Mathematics

Tatiana [17]3 years ago
8 0

Answer:     " 1 lb ,  14 oz. " .

_________________________________________________

Step-by-step explanation:

_________________________________________________

Note the exact conversion:    " 16 oz.  =   1 lb.  " .

→  {that is:  " 16 ounces  =  1 pound " .}.

_________________________________________________

  30 oz. * ( 1 lb / 16 oz). =  \frac{30}{16}  lbs. ;

                                      = (30/2) / (16/2)   lbs.

                                      =  (15 / 8) lbs.  ;

_________________________________________________

       1

8 ┌ 15

 <u>   -  8   </u>                          

        7  ;              

______________________

The answer is equal to:  " 1  7/8  lbs. " .  

           →   (1 lb)  + (7/8) (lb).  ;

______________________

 →  (7/8) lb.   =  how many "oz." ??

_______________________

Note the exact conversion:   " 1 lb.   =   16 oz.  " .

_______________________

 →   \frac{7 lb}{8} * \frac{16 oz}{1 lb}  ;

                    =  \frac{7}{8} * \frac{16}{1}  oz.   ;

 →  The "8" cancels to a "1" ; and the "16" cancels to a "2" ;

                   →  {since:  " {16 ÷ 8 = 2 } " ;  

             and:   {since:  " {8 ÷ 8 = 1 } " .

_______________________________________________

 →  So we can rewrite as:  

_______________________________________________                  

                  →  \frac{7}{1} *  \frac{2}{1}  oz. ;

                         =  { 7  *  2 }  oz.  ;

                         =   14  oz.

_______________________________________________

→  So:        

_______________________________________________  

 →   " 30 oz. "  =  " (1 lb)  + (7/8) lb.  "  ;

                        =  "  1 lb. + 14 oz. "  ;

                        =  " 1 lb ,  14 oz. " .

_______________________________________________

        →  The answer is:  " 1 lb ,  14 oz. " .

_______________________________________________

Let us check our answer:

  →   Does:     " 1 lb.  +   14 oz. = ?  30 oz. ? " ;

_______________________________________________

Note the exact conversion:  " 1 lb.  =  16 oz. " .

_______________________________________________

  →   Does:  " 16 oz.   +   14 oz.   =  ?   30 oz. ??  " ;

_______________________________________________

  ₁

  16 oz            

<u>+ 14 oz        </u>    

  30  oz.

_______________________________________________

→   Does:   " 30 oz.  = ?  30 oz. ? "  ??? ;  →   Yes!

_______________________________________________

Hope this helps!

 Best wishes to you in your academic endeavors

Solve using elimination 5x+7y=9 <br> 2x-3y=-37
uranmaximum [27]

Answer:

x = -8

y = 7

Step-by-step explanation:

5x + 7y = 9

2x - 3y = -37

1.) First, multiply each side to match either y-values or x-values. (In this example, we'll use match x-values)

10x + 14y = 18 (multiplied by 2)

10x - 15y = -185 (multiplied by 5)

2.) Then, subtract the entirety of one equation to isolate the y-value.

10x + 14y = 18

-10x + 15y = 185

3.) Add and subtract values and divide to find y.

29y = 203

y = 7

4.) Plug-in y to solve for x into one equation, or repeat steps 1-3.

15x + 21y = 27

14x - 21y = -259

29x = -232

x = -8

5. Sean has 56 bills in his pockets. The bills are only fives and tens.
noname [10]

Answer:

He have 43 bills of 10 and 13 bills of 5

Step-by-step explanation:

5x + 10y = 495

x + y = 56

Isolate x:

x = 56 - y

Substitute in the first equation:

5(56 - y) +10y = 495

280 -5y +10 y = 495

5y = 495 -280

5y = 215

y = 215/5

y= 43

Now substitute the value of y to find x:

x = 56 - y

x = 56 - 43

x = 13

There are (4^2)^3 ⋅ 40 horses on a stud farm. What is the total number of horses on the farm?
Colt1911 [192]

If this is for real, the answer is 163,840 horses on the farm, because 4^2 is 16, and 16^3 is 4,096, and 4,096 times 40 is 163,840.
