What is
5 times 20/25

Answers

Answer 1
Answer: just multiply top by top and bottom by bottom

first simplify them as much as possible for ease
20/25=5/5 times 4/5=1 times 4/5=4/5
5=5/1
5 times 4/5=5/1 times 4/5=(5*4)/(1*5)=20/5=5/5 times 4/1=1 times 4/1=4
Answer 2
Answer: Make 5 a fraction: 5=5/1. Multiply both fractions: 5/1*20/25=100/25, 100/25 simplified is 4/1. 4/1 is the same as 4. Therefore, 5 times 20/25=4

A) let x=months let y=costy=mx+by= 20x+ 60Remember 20 is the variable which means in this case every month it cost 20$ and 60 is the constant which means you only pay it onceB) let x= Months let y= costy=10x + 150C) platinum gymy= 20x+60y=20(1)+60y=20+60y=80Superfity=10x+150y=10(1)+150y=10+150y=160Therefore Tom will pay less after the first monthD) y=y solve for xy=20x+60y=10x+15020x+60=10x+150-10x. -10x10x+ 60=150-60. -6010x=9010x/10=90/10X=99 monthsPick any equation and sub in xY=10x+150Y=10(9)+150Y=90+150Y=240240$Know that you only have to do one equation to find y but if you want to show both you canTherefore there is a period where Tom and Edward paid the same amount, after nine months they would both pay $240E) if they plan on going to the gym 9 months and less the best deal gym is platinum gym but if they want to go for more then 9 months then the best deal gym is super fit

Write 7 as a fraction with the 9 in the denominator

so 7=7/1
to put a 9 in the bottom and make the fraction stay the same, multiply it by 1
or 9/9 since 9/9=1 so
7/1 times 9/9=(7 times 9)/(1 times 9)=63/9
answe ris 63/9
63/9 would be the answer because 63 divided by 9 would be equivalent to 7/1 or 7.

First find the volume of the pool. To do so, multiply the length, times the width, times the height. In this case, it would be 12*15*5 and you get 900 cubic meters.
If the pool is being filled with 36 cubic meters of water per hour, you divide 900 by 36. You get 25 hours.
To check your work, multiply 25 hours and 36 cubic meters of water. You get 900 cubic meters, which is the area of the pool meaning it is full.
