Rebecca has 25 coins, all nickels and dimes. the total value of the coins is $3.60. how many of each type of coin did rebecca have?

Error in given values.

Step-by-step explanation:

Let number nickel coins = x

Let number dime coins = y

Given that total number of coins is 25 so that means

x+y=25

or x=25-y...(i)

We know that 1 nickel = $0.05

then value of x nickels = 0.05x

We know that 1 dime = $0.10

then value of y dimes = 0.10y

Then total value of both type coins will be 0.05x+0.10y

Given total value is $3.60

So we get

0.05x+0.10y=3.60 .

multiply both side by 100 to remove decimals

5x+10y=360

divide both sides by 5

x+2y=72...(ii)

now we just need to solve both equations:

plug (i) into (ii)

x+2y=72

25-y+2y=72

25+y=72

y=47

we are getting 47 coins of dimes.

But we have been given that there are only 25 coins which is not possible.

So there must be some misprinting in the question.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
