Lin lines the bottom of her first pan with aluminum foil. The area of the rectangular piece of foil is 7 ¼ square inches. Its length is 3 ½ inches. What is the width of the foil?

Answers

Answer:

Approximately 2.07 square inches

Step-by-step explanation:

Area of a rectangle: Length × width

Area: 7.25 square inches

Length: 3.5 square inches

Width = 7.25 ÷ 3.5

          ≈2.07

Create an equation modeling the scenario. Use the equation to solve for the missing number. In your final answer, include the equation and all necessary calculations. Twice the sum of a number and seven is three times the number.

Answers

Answer:

2(n+7)=3n

Step-by-step explanation:

"A number" is unknown so just create a variable in this case I made it "n."

We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.

2 (n+7)=3n Hopefully this helps !!!

Answers

Answer: x = 4, y = 0
Steps: multiplying the first equation by 2, we get 2x-2y=8. Adding that to the second equation we get 3x = 12. Dividing both sides by 3, we get x = 4. Substituting it into x-y = 4, we get y = 0.

Solve: y = x + 2
y + 1 = - 4x
On paper

Answers

Answer:

(x ,y)= (1/3, -4/3)

Step-by-step explanation:

simplify

y = -4x

x + 2y + 1 = -4x

multiply both sides

4x + y = 0

5 x + 2y = -1

eliminate one variable

-8x - 2y = 0

5x + 2y = -1

divide

-3x = -1

x = 1/3

possible solution

y= -4/3

check the solution

(x, y) = (1/3, -4/3)

simplify

-4/3 = 1/3 + 2 x (-4/3) + 1 = -4 x 1/3

place in order

-4/3 = -4/3 = -4/3

Step-by-step explanation:

Ok, a function means that the domain (x) does not repeat... so if you look at all of the first numbers in the ordered pairs or x and none of them are repeating in the set that is your answer. For this the answer would be 1 and not 2 because x has a exponent making it 2 x and not 3 because there is 2 10s. Let me know if this helps and you have any other questions.
