Answer:

You will need 39 nickels and 13 dimes.

Step-by-step explanation:

First you would find the number by choosing a number for example 10 so 10*5 which is 50 cents because, we are talking money here

So 39*5=195 which converts to $1.95

Next you would write that number down and divide 39 by 3 which would be 13

Then 13*10 would be 130 which would be converted into $1.30

Lastly you would add $.195 and $1.30 which would be $3.25

Therefore your answer is 39 nickels and 13 dimes

Can u help with it plz I really need help ​

Answer:

let angle e be x

x+4x+10=180°[by linear pair]

5x+10=180°

5x=180-10

5x=170

x=170/5

x=34

angle E=34°

angle E+angle C+angle D=180°[by angle sum property]

34°+70°+2x=180°

104°+2x=180°

2x=180°-104

2x=76°

angle d=76°

Is the relation a function?
Margaret [11]
No; a domain value has two range values.

x = -2 then y = 1 and 2

they would form a vertical line, which tells us that it's not a function
