Rewrite the following without an exponent. 6^-2<br> 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 $\mathbf{\frac{1}{36}}$

-3r-8(8r+8)=-9(-4+9r)

natulia [17]

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)

Need help not sure what to do

Rama09 [41]

5a)

2x + 94 = 7x + 49 (vertical angles are equal)

2x - 7x = -94 + 49

-5x = -45

x = 9

Answer

5b)

4y + 7x + 49 = 180 (supplementary angles, sum = 180)

4y + 7(9) + 49 = 180

4y + 112 = 180

4y = 68

y = 17

Answer

x = 6x - 290 (vertical angles are equal)

-5x = -290

x = 58
