Mathematics Middle School

Can you please answer, my parents are going to be so mad if I can't correct by like the afternoon right now its about 1:31.Anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:

Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???

A store paid $450 for a tablet and marked up the price to sell for $500. What is the percent increase?

please answer quickly!

Answers

Answer:

11.1111%

Step-by-step explanation:

markup = profit/cost * 100

Answer: 12% increase

Explanation: if you use the formula in the pic I’ve provided below, you can find the increase by first subtracting the old value (450) by the the new value which would be (500-450). Then, you divide the answer you got (50) by the old value once again, and you would get (50/450 = 0.11 *rounded) and 0.11 as a percent is 11%, so the percent increase it 11%.

Grimaldi's Pizza has a personal pan pizza with a diameter of 6 inches. Breinor orders two personal pan pizzas. What is the area of the two pizzas?

Answers

Area of the two pizzas is 56.54 sq in

To find the area of a circle, you simply to radius squared, then multiply that by pi, so the diameter is 6 and the radius is half that so the radius is 3. Then plug it in the area of a circle so the area of one pizza is 28.27 Since we are trying to find the area of 2 pizzas, we just add 28.27 to 28.27 since they are both large pizzas and when you add them (28.27+28.27), they equal 56.54

what is the solution to -6x+y=-34 and
x+y=-1

Answers

They’re both 0 I think, I used photomath

Answer:

1. x = 1/6(y) + 17/3

2. x=−y−1

Step-by-step explanation:

1. Let's solve for x.

−6x+y=−34

Step 1: Add -y to both sides.

−6x+y+−y=−34+−y

−6x=−y−34

Step 2: Divide both sides by -6.

−6x/−6=−y−34/−6

x=1/6y+17/3

2. Let's solve for x.

x+y=−1

Step 1: Add -y to both sides.

x+y+−y=−1+−y

x=−y−1
