Answer: Commutative.

Step-by-step explanation: The Commutative Property of addition states that changing the order of the addends does not change the sum. Here that is proven as -5 and 2 are switched and the equal sign remains, meaning the sun will not change like the property says.

Answer: 9.9 yards

Step-by-step explanation: Since we know that the legs of the right triangle both measure 7 yards, we can use the Pythagorean theorem to find the length of the hypotenuse, which is the longest side of the right triangle.

According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the legs. In this case, we have:

c^2 = 7^2 + 7^2 c^2 = 49 + 49 c^2 = 98

To find the length of the hypotenuse, we need to take the square root of both sides of the equation:

c = √98

Using a calculator, we can find that √98 is approximately 9.9. Therefore, the length of the hypotenuse is approximately 9.9 yards.

The answer is C. 9.9 yards.

Answer: -2

Step-by-step explanation:

Because it is in the negative and has an open hole. sorry if it wrong

Answer: A, and E

Step-by-step explanation:

x is anything less than -200. Because youre in the negatives you have to think about it backwards. -120 is closer to 0 same with 102 and because x isnt less than or equal to -200, its not an answer either

Answer:{x|x<-200}

Step-by-step explanation:

write the inequality in set builder notation as the set of the all real numbers x such that x is less than -200

Answer:

Let me explain. :)

Step-by-step explanation:

Step 1:

We know that Gherell has 75 marks. Delia has 5 marks less than Gherell, so  we do 75-5 which is 70.

Step 2:

To find out Josiah's mark, we must find 20% of 70. Now, I am not sure if you learned how to find the percents and the amount of decrease, but if you calculate, it is 14. Then you do 70-14 because 14 is how many marks he lost, and that is 54.

Step 3:

Subtract 4 from 54 to get 50 marks.

Step 4:

Shevonne's marks are the average of both Josiah and Liam's mark, so we must find the average. The average is calculated by adding both Josiah and Liam's mark, and divide it by the number of people. [tex]\frac{Josiah+Liam}{2} = \frac{54+50}{2}[/tex]

Then, you get 104/2 which is 52. Shevonne has 10 more marks than the average, so you would add 10 to 52 which is 62.

There we have it! Hope it helped. :D

Answer:

Step-by-step explanation:

To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:

w/7 > 38

w > 7 x 38

w > 266

This means that any value of w greater than 266 satisfies the inequality.

We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:

<--o======(266)---------------->

This represents the solution set of w/7 > 38.

I think it's angles 5 and 2, angle 3 and 6, angles 4 and 1.

Answer: 188,736

Step-by-step explanation:

The original amount is 192,000. Every year, the population decreases by 1.7%, which means that the population is 98.3% of last year's.

0.983 * 192,000 = 188,736

Answer:

(6,4)

(-3,2)

(4,5)

Answer: y=-7

Step-by-step explanation:

solve 5x+2y =-4 for x

Add -2y to both sides

divide both sides by five
substitue -2/5y +-4/5 for x in 3X +10 Y equals -64

44/5 + -12/5 equals -64

Simply both sides

add 12/5 to both sides

Divided by 44/5
y= -7

Answer:

Hence The Value of Y=-2 at the intersecting point

Step-by-step explanation:

Given the equation

5x+2y=-4 and 3x+10y=-64

are intersected at X=2 to find the value of y

solution the equation 5x+2y=-4 and 3x+10y=-64

are intersect at x=2 means x=2 satisfied both equations so x=2 put in the

1st equation

5 x 2+2y=-4

2y=-4 -1 0= -14

y= -7

Answer:

Slope : -1/3

Answer:

x ≥ -53

Step-by-step explanation:

The solid dot means that -53 is included in the solution.

The arrow pointing right means all numbers greater than -53 are also included.

The graph means -53 and all numbers greater than -53.

Answer: x ≥ -53

Answer:

38,400,000 cubic feet.

Step-by-step explanation:

To find the volume of a pyramid, you can use the formula:

V = (1/3) * base area * height

In this case, the base is a square with sides of 600 feet, so its area is:

base area = 600 * 600 = 360,000 square feet

The height of the pyramid is given as 321 feet.

Now we can plug in the values into the formula:

V = (1/3) * 360,000 * 321

V = 38,400,000 cubic feet

Therefore, the volume of the Pyramid Arena in Memphis, Tennessee, is approximately 38,400,000 cubic feet.

Answer:

Step-by-step explanation:

Given the system of equations,

[tex]y=2x-3\\y=-x+3[/tex]

We can substitute one equations into another since both equations solve for y. I will use the second equation for this example.

Step 1: Substitute

[tex]-x+3=2x-3[/tex]

Step 2: Simplify

[tex]6=3x\\x=2[/tex]

Now, we can easily substitute our x value into one of the equations.

Step 3: Substitute.. again

[tex]y=-2+3\\y=1[/tex]

Solution: [tex](2,1)[/tex]
