To get the answer you have to multiply the number of coins per roll which is 40 by the number of rolls which is 25. So the equation you get is 40*25. And the answer you get is 1000

well, we know a nickel is 5 cents, a dollar is 100 cents, how many times does 5 go into 100? 100 ÷ 5 = 20, twenty times, so there are 20 nickels in 1 dollar.

these rolls each have 40 nickels though, namely 20 + 20 = 1 dollar + 1 dollar, so there are 2 dollars in one of these rolls.

we know there are 2 bucks in a roll of nickels, how many in 25 rolls? 25 * 2 = $50.

Answer:

79.5 + 5.5x = Y

Step-by-step explanation:

Sumo wrestler gained 5.5 kg per month

After 11 month, he weighed 140 kg.

Let x be his current weight.

Then x + 11(5.5) = 140

x = 140 - 60.5

x = 79.5

If Y is the weight of the wrestler after t months, then the linear equation would be:

79.5 + 5.5t = Y

Type the correct answer in the box. Use numerals instead of words for numbers.

Answer:

x=-16

Step-by-step explanation:

The given equation is:

x = 8a

which was written to find the value of x.

We have to find the value of x when the value of a is inserted as -2

So, putting the value

x = 8(-2)

x= -16

So the value of x when a = -2 is -16 ..

It would appear your original equation is in Y=MX+b form, where M=2
