Mathematics

Snezhnost [94]3 years ago
5 0

Step-by-step explanation:

it's late but I hope it helps :)

imagine that the > symbol is just an equal sign

so for example

x+2>4

will look like

x+2=4

and you solve normally

×=2

now we bring the symbol back

x>2

but if you multiple or divide by a negative the sign flips

so say you have

-2x>4

make it into

-2x=4

solve

x=-2

but instead of >

you put

x < -2

A polygon has an interior angle sum of 9000. How many sides does it have
SSSSS [86.1K]

Answer:

52

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here the sum = 9000°, thus

180° (n - 2) = 9000° ( divide both sides by 180° )

n - 2 = 50 ( add 2 to both sides )

n = 52

A group of kids do a car wash. They charge $4.50 for each small car they wash and eight dollars for each large car or SUV in the
Basile [38]

Answer:

Step-by-step explanation:

Let x and y represent the numbers of small and large cars washed, respectively.

We know that:

$4.50x + $8y = $420

But we don't know the relationship between x and y.  We need more information (e.g., they washed twice as many small cars and large).  Otherwise we have one equation and two unknowns.  Since there are two unknowns, we can't determine a "slope" of the line.  With all the water and soap, the most we could possibly say it will be a slippery slope.

I solved using brainly but i need to show my work what are the steps in solving please
notka56 [123]

Answer:

Step-by-step explanation:

to find the inverse first switch the x and y

y=log(x+3) inverse is x=log(y+3)

then change to exponential form to solve

log_{a} b=c turns toa^{c}=b

a is 10

b is y+3

c is x

10^{x} =y+3  subtract 3 from both sides

10^{x} -3=y
