Answer:

13.667 ~ 13.7

Step-by-step explanation:

38 + 5b + 101 - 2b = 180

139 + 3b = 180

3b = 41

Divide both sides by 3

b = 13.667 ~ 13.7

Triangle sum (3x+1)^0+(10x-11)^0+(3x-2)^0=180
svetlana [45]

Answer:

  • x = 12
  • 3x+1 = 37°
  • 10x-11 = 109°
  • 3x-2 = 34°

Step-by-step explanation:

Perhaps you want to know the value of x or the measures of the angles?

__

Simplifying the given equation, you get ...

  (16x -12)° = 180°

  16x = 192 . . . . . . . divide by °, add 12

  x = 12

  (3x+1)° = (3·12+1)° = 37°

  (10x-11)° = (10·12-11)° = 109°

  (3x-2)° = (3·12-2)° = 34°

x is 12, and the angle measures are 37°, 109°, 34°.

What is -12(x-12)=-9(1+7x)​
katen-ka-za [31]

Answer:

-3

Step-by-step explanation:

-12(x-12)=-9(1+7x)

-12x+144=-9-63x

-12x+63x=-9-144

51x=-153

x=-153/51=-3

Solve the system of equations using elimination: -8x-4y=4 and -5x-y=-11.
ziro4ka [17]

The solutions to the given system of equations are x = 4 and y = -9

<h3>Simultaneous linear equations</h3>

From the question, we are to determine the solutions to the given system of equations

The given system of equations are

-8x-4y=4  --------- (1)

-5x-y=-11   --------- (2)

Multiply equation (2) by 4

4 ×[-5x-y=-11 ]

-20x -4y = -44  -------- (3)

Now, subtract equation (3) from equation (1)

-8x -4y = 4  --------- (1)

-(-20x -4y = -44)  -------- (3)

12x = 48

x = 48/12

x = 4

Substitute the value of x into equation (2)

-5x -y = -11

-5(4) -y = -11

-20 -y = -11

-y = -11 + 20

-y = 9

∴ y = -9

Hence, the solutions to the given system of equations are x = 4 and y = -9

How do you solve these
IRINA_888 [86]
In the first equation, you can tell that the x's are being multiplied by 3 to get to the y's so the blank will be 9. The second table would not be a function since all the x values are not being multiplied by the same number to get the y value. Hope this helps!
