1 answer:
ASHA 777 [7]3 years ago
4 0

Answer:

x = 27

Step-by-step explanation:

30 \degree =  \frac{1}{2}  \{(5x + 10) \degree - (3x + 4) \degree \} \\ 30 \degree  \times 2=    \{(2x + 6) \degree \} \\ 60 \degree  =    (2x + 6) \degree \\ 60   =    2x + 6 \\ 2x = 60 - 6 \\ 2x = 54 \\ x =  \frac{54}{2}   \\  \huge \red { \boxed{x = 27}} \\

Round to the nearest hundreds place<br> Show your work<br> 4x = 7 - 8x - 27
faltersainse [42]

Answer:

x = 5

Step-by-step explanation:

4x = 7 - 8x - 27

1) Combine like terms (7 and -27). So, 7 + (-27) = -20.

        4x = 8x - 20

2) Subtract 8x from both sides of the equation. So, 4x - 8x = -4x.

        -4x = -20

3) Divide both sides by -4. So, -20 / -4 = 5.

        x = 5
