-79 = 7x + 3(4x - 1) Help

Dmitry [639]

Answer:

x = - 4

Step-by-step explanation:

-79 = 7x + 3(4x - 1)

-79 = 7x + 12x - 3 Distribute 3 to the paranthesis

-79 = 19x - 3 Add like terms

-76 = 19x Add 3 to both sides

- 4 = x Divide 19 to both sides

Rewrite the following without an exponent. 6^-2 Please answer ASAP!

julia-pushkina [17]

Answer:

Rewriting $6^{-2}$ without an exponent we get $\mathbf{\frac{1}{36}}$

Step-by-step explanation:

We need to rewrite the following without an exponent. $6^{-2}$

We need to solve the exponent to find the result.

We know the exponent rule: $a^{-b}=\frac{1}{a^b}$

Now using this rule to solve the equation:

$6^{-2}\\=\frac{1}{6^2}\\We \:know \:that\:6^2 = 6\times 6=36\\=\frac{1}{36}$

So, Rewriting $6^{-2}$ without an exponent we get $\mathbf{\frac{1}{36}}$

$6z + 7 = 8z - 9$

$8z - 9 = 6z + 7$

Add sides 9

$8z - 9 + 9 = 6z + 7 + 9$

$8z = 6z + 16$

Subtract sides 6z

$- 6z + 8z = - 6z + 6z + 16$

$2z = 16$

Divide sides by 2

$\frac{2z}{2} = \frac{16}{2} \\$

$z = 8$

Thus ;

$NP = 8z - 9$

$NP = 8(8) - 9$

$NP = 64 - 9$

$NP = 64 - 4 - 5$

$NP = 60 - 5$

$NP = 55$

Done...
