Answer:

x= -9/4

x=−13−7x−5

x=−13+−7x+−5

x=(−7x)+(−13+−5)(Combine Like Terms)

x=−7x+−18

x=−7x−18

add 7 to both sides.

What’s the pattern of -1, -8, -27, and -64
AURORKA [14]

Hello from MrBillDoesMath!

Answer:

a(n) = (-n)^3  where n = 1,2,3,...


Discussion:

The pattern  1,8,27, 64... is immediately recognizable as the the cube of the positive integers. But this question has a minus sign appearing before  each entry, suggesting we try this:


 - 1  =  (-1)^3

 -8  = (-2)^3

-27  = (-3)^3

-64  = (-4)^3

That's what the problem statement asked for . The answer is equivalently

-1 * (n^3)


Thank you,

MrB

Given: If x, then not y, if not y, then z.<br> Y is true. So:
Fed [463]

If x, then not y, if not y, then z. Y is true. So: X is true, Z is True

<h3>How to Interpret Conditional Statements?</h3>

A conditional statement is a type of structure to express the relationship between two dependent variables. Its structure is as follows:

If P, then Q...

Now, from the question we are told that;

If x, then not y, if not y, then z.

Y is true. So:

Now, when looking at conditional statements in depth, and comparing to this question we can easily see that since Y is true, then it means that if X is true, then Z is also true.

Thus,

If x, then not y, if not y, then z.

Y is true. So: X is true, Z is True

Jacob makes a scale drawing for a crate with a scale
olga55 [171]

Answer:

  6 inches long and 4 inches wide

Step-by-step explanation:

The dimensions of the actual crate are 20 times those on Jacob's drawing. The dimensions on the builder's drawing are 1/10 of those, so (1/10)(20) = 2 times the dimensions on Jacob's drawing.

The dimensions on the builder's scale drawing are 6 inches long by 4 inches wide.

PLEASE help a girl out! :)What is the actual area of the room?
andrey2020 [161]

Answer:

=75ft^{2}

Step-by-step explanation:

Area is found by mulitplying width and height.

A=7.5(5)\\

A=37.5\\in

The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.

37.5in x \frac{1ft}{0.5in} =75ft^{2}
