Nine times a number is one more than ten times the number.

Mathematics

slava [35]3 years ago

I will rewrite the wording and write out the equation as it goes so there is better understanding. Once I do that, I will solve it for you.
Nine times a number (9n) is (=) one more than ten times the number (10n + 1).
Now that we've rewritten it, let's only write what we have in parenthesis.
9n = 10n + 1.
Now that we have our equation, let's solve!
9n = 10n + 1
Subtract 10n from both sides.
-1n = 1
Divide both sides by -1.
n = -1
I hope this helps!

HELP What is the area of this figure?
Mademuasel [1]
The correct answer is:  [B]:  "40 yd² " .
_____________________________________________________
First, find the area of the triangle:

The formula of the area of a triangle, "A":

A = (1/2) * b * h ; 

in which:  " A = area (in units 'squared') ;  in our case, " yd² " ; 

                 " b = base length" = 6 yd.  

                 " h = perpendicular height" = "(4 yd + 4 yd)" = 8 yd.
___________________________________________________
→  A = (1/2) * b * h = (1/2) * (6 yd) * (8 yd) = (1/2) * (6) * (8) * (yd²) ; 
                                                                 
                                                                   =  " 24 yd² " .
___________________________________________________
Now, find the area, "A", of the square:

The formula for the area, "A" of a square:

   A = s² ;

in which:  "A = area (in "units squared") ; in our case, " yd² " ;
                 
                 "s = side length (since a 'square' has all FOUR (4) equal side lengths);

 A = s²  = (4 yd)² = 4² * yd² =  "16 yd² "
_________________________________________________
Now, we add the areas of BOTH the triangle AND the square:
_________________________________________________
        →  " 24 yd²  +  16 yd² " ; 

to get:  " 40 yd² " ;  which is:  Answer choice:  [B]:  " 40 yd² " .

ALL MY QUESTIONS GETTING IGNORED PLS HELP
Novosadov [1.4K]

Answer:

x=9

Step-by-step explanation:

a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.

15/5 = 3

12/4 = 3

therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.

3*3=9

x=9
