What is the shortset 1/3 2/5 3/10 or 1/4

Answers

Answer 1
Answer: (1)/(4) because (2)/(5) , (3)/(10), (1)/(4) can all be made into the LCM of 20 and turns the fractions into(8)/(20), (6)/(20), (5)/(20) respectively. This makes(1)/(4) the smallest of that group. That just leaves (1)/(3), (1)/(4). By using the exact same process, you use 3 and 4's LCM of 12 and get (4)/(12), (3)/(12). That makes (1)/(4) the smallest of the group.
Answer 2
Answer: 3/10 is least greatest becasue it is divided up into more sections with less colored in

Daren is 3 years older than Tom. 3 years ago Leah will be 14 less than 3 times Darren's age. 5 years ago, Leah was 2 years less than 2 times Tom. How old will Leah be 4 years from now?

Answers

answer

5

set up equations

daren is 3 years older than tom

D = 3 + T

3 years ago leah will be 14 less than 3 times darren's age

L - 3 = 3(D - 3) - 14

L - 3 = 3D - 9 - 14

L = 3D - 9 - 14 + 3

L = 3D - 20

5 years ago, leah was 2 years less than 2 times tom

L - 5 = 2(T - 5) - 2

L - 5 = 2T - 10 -2

L = 2T - 10 - 2 + 5

L = 2T - 7

find leah's current age

set L = 3D - 20 and L = 2T - 7 equal to each other

3D - 20 = 2T - 7

plug 3 + T into D using the equation D = 3 + T

3D - 20 = 2T - 7

3(3 + T) - 20 = 2T - 7

9 + 3T - 20 = 2T - 7

T = - 7 - 9 + 20

T = 4

plug T back into L = 2T - 7 to find leah's current age

L = 2T - 7

L = 2 * 4 - 7

L = 8 - 7

L = 1

leah's age 4 years from now

add 4 to leah's current age

I have no idea what you mean right now.  Can you get a picture of whatever it is you are having trouble on?

1) 2x + 8y = 20 what's the solution so confused
y = 2

Answers

if y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20 
2x + 16 = 20 
2x = 20 - 16
2x = 4 
x = 4/2 
x=2 :)))
i hope this is helpful
have a nice day
2x + 8y = 20 
y = 2

Substitute y with its value.

2x + 8y = 20
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x = 2

x = 2; y = 2

2x + 8y = 20
2(2) + 8(2) = 20
4 + 16 = 20
20 = 20

I^37 is what?


A: i

B: -i

C: 1

D: -2

Answers

First off, i is equal to the square root of -1. The square of i, therefore is -1. An even exponent applied to i is -1. An odd exponent applied would denote -i, therefore. Your answer should be B.
