Debbi has 17 coins that are all either quarters or dimes. the total value of her money is 3.20

AlladinOne [14]

Answer:

There are 10 quarters and 7 dimes

Step-by-step explanation:

The question asks for the number of quarters and the number of dimes.

Quarters and Dimes equal 17, so let number of quarters be "q" and number of dimes be "d", so we can write:

q + d = 17

We know quarters are worth 0.25 and dimes are worth 0.10 (in dollars) and total value of the coins are 3.20 dollars, thus we can write:

0.25q + 0.10d = 3.20

Let's write the first equation as:

q = 17 - d

Now we substitute this into 2nd equation and solve for d:

0.25q + 0.10d = 3.20

0.25(17 - d) + 0.10d = 3.20

4.25-0.25d+0.10d = 3.20

-0.15d = -1.05

d = 7

Now using this value of d, we now find q:

q = 17 - d

q = 17 - 7

q = 10

There are 10 quarters and 7 dimes

Sindrei [870]

Answer:

C. The likelihood of having brown eyes is 35%

Step-by-step explanation:

Add the total number of people, which gives you 50.

To find the percent of brown-eyed people out of 50, divide 35 by 50, then multiply the result (0.7) by 100 to get 70%.

70% of people are brown-eyed, thus, C is a false statement.

The sum of 3 consecutive odd integers is 18 less than five times the middle number. Find the three integers

Andreyy89

n, n + 2, n + 4 - three consecutive odd ntegers

n + (n + 2) + (n + 4) = 5(n + 2) - 18 |use distributive property

n + n + 2 + n + 4 = (5)(n) + (5)(2) - 18

3n + 6 = 5n + 10 - 18

3n + 6 = 5n - 8 |subtract 6 from both sides

3n = 5n - 14 |subtract 5n from both sides

-2n = -14 |divide both sides by (-2)

n = 7

n + 2 = 7 + 2 = 9

n + 4 = 7 + 4 = 11

Answer: 7, 9, 11.
