

Step-by-step explanation:

a) 5x - 7(x - 1)

5x - 7x + 7

-2x + 7 ⇒ a = -2, b = 7 One Solution

b) 3(x - 5) - 7

3x - 15 - 7

3x - 22 ⇒ a = 3, b = -22 One Solution

c) 2 - 7x + 3 + 4x

4x - 7x + 3 + 2

-3x + 5 ⇒ a = -3, b = 5 One Solution

d) -3(x - 3) - 1

-3x + 9 - 1

-3x + 8 ⇒ a = -3, b = 8 One Solution

e) -5x + 2 + 2x + 4

-5x + 2x + 2 + 4

-3x + 6 ⇒ a = -3, b = 6 One Solution

Mike has 21 pounds of tomatoes and 9 pounds of mixed peppers from his garden that he will use to make sals.

Grace [21]

The number of batches of salsa that can be made = x = 6 batches

The number of bat tomato sauce that can be made = y = 3 batches

Step-by-step explanation:

We are given the system of equations:

$x+5y=21\\x+y=9$

where variable x represents the number of batches of salsa that can be made and y represents the number of bat tomato sauce that can be made.

We need to solve the systems to find the values of x and y.

Let:

$x+5y=21\,\,\,eq(1)\\x+y=9\,\,\,eq(2)$

Subtract both equations:

$x+5y=21\\x+y=9\\-\,\,\,-\,\,\,\,\,\,-\\------\\4y=12\\y=\frac{12}{4}\\y=3$

So, value of y=3

Putting value of y in eq(2) and finding value of x:

$x+y=9\\x+3=9\\x=9-3\\x=6$

So, value of x=6

The number of batches of salsa that can be made = x = 6 batches

The number of bat tomato sauce that can be made = y = 3 batches
