A)the solution of the equation is x=-12
Step-by-step explanation:
Hello
let
to begin isolating we must multiply both sides by 3x + 7.

this way

let´s continue to find x

the solution of the equation is x=-12
have a great day
If the northern side has length x and the east and west sides have length y, then the cost of the fence is
<span>C = 12x + 12y + 6y </span>
<span>and the enclosed area is A = xy. </span>
<span>12x + 18y = 6000 </span>
<span>x = 500 - 1.5y </span>
<span>A = 500y - 1.5y^2 </span>
<span>A is maximized when y = 500/3. In which case x = 250. </span>
X^2+ (y+8)^2 = 81.....this is C.
X^2 + y^2 + 16y +64=81 so x^2 + y^2 + 16y = 17.....this is D.
So I’d say C and D are correct
Answer:
D. 13 * 19 - 13x
Step-by-step explanation:
To get your answer, you have to distribute 13 to both numbers inside the parenthesis. So it would be 13 * 19 - 13 * x. You don't need the multiplication sign between the 13 and the x to say that they need to be multiplied.
Hello!
This is a problem about probability.
What we would first do is find the theoretical probability that Susan would roll the number 3 on a die.
Assuming that this is a fair six sided die, there is only one face with the number 3, and there are 6 sides, meaning that the probability that Susan rolls a 3 would be
.
Now, Susan is rolling a die 1,086, meaning that we can divide this number by 6 to find the theoretical number of times that Susan would roll the number 3 on this die.
You should get 181 times, which would be a good estimate of how many times she could roll the number 3.
Hope this helps!
