Answer:

5 sessions each

Step-by-step explanation:

Let the personal training sessions be x.

Then at Silver Gym Sarah would spend:

35 + 30x

And at Fit Factor she would spend:

85 + 20x

Since total costs are same, the amounts will be equal:

35+30x = 85 + 20x
30x - 20x = 85 - 35
10 x = 50
x= 50/10
x= 5

So Sarah would buy 5 training sessions for each of the gyms.

And she would spend $185 at each.

((2x^9)(y^n))((4x^2)(y^10))=(8x^11)(y^20)

tino4ka555 [31]

We are given

$((2x^9)(y^n))((4x^2)(y^{10}))=(8x^{11})(y^{20})$

Firstly, we simplify left side

Left side is

$((2x^9)(y^n))((4x^2)(y^{10}))$

we will make all x terms together

and y terms together

$(2x^9)(4x^2)(y^n)(y^{10})$

$2\times 4(x^9)(x^2)(y^n)(y^{10})$

$8(x^9)(x^2)(y^n)(y^{10})$

we can multiply left side by using exponent rule

$a^m\times a^n=a^{m+n}$

$8(x^{9+2})(y^{n+10})$

$8(x^{11})(y^{n+10})$

now, we can set them equal

$(8x^{11})(y^{n+10})=(8x^{11})(y^{20})$

Since, both sides have x,y and 8

and both are equal

so, their exponent must be equal

so, exponent of y must also be equal

we get

$n+10=20$

Find two numbers between 1.4142133 and 1.41422

Naddik [55]

Hey there! I'm happy to help!

To find the number halfway between two numbers, you simply add them and then divide by two.

1.4142133+1.41422=2.8284333

2.8284333/2=1.41421665

That is one number in between these two. Now, we can find the number in between the middle number and the second number. This is another number in between our two numbers.

(1.41421665+1.41422)/2=1.414218325

You could keep on doing this and find tons of numbers in between these two.

Therefore, two numbers between 1.4142133 and 1.41422 are 1.41421665 and 1.414218325.

Have a wonderful day! :D

Answer:

Step-by-step explanation:

Since we know QR and RS are the same, we can add them together

6 + 6 = 12

Since the whole line is 15 we subtract 12 from 15

15 - 12 = 3
