4 0

Answer:

X=4.2

Step-by-step explanation:

Simplifying 8x + -4 = 3x + 17 Reorder the terms: -4 + 8x = 3x + 17 Reorder the terms: -4 + 8x = 17 + 3x Solving -4 + 8x = 17 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -4 + 8x + -3x = 17 + 3x + -3x Combine like terms: 8x + -3x = 5x -4 + 5x = 17 + 3x + -3x Combine like terms: 3x + -3x = 0 -4 + 5x = 17 + 0 -4 + 5x = 17 Add '4' to each side of the equation. -4 + 4 + 5x = 17 + 4 Combine like terms: -4 + 4 = 0 0 + 5x = 17 + 4 5x = 17 + 4 Combine like terms: 17 + 4 = 21 5x = 21 Divide each side by '5'. x = 4.2 Simplifying x = 4.2

Hope this helps :)

Write a problem situation for this inequality 72-12a<24
Morgarella [4.7K]

Answer:

Subtracted 12 times a number from 72 is less than 24.

Step by step solution

Given inequality is 72-12a

We need to write in word.  

12a means 12 times a number “a”

72-12a means subtract 12a from 72.

72-12a<24 means result is less than 24.  

Inequality shows “Subtracted 12 times a number from 72 is less than 24”

If we solve for number “a”

-12a<24-72

-12a<-24

a>2

All the number greater than 2 satisfy the given inequality.

Solve equation (n-1)(n+6)(n+5)=0
Vika [28.1K]
Answer:
1, -6 and -5 

Explanation:
To solve the equation means to get the values of n which satisfy the given equation.
The equation given is:
(n-1) (n+6) (n+5) = 0
This equation will be true if any of the terms (brackets) is equal to zero.
This means that:
either n-1 = 0 .............> n = 1
or n + 6 = 0 ................> n = -6
or n + 5 = 0 ................> n = -5

Hope this helps :)
