An airplane flies with a constant speed of 620 miles per hour. How long will it take to
travel a distance of 310 miles? Give your answer in minutes or hours.
Answers
Answer:
30 minutes
Step-by-step explanation:
Alright lets start by laying out what the problem gives us :
A plane flies 620 mph.
It is asking how long it will take to travel 310 miles.
We need to give our answer in minutes or hours.
So lets take mph and look at the full meaning "Miles per hour"
An hour has 60 minutes in it.
So really it is saying miles per 60 minutes as well as miles per hour
So you could say the plane is traveling 620 miles every 60 minutes.
So now lets look at the number 310.
Just looking at it I can tell you that 310 looks very close to half of 620, in fact it is exactly half!
So lets divide the 620 mph by the 310 miles it is asking and we get 2! Proving that 310 is half of 620.
Alright now lets divide both the number of miles and number of minutes :
620 miles per 60 minutes
divided by 2 both miles and minutes
310 miles per 30 minutes
So this is your answer. After this you get that it would take 30 minutes to travel 310 miles in a plane going 620 miles per hour!
I hope this helps and I could help you understand it. :)

Consider the sequence of steps to solve the equation: 2(x – 4) + 6x = 9x – 10
Given = 2(x - 4) + 6x = 9x - 10
Step 1 = 2x - 8 + 6x = 9x - 10
Step 2 = 2x + 6x - 8 = 9x - 10
Step 3 = 8x - 8 = 9x - 10
Step 4 = 8x – 8x - 8 = 9x - 8x - 10
Step 5 = 0 - 8 = x - 10
Step 6 = -8 = x - 10
Step 7 = -8 + 10 = x - 10 + 10
Step 8 = 2 = x + 0
Step 9 = 2 = x
Which step in solving this equation is justified by the distributive property
Answers
Answer:
Step 1
Step-by-step explanation:
The problem distributed 2 into x and -4 which resulted in 2x - 8
3x+4=9x-8= ????????????
Answers
Simplifying
3x + 4 = 9x + -8
Reorder the terms:
4 + 3x = 9x + -8
Reorder the terms:
4 + 3x = -8 + 9x
Solving
4 + 3x = -8 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
4 + 3x + -9x = -8 + 9x + -9x
Combine like terms: 3x + -9x = -6x
4 + -6x = -8 + 9x + -9x
Combine like terms: 9x + -9x = 0
4 + -6x = -8 + 0
4 + -6x = -8
Add '-4' to each side of the equation.
4 + -4 + -6x = -8 + -4
Combine like terms: 4 + -4 = 0
0 + -6x = -8 + -4
-6x = -8 + -4
Combine like terms: -8 + -4 = -12
-6x = -12
Divide each side by '-6'.
x = 2
Simplifying
x = 2

If JK = 8x + 24 and NO = 20, what is the value of x?
Answers
Answer:
x=2
Step-by-step explanation:
So..
NO=1/2 of JK because the two segments are parallel
Therefore because you have NO plug that into..
NO=1/2JK
YOU GET
1/2JK=20 multiply 2 so you can isolate JK
JK=40
Then plug that back into your JK=8x+24
40=8x+24 next subtract 24 on both sides
8x=16
x=2

using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded monthly?
Answers
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx

Write the English phrase as an algebraic expression. Then, simplify the expression. Let x represent the number.
The difference between the product of five and a number and three times the number
What is the algebraic expression?
Answers
Answer:
5x-3x = 2x
Step-by-step explanation:
"The difference" = the substraction of two numbers
(something) - (something)
"The difference between the product of five and a number"
By product means multiplication. So, the multiplication of five and a number. Before, you have been told to represent the number with "x", and thats what you will do now.
(5*x) = (5x)
(5x) - (something)
"The difference between the product of five and a number and three times the number"
With three times the number, we mean the same letter "x" & three times will be the amount of times we will multiply it. So, by the end we will have:
(5x)-(3x)
Now we just rest them
5x-3x= 2x
Hope it was helpful ;)
The difference between the product of five and a number and three times the number will be two times the number and algebraic expression will be 5x - 3x = 2x.
What is an expression?An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.
In other meaning, expression is very useful to determine the end or root value of constraint.
For example 3x +5y
The constraint of expression is represented as = or <, >.
Given that,
x is that number,
Five times the number = 5x
Three times the number = 3x
Now,
Difference ⇒ 5x - 3x = 2x
Hence "The algebraic expression is 5x - 3x = 2x and The difference between the product of five and a number and three times the number will be two times the number".
