Answer:
5. 12
6. 12
7. 20
Step-by-step explanation:
5. if it's the friend does 3 cars for every 2 cars you do, then its multiplying itself. so 4 for you would be 6 for the friend, as for 6 to 9, and 8 to 12.
6. just like in 5 it's 5 shirts for every 2 sweaters. so 10 shirts would be 4 sweaters, 15 would be 6, 20 would be 8, 25 would be 10, and 30 would be 12.
7. this ratio is 5 olives for every 3 croutons. since u have 12 croutons, that's 3 times 4 so you do the same thing to the olives. 5 times 4 which equals 20 olives for 12 croutons.
Hi there!
Answer:
4x + 5 = 25
Subtract 5 from both sides:
4x + 5 - 5 = 25 - 5
4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5.
Rectangle B = 56inches by 28inches
It’s pretty easy you just multiply 8 by 7 and 4 by 7.
Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .
<u>Step-by-step explanation:</u>
Here we have , Leanne runs a lap in 12 minutes. Kory runs a lap in 9 minutes. We need to find out that If they both start running at 10 am, at what time will they both cross the start together again . Let's find out:
Kory runs a lap in 9 minutes and , Leanne in 12 minutes , in order to find at what time will they both cross the start together again we will find LCM of 9 & 12 :
⇒
⇒
So ,LCM of 9 & 12 is 36 .That means Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .
In clear way , Kory will run race as :
1st lap = 9 minutes
2nd lap = 18 minutes
3rd lap = 27 minutes
4th lap = 36 minutes , i.e. at 10:36 am he'll complete his 4th lap
For , Leanne
1st lap = 12 minutes
2nd lap = 24 minutes
3rd lap = 36 minutes i.e. at 10:36 am he'll complete his 3rd lap .
This means Kory & Leanne will meet at 10:36 am completing there 4th and 3rd lap respectively .
