Jacob paid $120, which is 80% of the original price, for an e-book reader.
What was the original price

Answers

Answer 1

Answer:

144$

Step-by-step explanation:

Do 120+20%, because you already have 80%, so you need to add the other 20%.

Hope this makes sense. If not, tell me and I will fix it for you.

Answer 2

Answer:

The original price was $150

Step-by-step explanation:

$120 and 80% symbolize eachother. There is 20% missing from 80% and $120. To find the 20%, divide 80% by four and divide 120 by four to get $30.

$30 is the 20% we were missing. then, we add those to the already existing numbers. $120+$30=$150 and 80%+20%=100%.

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.

ANSWER ASAP FOR BRAINLIEST

Answers

Step-by-step explanation:

Given : x³+y³+z³=k   ,  k from 1 to 100

To Find : x, y, and z

Solution:

This Question can have lot of solutions as constraints are very less

there is no information whether x , y & z are integer

+ ve  , Real   numbers  

k = 1

x= 1 , y = 0 , z = 0

x =0 , y = 1 , z = 0

x = 0 , y = 0 ,  = 1

k = 2

x= 1 , y = 1 , z = 0

x =0 , y = 1 , z = 1

x = 1 , y = 0 ,  = 1

k = 3

x= 1 , y = 1 , z = 3

x = 1 , y = 1 , z = 1

x = 1 , y = 0 ,  = 1

k = 4

x=∛3 , y = 1 , z = 0

x=∛2 , y = ∛2 , z = 0

x=∛2 , y = 1 , z = 1

This way we can have so many solution

Easiest :

x³+y³+z³=k,

x = ∛k  , y = 0 , z = 0  will satisfy

At the theater, the Seward family bought 2 adult tickets and 3 children's tickets for $44.50. The Sena family bought 3 adult tickets and 6 children's tickets for $78. Find the price of an adult ticket and the price of a child's ticket.

Answers

Answer:

Adult ticket is $7.5 while a child's ticket is $11

Step-by-step explanation:

Given data

Let the cost of an adult ticket be x

and the cost of a child ticket be y

The Seward family

2x+3y= 44.50---------1

The Sena family

3x+6y= 78-------------2

solve 1 and 2

2x+3y= 44.50   X2

3x+6y= 78        X1

   4x+6y= 89

- 3x+6y= 78

  x+ 0= 11

x= 11

put x= 11 in 1

2x+3y= 44.50

2*11+3y= 44.5

22+3y=44.5

3y= 44.5-22

3y= 22.5

y= 22.5/3

y= 7.5

Hence Adult ticket is $7.5 while a child's ticket is $11

Solve the system using elimination

2x+3y=8
5x+6y=17

Answers

Answer:

x=1

Step-by-step explanation:

For this problem, we can choose to eliminate either the x values or the y values.

In this case, it would be easier to do y.

We alter the first equation by multiplying by -2 on both sides.

-4x+-6y=-16

Now, we have the equations

-4x+-6y=-16 and 5x+6y=17.

We can see that there is -6y in one equation and 6y in the other, meaning that if we add both equations together, the ys will cancel each other out because they are opposites.

So let's add the equations.

-4x-6y+5x+6y=-16+17

x=1
