4x + 7x - 2 + 5x - 10 find the value of x

Mathematics

Answer:

x = 4/5

Step-by-step explanation:

1) Group like terms

   4x + 7x + 5x - 2 - 10 = x

2) Add similar elements

   16x - 2 - 10 = x

3) Subtract

   16x - 12 = x

4) Add 12 to both sides

   16x - 12 + 12 = x + 12

5) Simplify

   16x = x + 12

6) Subtract x from both sides

   16x - x = x + 12 - x

7) Simplify

   15x = 12

8) Divide both sides by 15

    15x/15 = 12/15

9) Simplify

   x = 4/5

Points F,G, and H are collinear such that FG:FH=2/3.If a directed line segment begins at F(-3,2) and ends at H (-3,7), find the
Nana76 [90]
We consider the x- and y-coordinates separately. Let the coordinates of G be (x, y). Now considering the x-coordinates:
FG/FH = (x - (-3)) / (-3 - (-3)) = 2/3
x + 3 = (2/3)(6)
x = 1
For the y-coordinates:
FG/FH = (y - 2) / (7 - 2) = 2/3
y - 2 = (2/3)(5)
y = 16/3
Therefore the coordinates of G are (1, 16/3).

Suppose you invest $500 at an annual interest rate of 8.2% compounded continuously. How much will you have in the account after
Marianna [84]
Here is the formula that your going to need to use A=P(1+r/n)^nt
  So P=500, R=0.082, N=1, T=15
 Plug it into your equation and you have A=500(1+0.082/1)^(1)(15)
 Simplify what's in the parenthesis A=500(1.082)^(1)(15)
 Multiply your exponents A=500(1.082)^15 Then A=500(3.26)
 Finally you multiply your last two numbers to get A=1,630
 So after 15 years you would have $1,630
I hope this helped you :)
