Answer:

-3/5

Step-by-step explanation:

first of all, let's just deal with the negative so it doesn't mess us up at the final answer. Pos×neg×neg×neg is going to be neg (an odd number of negatives will be negative).

If you know how to cancel, you can do that and make your life easier. But cancelling is REALLY just dividing. Generally, you can multiply fractions by multiplying all the top numbers together and put that on top. And multiply all bottom numbers together and put that on the bottom. But then you have to simplify. See image.

Which inequality best represents that ice cream at −5°C is cooler than ice cream at 4°C?

konstantin123 [22]

(<) this means less than
(>) this means greater than
So since the question doesnt say anything about -4°C we can automatically cross out A and B
They are both negative! but when you have a negative. Its going to be less than a positive
So this means 4°C is greater than -5°C
or in other words
D.) 4°C > -5°C
hope this helps!

The school that Joe goes to is selling tickets to a choral performance. On血e first day of ticket

ArbitrLikvidat [17]

Answer:

The price of one senior citizen ticket is $8, and the price of one child ticket is $11.

Step-by-step explanation:

You are looking for two things: the price of a senior citizen ticket and the price of a child ticket.

We need to write two equations using two variables.

Let s = price of 1 senior citizen ticket.

Let c = price of 1 child ticket.

First day of ticket sales:

6 senior citizen tickets, 8 child tickets, total sales of $136

Since s is the price of a senior citizen ticket, 6 tickets cost 6s.

Since c is the price of a child ticket, 8 tickets cost 8c.

The total sales is 6s + 8c.

The total sales is $136, so our first equation is

6s + 8c = 136

Now we do the same for the second day of ticket sales.

6 senior citizen tickets, 9 child tickets, total sales of $147.

Since s is the price of a senior citizen ticket, 6 tickets cost 6s.

Since c is the price of a child ticket, 9 tickets cost 9c.

The total sales is 6s + 9c.

The total sales is $147, so our second equation is

6s + 9c = 147

The system of equations is

6s + 8c = 136

6s + 9c = 147

Multiply both sides of the first equation by -1. Write the second equation below it. Then add the equations.

-6s - 8c = -136

(+) 6s + 9c = 147

----------------------------

c = 11

c = 11, so the cost of a child ticket is $11.

Now substitute 11 for c in the first equation, and solve for s.

6s + 8c = 136

6s + 8(11) = 136

6s + 88 = 136

6s = 48

s = 8

The price of a senior citizen ticket is $8.

The price of a senior citizen ticket is $8, and the price of a child ticket is $11.

What is the surface area?????

Elenna [48]

The area of a triangle is found using the formula Area = 1/2 x base x height.

Base = 8

Height = 18.

The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.

There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2
