mj thinks of a number. she adds 2 to the number then multiples the result by 3. The answer is the same as adding 5 to the number them multiplying by 2
my number is d
3 (d×2) = 2 (d+5)
3×d + 3×2 = 2×d + 2×5
3d + 6 = 2d + 10
3d +6 -6 -2d = 2d - 10 - 6
3d - 2d = 10 - 6
d = 4
Answer:
The algebraic expression of "two more than the quotient of six and a number, n is 2 + 6/n
Step-by-step explanation:
The quotient number of six and a number n = 6 / n
two more than the quotient of six and a number, n = 2 + 6/n
The algebraic expression of "two more than the quotient of six and a number, n is 2 + 6/n
The correct answer for this question is this one: "C).a unique,acute triangle"
The statement that best describes a triangle with side lengths of 6 inches 8 inches and 9 inches is that it is <u>a unique,acute triangle</u><span>
Hope this helps answer your question and have a nice day ahead.

Answer:
step two added the 9 to each side :)
-10y + 9x = - 9....A
10y + 5x = - 5.....B
You should see right away that -10y and 10y cancel out.
We are left with
14x = -14
x = -14/14
x = -1
Plug x = -1 into EITHER equation A or B to find y.
I will use equation A.
-10y + 9(-1) = - 9
-10y - 9 = - 9
-10y = - 9 + 9
- 10y = 0
y = 0/-10
y = 0
Done!
