Answer: x = 5

Step-by-step explanation:

Here we want to solve the equation:

-2(x + 6) + 3 = -11x + 4(x + 4)

the first step is distribute the parentheses at both sides:

-2x -12 + 3 = -11x + 4x + 16

-2x - 9 = -7x + 16

now, we put all the termx with an x in one side, and the other ones in the other side.

-2x + 7x = 16 + 9

5x = 25

now we divide by 5 in both sides, in this way we can isolate x.

5x/5 = 25/5

x = 5

Answer:

x = 5

Step-by-step explanation:

We are given a linear single variable equation of x and we have to get the value of x from the equation.

Now, the equation is

- 2 ( x + 6 ) + 3 = - 11x + 4 ( x + 4 )

⇒ - 2x - 12 + 3 = - 11x + 4x + 16

⇒ 5x = 25

⇒ x = 5 (Answer)

Answer:

x = 5.85641

Step-by-step explanation:

Step 1: Find missing leg of left triangle

sin30° = x/16

16sin30° = x

x = 8

Step 2: Find missing leg of right triangle

8² + b² = 16²

b² = 192

b = 8√3

Step 3: Find <em>x</em> by taking the difference

8√3 - 8 = 5.85641

PLSSSSS HELP!!!!!!!!!
Anna11 [10]

Answer:

x=30º

∠CAB=60°

∠ACB=80°

Step-by-step explanation:

Because the angles of every triangle add up to 180º, we know that:

2x+20+2x=180-40\\ 4x=180-40-20\\ 4x=180-60\\ 4x=120\\ x=\frac{120}{4}

x=30º

Plug that in for x on both angles, and you will get

∠CAB=60°

∠ACB=80°

What is the answer to 11x+4+51+2x+8=180
Digiron [165]
Hi,

Work:

Equation;

11x + 4 + 51 + 2x + 8 = 180

Collect like terms and calculate sum of positive numbers.

13x + 63 = 180

Move constant +63 to the right side and change its sign.

13x = 180 - 63

Subtract numbers.

13x = 117

Divide both sides of equation with 13.

x = 9


Hope this helps.
