quarters and how many were nickels.

Answers

Answer:

0 quarters28 nickels

Step-by-step explanation:

Let d represent the number of dimes. Then 40-d is the number of nickels. The value is ...

0.10d +0.05(40 -d) = 2.60

0.05d = 0.60 . . . . . subtract 2.00

d = 0.60/0.05 = 12 . . . . . the number of dimes

40 -d = 40 -12 = 28 . . . . .the number of nickels

There are 0 quarters. There are 28 nickels.

What two numbers have a sum of -7 and a difference of 14?

Answers

Answer:

The sum of two numbers is 14 and their difference is 10

Step-by-step explanation:

"2 numbers (x and y)

x+y = 14

and x-y + 10

If you each equation by positive 2, one gets 2x+2y = 28 and 2x-2y = 20

The 'y-terms' cancel out or equal zero when adding, so 4x = 48, divide by 4 on each side and x or the first number equals 12.

Plug 12 back into the equation for 'x' and subtract 12 on both sides so that y=2

The difference of 12-2=10 and the addition of 12 and 2 equals 14"

hopes this helps

The first number, x, is 3.5. The other number, y, is 10.5.
X+y=-7
X-y=14.
Those are the two equations. If you use the elimination method, and add those two equations together, the resulting equation is 2x=7. That means the first variable is 3.5. So, 3.5-y=-7, so that means y is -10.5. If you plug that in with the other equation then it comes out as true.

If my pay rate is $9 an hour and I worked 7 hours and 45 minutes. How much money did I make?

Answers

Answer:

Step-by-step explanation:

Answer:

12 feet

Step-by-step explanation:

use the pythagorean theorem to figure out what the hypotenuse is

3.5^2+3.5^2=x^2

12.25+12.25=x^2

25=x^2

x=5

now that you know the hypotenuse, you can find the perimeter by adding up all the sides

3.5+3.5+5=12

Select the correct choice.

Answers

Step-by-step explanation:

To find how much 75% we multiply 100 with 75 and divide it with 100

75 × 10 ÷ 100 = 7.5

we need to do same with Noah's money

25 × 30 ÷ 100 = 7.5 Noah is correct, they have same amount.

Sumí is making 8 clay pots in art class. 3 are finished. She has 75 minutes left to work and wants to spend an equal amount of time on each remaining pot. Which is the best way to find how many minutes suki should spend on each remaining pot.

Answers

Answer:

Subtract 3 from 8, then divide 75 by 5.

Step-by-step explanation:

First, subtract 3 from 8 since she finished 3 already.

8-3=5

This means that Sumi has 5 more pots to make. Since she has 75 minutes left, and she wants to finish all the pots in the same amount of time, we can divide 75 by 5.

75/5=15

Sumi should finish each pot in 15 minutes.

This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion. This is nonresponse bias because many who are asked about the ticket tax may choose to not provide a response.
