Answer: Both answers equal 198

Step-by-step explanation:

While at first this problem may look weird and even stump you. However, break it up.

What is 273-75? 198

What is 280-82? 198

The reason both equation equals each other are because both have the same answer.

Another example problem: 100-1=26+73

100-1= 26+73

100-1 = 99

26+73 = 99

The answer is 198
273-75 = 198
280-82=198
so it’s 198=198

A. Complete the table if y varies

serious [3.7K]

Direct variation is represented by the equation y = k × x and inverse variation is represented by y = k/x

Table 1:

y = k × x

30 = k × 5

30 = 5k

k = 30/5

k = 6

So,

y = 30

y = 30 k = 6

y = 30 k = 6x = 5

y = 30 k = 6x = 5Equation: y = 6x

y = k × x

y = 10 × 8

y = 80

So,

y = 80

y = 80 k = 10

y = 80 k = 10x = 8

y = 80 k = 10x = 8Equation: y = 10x

y = 3x

18 = 3x

x = 18/3

x = 6

So,

y = 18

y = 18k = 3

y = 18k = 3x = 6

y = 18k = 3x = 6Equation: y = 3x

y = 2x²

72 = 2x²

x² = 72/2

x² = 36

x = √36

x = 6

So,

y = 72

y = 72k = 2

y = 72k = 2x = 6

y = 72k = 2x = 6Equation: y = 2x²

Table 2:

y = k/x

5 = k/6

5 × 6 = k

30 = k

So,

y = 5

y = 5k = 30

y = 5k = 30x = 6

y = 5k = 30x = 6Equation: y = 30/x

y = k/x

y = 36/4

y = 9

So,

y = 9

y = 9k = 36

y = 9k = 36x = 4

y = 9k = 36x = 4Equation: y = 36/x

y = 60/x

20 = 60/x

20x = 60

x = 60/20

x = 3

So,

y = 20

y = 20k = 60

y = 20k = 60x = 3

y = 20k = 60x = 3Equation: y = 60/x

y = 24/x

y = 24/12

y = 2

So,

y = 2

y = 2k = 24

y = 2k = 24x = 12

y = 2k = 24x = 12Equation: y = 24/x

Square root of 20 is it rational or irrational ?

olga55 [171]

Each square root of a number that does not generated as a square of an integer is irrational. This means that none of the given numbers is rational, that is, they are all irrational.

Good luck!!!!

Someone pls pls help

Answer:

y= 1/4,1/2,1,2,4,8,16,32,64

Step-by-step explanation:

Make negative powers positive by turning them into a fraction so $2^{-2}$ is really

$\frac{1}{2^{2} }$ = $\frac{1}{4}$ so $2^{-1}$ is just $\frac{1}{2}$ . then $2^{0}$ =1 [any number to the zero power is = 1],

2^1 = 2, 2^2=4, 2^3=8, 2^4=16, 2^5=32, 2^6 = 2x2x2x2x2x2=64
