2/9x+-2=6 <br> i need help anyone?

Diano4ka-milaya [45]

Answer:

x = 36

Step-by-step explanation:

We have the equation (2/9)x + -2 = 6.

First, notice that adding a negative number is the same as subtracting by that number. So:

(2/9)x + -2 = 6

(2/9)x - 2 = 6

Now, we need to isolate the variable. Add 2 to both sides to cancel out the -2 on the left:

(2/9)x -2 + 2 = 6 + 2

(2/9)x = 8

Now multiply both sides by 9/2 to cancel out the 2/9 on the left:

(9/2) * (2/9)x = 8 * (9/2)

x = 72/2 = 36

Thus, x = 36.

In a triangle the first angle is 10 degrees more than the second angle. The third angle is equal to the sum of first 2 angles .

timurjin [86]

First angle= x+10
Second angle = x
Third angle = x+x+10 or 2x+10

X+10+x+2x +10=180
4x+20=180
Subtract 20 from both sides
4x=160
Divide both sides by 4
X=40
First angle =50
Second angle=40
Third angle =90
