Answer: c = 8

Step-by-step explanation:

Simplifying

9c + -3c = 48

Combine like terms: 9c + -3c = 6c

6c = 48

Solving

6c = 48

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Divide each side by '6'.

c = 8

Simplifying

c = 8

Answer: 8

Step-by-step explanation:

9c - 3c is 6c, so 6c = 48, divide both sides by six and you get c = 8

Answer:

The correct option is commutative property.

Step-by-step explanation:

The expression that Renee is simplifying is:

(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})

It is provided that, Renee recognizes that 7 and \frac{1}{7} are reciprocals, so she would like to find their product before she multiplies by \frac{13}{29}.

The associative property of multiplication states that:

a\times b\times c=(a\times b)\times c=a\times (b\times c)

The commutative property of multiplication states that:

a\times b\times c=a\times c\times b=c\times a\times b

The distributive property of multiplication states that:

a\cdot (b+c)=a\cdot b+a\cdot c

The identity property of multiplication states that:

a\times 1=a\\b\times 1=b

So, Renee should use the commutative property of multiplication to find the product of 7 and \frac{1}{7},

(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})=(7\times\frac{1}{7})\times\frac{13}{29}=\frac{13}{29}

Thus, the correct option is commutative property.
