I assume this is

[3 *45] / [ 16 + 5]  =

(3/21) * 45 

(1/7) * 45  =

45/7

I don't quite understand what you want. If you want the power of 10 that will give you 58,000,000,000, then that is very easy:

10^x=58,000,000,000, we take the logs of both sides,

xLog(10)=Log(58,000,000,000)

x=10.763428....I hope that's what you want.

it is easy dumm a*s use a caulalator

             2x - 5

             2x - 5

         -------------

          -10x + 25

4x^2  -10x

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

4x^2  - 20x  + 25

4 - (-6)  =    4 + 6 = 10

Note that this limit only exists from the right.....

lim x -> 0⁺ x-sqrt(x) / x + sqrt(X)   multiply both by  x - sqrt x  on top and bottom

lim x -> 0⁺ [x^2 - 2xsqrt(x) + x] / [x^2 -x]   factor x out of top/bottom

lim x -> 0⁺ [x - 2sqrt(x)  + 1] / [x - 1]      let the limit go to 0

=  -1

Your answer is:

x = 15/4

2.38656•1000000

(9/25)x=(5/3)x^-2  multiply both sides by x^2

(9/25) x^3 = (5/3)      multiply both sides by 25/9

x^3 = (5/3)(25/9)  

x^3 = 125/27    take the cube root of both sides

x = 5/3

22 is the answer

(3•45)/16+5

=13.4375

This is a actual question i have the Same problem

Here's the equations and graphs for the rest of these:

14.    y = 35 + .10k     the amounts are in thousands  ..........https://www.desmos.com/calculator/w8kb2pds5q    . y= salesperson's income

15.  y = 30 +.15t     .......     https://www.desmos.com/calculator/14ndpgvn1j      y = total cellphone cost

16.  y = 25 - .5x    .....again, the amounts are in thousands......  https://www.desmos.com/calculator/ocoazmqoqv     y = total in bank account

17.  y = 350 + 150m ........https://www.desmos.com/calculator/bkbqzhlgiu   y = total in svings acct

18. y = 260 - 4m .........    https://www.desmos.com/calculator/9aodmmrfua     y = weight after m months

19.  y = 5 + 1.5d  .......   https://www.desmos.com/calculator/bzqcsj37qi    y = plant height

20.  y =  40000 + 300x  .........  https://www.desmos.com/calculator/43gpptaiaf    y = income

Solve for x over the real numbers:
(9 x)/25 = 5/(3 x^2)
Rewrite the right hand side of the equation.
5/(3 x^2) = 5/(3 x^2):
(9 x)/25 = 5/(3 x^2)
Multiply both sides by a polynomial to clear fractions.
Cross multiply:
27 x^3 = 125
Divide both sides by a constant to simplify the equation.
Divide both sides by 27:
x^3 = 125/27
Elminate the power on the left hand side.
Take cube roots of both sides:
Answer: 
x = 5/3

How you know what x is by omg i forgot

One way to remember when multiplying or dividing two numbers is that like signs give a positive result whereas unlike signs give a negative result....hope it helps

The rest of these pretty much follow along the lines of 12

13.) Julia has been measuring the length of her baby’s hair. The first time it was 6 cm long and after one 

month it was 2 cm longer. 

a. If the hair continues to grow at this rate, determine the function that represents the hair growth.

b. Graph the equation.

Let y be the length after time t  and we have

y = 2t  + 6

at t = 0, y = 6

at t = 1, y = 8

etc.

12.) Bobby fills a water tank at the rate of 0.12 mL in every minute. The tank had 1.08 mL before he

started filling the tank.

a. Determine the equation that represents the function.

b Graph the equation.

Note that the starting value is  1.08 ml

And every minute the tank increases by .12  ml

So......after one minute we have     .12(1)  + 1.08  = 1.2 ml

And after two minutes, we have   .12(2)  + 1.08  =  1.32 ml

etc.

So....let the height at some time = y

And the equation that models this is:

y = .12(t) + 1.08      where t is the time in minutes

Here's the graph.......https://www.desmos.com/calculator/gjtaxm5ow3

Haley.....hold down your mouse value and see the values at various times for t

At t =  0    y = 1.08

At t = 1   y = 1.20

its 5 if u r wrong...

its 6 if u r wrong...

its 8 if u r wrong..

yes

No....this isn't true

sqrt(2)  + sqrt (3) =  3.146

But

sqrt(2 + 3)   = sqrt(5)=  2.236

29 degrees 30 min  = 29.5°

sin(29.5°) = about . 492
