Answer:
7
Step-by-step explanation:
First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3
Which gives you 2/3 (9x - 6)
Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3
then you divide 6/3 with 2
Getting 2 (3x - 2)
The use the distributive law
2 x 3x - 2 x 2
simplify the equation
6x - 4
expand 4 (x +2) + 2: 4x + 10
which then equals 6x-4=4x+10
add 4 to both sides
6x-4+4=4x+10+4
simplify
6x=4x+14
subtract 4x from both sides
simplify again
2x=14
divide both sides by 2
2x/2 = 14/2
simplify one last time and get the answer
x=7
If you equate both, the y is eliminated:
-6x-3 = -x+2
Simplify this to find x:
-5x = 5
x = -1
Fill in x=-1 in either equation:
y = --1 + 2 = 3
So (-1,3) is the solution, it is where the lines intercept.
To simplify this, we first need to distribute the 2 into the parenthesis.
= 2 * x + 2 * 3 - 4
Now, we can simplify:
= 2x + 6 - 4
= 2x + 2
Hope this helps!
Answer:
52
Step-by-step explanation:
A(2) + B(2) = C(2)
10(2) + 24(2)
676 = C(2)
square root of 676
AC=26 BD=26
AC + BD
26 + 26 =
52
Hope this helps
You write a proportion 576/8=x/2. And solve for x. x=144.
