Answer:

check explanation for answers

Step-by-step explanation:

ratios are pretty much just simplified fractions

so just turn the numbers into a fraction and simplify them!

trumpets/violins are 5:3

flutes/clarinets are 17:13

trombones/trumpets are 2:5

violins/total instruments are 12:85

some friends plotted the locations of their house on a map. brianna's house is at (1,6), Jordan's house is at (5,3). What is one

Morgarella [4.7K]

Let
A (1,6)------> location brianna's house on a map
B (5,3)------> location Jordan's house on a map

we know that
One possible path from brianna's house to jordan's house it's a straight line ( the shortest distance)

using a graph tool
see the attached figure

find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]d=√25----> d=25 units

the distance from brianna's house to jordan's house is 25 units

OMG PLS HELP WITH THIS IM PANICKING OMG I GOT A F IN MATH MY MOM JUST YELLED AT ME IM CRYING PLS HELP WITH THS- PLSS TELL ME WHA

Savatey [412]

Answer:

Ok, here we can see that Mr. Jones has $3,553 in his account, and he actually needs $18,469 to buy the car.

One way of representing this is:

Get a ruler, and draw a line that measures 3.553 cm (or close to it, it shouldn't be exact)

Now draw a line that measures 18.469 cm (again, this shouldn't be exact)

The difference between these lines represents the amount of money that Mr. Jones needs to save.

Now, how we find exactly the quantity?

Let's take the total cost of the car:

$18,469

Now let's subtract the amount of money that Mr. Jones already has:

$18,469 - $3,553 = $14,916

This is the amount of money that Mr. Jones needs to save if he wants to buy the car.

Which statement represents the simplified form of the given equation and correctly describes the solution?

exis [7]

Hence the correct answer is:

D. 6=6; infinite real solutions

Further explanation:

In order to find the simplified form of the equation we have to isolate the variable on one side of the equation.

Given equation is:

$9x+6=3(3x+2)$

Taking 3 common on left hand side

$9x+6=9x+6\\9x-9x+6=6\\6=6$

The equation has infinite real solutions.

Hence the correct answer is:

D. 6=6; infinite real solutions

Keywords: Solution of equation, infinite solutions
