Answer:

t = 7

Step-by-step explanation:

Equation

7t + 4 = 102 - 7t

Solution

7t + 4 = 102 - 7t                       Add 7t to both sides

7t + 7t +4 = 102 - 7t  + 7t         Combine

14t + 4 = 102                            Subtract 4 from both sides

14t + 4 - 4 = 102 - 4

14t =98                                Divide by 14

14t / 14 =98/14

t =7

PLS PLS HELP! I need the answer ASAP
Nat2105 [25]

Answer:

E

Step-by-step explanation:

-x +6 ≥  -3x - 4

Add 3x to both sides

-x + 3x + 6 ≥ -4

Combine like terms

2x + 6 ≥ -4

Subtract 6 from both side

2x ≥ -4 - 6

2x≥ -10

Divide both sides by 2

x ≥ -10/2

x ≥ -5
