Twice the sum of x and 6 is at most 52. What is the greatest value of x that satisfies the inequality that represents this situa
Shalnov [3]
Our inequality looks like this:
2(x+6)≤52
Using the Distributive Property, we have
2*x + 2*6 ≤52
2x+12≤52
Cancel the 12 by subtracting from both sides:
2x+12-12≤52-12
2x≤40
Divide both sides by 2:
2x/2 ≤ 40/2
x≤20
x cannot be any more than 20 to satisfy this inequality.

Consider the equations 4(x-3)=16 and 4x-3=16 do they have the same solution? Why or why not ?
Sladkaya [172]

Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation  4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16  there is no variable to multiply with the LHS equation

Solution:

4 (x-3)=16

4x - 12 = 16

4x = 16 + 12

4x = 28

x = 7


4x - 3 = 16

4x = 16 + 3

4x = 19

x = 19/4

x = 4.75
