Solve for x. −4≤11−3x Enter your answer as an inequality in the box.
Mamont248 [21]

Answer:

x\leq 5

Step-by-step explanation:

  • the given expression is : −4≤11−3x
  • we use following operations to solve the inequality:
  • by adding 4 on both sides, the inequality will become :

-4+4 ≤ 11-3x +4

0 ≤ 15 -3x

  • adding 3x on both sides, the inequality will become:

3x ≤ 15

  • dividing both the sides of the inequality by 3, the inequality will become:

3x/3 ≤ 15/3

x ≤ 5                  ( since, 15/3 = 5)

  • therefore the solution for x as an inequality will be x ≤ 5

10. The sum of two numbers is 102. One number is three less than twice the other.
netineya [11]

Answer:

(2n -3) + n = 102

2n - 3 + n = 102

3n - 3 = 102

3n = 105

n = 35 (the first number)

SO...

The other number is (2 x 35) - 3 =

                                           70 - 3 = 67 (the second number)

The numbers are 35 and 67.

35 + 67 = 102 CHECK!
