3) k - t2x = m​

Answers

Answer 1
Answer:

Answer:

#1

{ \tt{a - x = y}} \n \n { \boxed{ \tt{x = a - y}}}

#2

{ \tt{m = k - x}} \n \n { \boxed{ \tt{x = k - m}}}

#3

{ \tt{k - {t}^(2)x = m }} \n { \tt{ {t}^(2) x = k - m}} \n \n { \boxed{ \tt{x = \frac{k - m}{ {t}^(2) } }}}
Answer 2
Answer:

Step-by-step explanation:

1) a-x=y

a-a-x=y-a

-x=y-a

x= -(y-a)

2) m=k-x

-x=m-k

x= -(m-k)

Jonathan and Laura are three miles apart and are traveling towards each other. If Jonathan travels m miles, write an expression to represent how far Laura has traveled when they meet each other.

Answers

The sum of the number of miles that should be traveled by Jonathan and Laura to total 3 miles together should be expressed as,
                                  m + x = 3
By subtracting m from both sides of the equation, we get
                                        x = 3 - m
Now, we see that the expression for the distance that Laura traveled is,
                                         3 - m

Theo used to drive 60 miles to work each day. His new home is now 20 miles awayfrom his job. What is the percent of
decrease in the distance Theo travels to
work? Round to the nearest tenth if
necessary.

Answers

The percentage of decrease in the distance Theo travels to work is 66.7%.

Used concept of percentage;

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.

Given that;

Theo used to drive 60 miles to work each day.

And, His new home is now 20 miles away from his job.

Hence the percentage of decrease in the distance Theo travels to work is,

P = (60 - 20)/60 x 100

P = 40/60 x 100

P = 66.7%

So, The percentage of decrease in the distance Theo travels to work is 66.7%.

Why is math so hard?

Answers

because its supposed to be to make us suffer
I wouldn't consider math hard it is just a challenge and sometimes more complex that you have to dig a little deeper to find the answer it won't always be right there. I have to be honest that I am not a fan of math but I learned that I need math in my life because it is everywhere. Remember that math is like building blocks it starts off in kindergarten with adding then subtracting, multiplying, dividing. It continues on with your life. You just need to work with it and soon it won't be as complicated.
