Answer:
3 or 3/1 (the 1 is the denominator)
Step-by-step explanation:
the shape got 3 times bigger. let me know
Answer:
9/35ths of the total amount ![(\frac{9}{35} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B35%7D%20%29)
Step-by-step explanation:
essentially, we are finding 3/5ths of 3/7ths
"of" in math is an indication to multiply
so,
×
= ![\frac{9}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B35%7D)
9/35ths of the total amount of vehicles are red cars.
Answer:
4 songs
Step-by-step explanation:
Given data,
Adventure play sells mp3 = $18
Charges per song = $3.25
King music sell Mp3 = $23
Charges per song = $2
Let number of songs be Y, then we can calculate by using following method,
Adventure play MP3 cost + charges per song = Kings Music MP3 cost + charges per song
By putting the value, we get
$18 + $3.25 Y = $23 + $2 Y
By solving the equation,
$3.25 Y - $2Y = $23 - $18
$1.25 Y = $5
Y = $5 ÷ $1.25
Y = 4 songs
Hence, for 4 songs the cost be same.
REASONS:-
1ST STEP
![6x + 7 = 8x - 17](https://tex.z-dn.net/?f=6x%20%2B%207%20%3D%208x%20-%2017%20)
GIVEN LHS = RHS
2ND STEP
![7 = 2x - 17](https://tex.z-dn.net/?f=7%20%3D%202x%20-%2017)
Bez +ve 6x when move to another side will change to -ve so it reduces 8x to 2x
3RD STEP
![24 = 2x](https://tex.z-dn.net/?f=24%20%3D%202x%20)
Bez -ve 17 when move to another side will change to +ve so it increases 7 to 24
4TH STEP
![12 = x](https://tex.z-dn.net/?f=12%20%3D%20x)
Bez 2 in multiplication when move to another side will change to division so it reduces 24 to 12
5TH STEP
![x = 12](https://tex.z-dn.net/?f=x%20%3D%2012)
it the answer we obtained after solving
Remember when you learning about the "Least Common
Multiple" and you wondered when in the world you would
ever need to use it ?
Well, here you are ! Hello !
The next time they will cross the starting line together is the
LCM (Least Common Multiple) of 30 and 40 .
Do you remember how to find it ?
Here's one easy way:
Count by 30s until you come to a number that's divisible by 40 .
Laura's first lap. . . . . . . . 30 seconds . . . not divisible by 40
Laura's two laps . . . . . . . 60 seconds . . . not divisible by 40
Laura's three laps. . . . . . 90 seconds . . . not divisible by 40
Laura's four laps. . . . . . 120 seconds . . . divisible by 40
After 120 seconds, Laura has completed four laps,
Shelby has completed only three laps.
