Which Property of Equality should be used first to solve the equation p/7 - 5 = -3 for pAddition Property of Equality

Subtraction Property of Equality

Multiplication Property of Equality

Division Property of Equality

Answers

Answer 1

Answer: Well, let's solve it and see which properties we're using:

p/7 - 5 = -3

Add 5 to each side. (Addition property.)

p/7 = 2

Multiply each side by 7. (Multiplication property.)

p = 14

A 12-foot flagpole casts a nine-foot shadow. What is the measure from the top of the shadow to the top of the flag pole?

Answers

Here is the answer OwO:

A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.

Here is the explanation/work OwO:

Switch sides.

c^2=12^2+9^2

12^2=144

c^2=144+9^2

9^2=81

c^2=144+81

Add the numbers: 144 + 81 = 225

c^2=225

For x^2 = f(a) the solution is √f(a)

c = 15

Therefore, your answer will be 15.

Step-by-step explanation:

Shivani is making greeting cards, which she will sell by the box at an arts fair. She paid $20 for a booth at the fair, and the materials for each box of cards cost $5. She will sell the cards for $7 per box of cards. At some point, she will sell enough cards so that her sales cover her expenditures. How many cards will that take?

Answers

Answer:

10 cards

Step-by-step explanation:

So to do this problem, you can make an equation where x is the number of cards sold, which would be:

7x - 20 - 5x = 0

This is because she makes $7 for every card she sells (so 7x), she paid $20 for the booth (so -20), it costs her $5 to make every card (so -5x), and you want to see how many cards it will take for her to cover everything she spent (so it would equal 0).

Then, solving:

$7x-20-5x=0$
