Bailey & Riley sell magazines.
Solnce55 [7]

Answer:

10

Step-by-step explanation:

We can write Bailey's equation as:

29 + 1.50x

and Riley's equation as:

20 + 2x

Where

x is the number of magazines sold

Since Riley sold 12, her total pay for that day would be:

20 + 2x

20 + 2(12)

20 + 24

$44

Now, how many magazines Bailey need to sell? We equate Bailey's equation to 44 and find x:

29 + 1.5x = 44

1.5x = 44 - 29

1.5x = 15

x = 15/1.5

x = 10

hence, Bailey need to sell 10 magazines to make same money as Riley

1. What is the solution to the system below?<br> x+y=5<br> 1x- y=3
Alika [10]

Answer:

(4,1)

Step-by-step explanation:

x+y=5

x- y=3

Add the equations together to eliminate y

x+y=5

x- y=3

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

2x = 8

Divide each side by 2

2x/2 = 8/2

x = 4

Now we can find y

x+y = 5

4+y = 5

Subtract 4 from each side

4+y-4 = 5-4

y =1

Simplify sin^2y/sec^2 y−1 to a single trigonometric function
liubo4ka [24]

Answer:

\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 }  =  { \cos }^{2} y

Step-by-step explanation:

We know that { \tan }^{2} y =  { \sec }^{2} y - 1

Also , { \tan}^{2} y =   \frac{ { \sin }^{2} y}{ { \cos }^{2}y }

So ,

\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 }  =  \frac{ { \sin}^{2} y}{ { \tan }^{2} y}  =  \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } }  =  { \cos }^{2} y
