Tahnks for helping it will mean a lot
VMariaS [17]

Answer:

- 1.2  , - \frac{1}{2} ,0.44,\frac{7}{3}

Step-by-step explanation:

We want to arrange the following numbers on the number line in order from least to greatest.

The numbers are:

0.44, \frac{7}{3} , - 1.2, -  \frac{1}{ 2}

Let us convert everything into decimals to get:

0.44,2. \bar3 , - 1.2, - 0.5

Rearranging from least to greatest, we have:

- 1.2  , - 0.5 ,0.44,2. \bar3

The school that Imani goes to is selling tickets to the annual dance competition. On the first day of the ticket sales the schoo
Tatiana [17]

Answer:

The adult and the child ticket are both 8 dollars

Step-by-step explanation:

x =adult ticket price

y = child ticket price

I will assume you forget to put that they sold 2 child tickets on the second day

7x+5y=96 and 3x+2y= 40

I will use elimination.  Multiply the first equation by 2 and the second equation by -5 to eliminate y

2(7x+5y)=96*2

14x + 10y = 192

The second equation

-5(3x+2y)= 40*-5

-15x -10y = -200

Add the equations together

14x + 10y = 192

-15x -10y = -200

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

-x = -8

Multiply by -1

x = 8

Now we need to find y

3x+2y= 40

3(8) +2y = 40

24+2y = 40

Subtract 24 from each side

24-24 +2y = 40-24

2y = 16

Divide by 2

2y/2 =16/2

y =8

The adult and the child ticket are both 8 dollars
