Paul [167]

Answer:

A. (4,2)

Step-by-step explanation:

In coordinates, the x-value appears first then the y-value. This means coordinates are set up like, (x,y). So, to solve find the coordinates whose values match one pair of values on the table.

Tresset [83]

Answer:

10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Step-by-step explanation:

To find : How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?

Solution :

The place value stem is

Thousand     Hundred     Tens    Ones

  1000               100            10         1

The value of 5 in 3,590 is at hundred place

So, 5\times 100=500

The value of 5 in 359 is at tens place

So, 5\times 10=50

Number of time greater is the value of 5 in 3,590 than the value of 5 in 359 is given by,

n=\frac{500}{50}

n=10

Therefore, 10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Help me plz The formula K=59(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.
quester [9]

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

k = 59(f - 32) + 273.15

Subtract the sides of the equation minus -273.15

k - 273.15 = 59(f - 32)

Divided the sides of the equation by 59

\frac{k - 273.15}{59} = \frac{59}{59}  (f - 32)  \\

\frac{k - 273.15}{59} = f - 32 \\

Subtract the sides of the equation plus 32

\frac{k - 273.15}{59} + 32 = f \\

And we're done.

Thanks for watching buddy good luck.
