How do i solve 12+4x=30+12

Mathematics
1 answer:
Elza [17]3 years ago
4 0

Answer:

x = 15/2

Step-by-step explanation:

Solve for x:

4 x + 12 = 42

Subtract 12 from both sides:

4 x + (12 - 12) = 42 - 12

12 - 12 = 0:

4 x = 42 - 12

42 - 12 = 30:

4 x = 30

Divide both sides of 4 x = 30 by 4:

(4 x)/4 = 30/4

4/4 = 1:

x = 30/4

The gcd of 30 and 4 is 2, so 30/4 = (2×15)/(2×2) = 2/2×15/2 = 15/2:

Answer: x = 15/2

-6x+7(1-x)=-4(x-4) if you help thank you so much!!!
salantis [7]
Answer:
-1

Step by step explanation:
Rearrange terms
-6x+7(-x+1)=4(x-4)
Distribute
-6x - 7x + 7 = - 4(x-4)
Combine like terms:
−13+7=−4(−4)
Distribute:
−13+7=−4+16
Subtract 7 from both sides of the equation
−13+7−7=−4+16−7
Simplify
−13=−4+9
Add 4x to both sides of the equation
−13+4=−4+9+4
Simplify
Combine like terms
Combine like terms
−9=9
Divide both sides of the equation by the same term
9x/-9 = 9/-9
Simplify
X= -1​

Any REAL help on #16 above??? Can someone check my answer?
babymother [125]

Answer:

The answer to your question is:th first option is correct.

Step-by-step explanation:

Here we have and hyperbola with center (0, 1), and the hyperbola is horizontal because x² is positive.

Equation

y - k = ±\frac{b}{a} (x - h)

Process

Find a, b

                a² = 9    

               a = 3

                b² = 5

              b = √5

              h = 0    and k = 1

Substitution

              y - 1 = ±\frac{√5}{3} (x - 0)

Equation 1

            y = \frac{\sqrt{5} }{3} x + 1

Equation 2

           y = - \frac{\sqrt{5} }{3} x + 1
