Solve the following equation for the given variable 3(x+6)=-9

Answers

Answer 1
Answer:

Answer:

x = -9

Step-by-step explanation:

3(x+6)=-9

Divide each side by 3

3/3 *(x+6)=-9/3

x+6 = -3

Subtract 6 from each side

x+6-6 = -3-6

x = -9

Answer 2
Answer:

Answer:

Step-by-step explanation:

so... 3(x+6)=-9

at 1st you do 3*x which is 3x then 3*6=18

all together is (3x+18)=-9

then get rid of brackets 3x+18=-9

after that take away 18 from both sides 3x+18=-9

                                                                 -18    -18

which is 3x = -27

then you divide 3 in the both side

its going to be 3x = -27

3/3=1x or x  then  -27/3 = -9

so x = -9

The marks on a combination lock are numbered 0 to 39. If the lock is at mark 19, and the dial is turned one mark clockwise, it will be at mark 18. If the lock is at mark 19 and turned 137 marks clockwise, at what mark will it be

Answers

Answer:

Mark 2  

Step-by-step explanation:

There are 40 marks on the lock.

Every full turn of 40 marks, the lock will come back to mark 19.

137/40 = 3R17

You can make three full turns (which is equivalent to doing nothing), and then you must move 17 more marks.

19 - 17 = 2

The lock will be at mark 2.

If the lock is at mark 19 and turned 137 marks clockwise, it will be at mark 2.

What is combination lock?

Combination lock is opened by rotating a set of number dials or marks graduated in a sequence.

The marks on a combination lock are numbered 0 to 39. If the lock is at mark 19, and the dial is turned one mark clockwise, it will be at mark 18. If the lock is at mark 19 and turned 137 marks clockwise,

137 = 40a +b where b<40

Divide 137 by 40, so we get the quotient 3 i.e., a =3.

Substitute a = 3 , the value of b is

b = 17

If the lock is at mark 19 and turned 137 marks clockwise, it will be at mark,

19-17 = 2

Thus, If the lock is at mark 19 and turned 137 marks clockwise, it will be at mark 2.

Describe how to simplify the expression 3^-6/3^-4a. Divide the bases and then add the exponents.
b. Keep the base the same and then add the exponents.
c. Multiply the bases and then subtract the exponents.
d. Keep the base the same and then subtract the exponents.

Answers

Answer:

The correct option is d. To simplify the given expression we should keep the base the same and then subtract the exponents.

Step-by-step explanation:

The given expression is

(3^(-6))/(3^(-4))

In the above expression we have common base 3 but the exponents are different.

According to the rule of exponent, if the numerator and denominator have same base and different exponent, then the base remains the same and the exponent of denominator subtracted from exponent of numerator.

(a^m)/(a^n) =a^(m-n)

Use this rule in the given expression.

(3^(-6))/(3^(-4))=3^(-6-(-4))

(3^(-6))/(3^(-4))=3^(-2)

Therefore the correct option is d.

Answer:

d or Keep the base the same and then subtract the exponents.
