Answer:

True.

Step-by-step explanation:

Multiply 3 by 6x-2 and you get (18x-6). Subtract 7 from -6 gives you 13, which equals 18x-13.

Answer:

True

Step-by-step explanation:

You want to get the x's by themselves, so first you have to use the distributive property.

3 x 6x = 18x

3 x 2 = 6

So now the equation should look like

18x - 6 - 7 = 18x - 13

So now you have to get the x's by itself by adding or subtracting like terms.

- 6 - 7 = -13

18x - (-13) = 18x - 13

+ (-13) + (-13)

-----------------------

18x = 18x

18/18 18/18

x = 1

Now plug the numbers in

3(6(1) - 2) - 7 = 18(1) - 13

5 = 5

Step 1. Use Division Distributive Property $( \frac{x}{y} ) ^{a} = \frac{ x^{a} }{ y^{a} }$

Step 2. Simplify $3^{2}$ to $9$

$\frac{1}{9} *18+( \frac{1}{2} ) ^{2}*4 
$

Step 3. Use Division Distributive Property $( \frac{x}{y} ) ^{a} = \frac{ x^{a} }{ y^{a} }$

$\frac{1}{9} *18+ \frac{1}{ 2^{2} } *4$

Step 4. Simplify $2^{2}$ to $4$

$\frac{1}{9} *18+ \frac{1}{4} *4$

Step 5. Simplify $\frac{1}{9} *18$ to $\frac{18}{9}$

$\frac{18}{9} + \frac{1}{4} *4$

Step 6. Simplify $\frac{18}{9}$ to $2$

$2+ \frac{1}{4} *4$

Step 7. Simplify $\frac{1}{4} *4$ to $1$

$2+1$

Step 8. Simplify

$3$

Done! Your answer is 3

A large rectangular swimming pool is 1,000 feet long, 100 feet wide, and 10 feet deep. The pool is filled to the top with water.

MArishka [77]

Answer:

It's a simple question. This swimming pool is basically a rectangular cuboid. Length x Width x Height = how much water it will hold.

Water = 1000000 feet^(3)

Step-by-step explanation:

1000 x 100 x 10 = 1000000 feet^(3)

or you could just converted to meters cube which should be 28316.85 (ish).
