Answer:

First, you must know what 5^2 and 5^3 are equal to.

5^2 = 5 * 5 = 25

5^3 = 5 * 5 * 5 = 125

If x^2 is equal to 25, x = 5. If x^2 is greater than 25, x > 5. If x^2 is less than 25, then x < 5.

If x^3 is equal to 125, x = 5. If x^3 is greater than 125, x > 5. If x^3 is less than 125, then x < 5.

x^3 = 15; x < 5

x^2 = 25; x = 5

x^3 = 36; x < 5

x^2 = 49; x < 5

x^2 = 50; x > 5

x^3 = 125; x = 5

Wich is greater 500 seconds or 8 minutes

Answers

500 seconds is greater. Since there are 60 seconds in one minute you would multiply 60 and 8. 
60x8= 480
500 seconds because 8 sixty times is 480 so 500 is greater

Which out of these numbers has the same absolute value as one another and please help I don't really understand absolute value

Answers

Answer:

Step-by-step explanation:Absolute value is a number's distance away from zero. For example, on a number line, -9 is 9 spaces away from zero. So, the absolut value is 9. Similarly, the number 9 is also 9 spaces from zero, so the absolute value would be 9. 9 and -9 both have an absolute value of 9. I hope this is helpful!

The second of 2 numbers is 5 more than twice the first. Their sum is 29. Find the numbers

Answers

Call the numbers x and y. Let y be the larger number.
The second of 2 numbers is 5 more than twice the first is y = 2x+5
Their sum is 29 is x+y=29.
Substitute 2x+5 for y in the second equation.x+2x+5=29
3x=24
x=8
y = 2(8) + 5 = 21
Hope the solution helped.
Briemode!:)
so call the numbers x and z
first number=x
second number=z
second of 2 numbers (z) is = 5 more than (5+) twice the first (2x)
z=5+2x
their sum is 29
x+z=29
subsisute 5+2x for z in equation
x+5+2x=29
3x+5=29
subtract 5
3x=24
divide bboth sides by 3
x=8
subsitute 8 for x
z=5+2(8)
z=5+16
z=21

numbers are 8 and 21
