Answer:
t=-3.7
Step-by-step explanation:
5 (t+3)=-3.5
solving the bracket we have;
5t+15=-3.5
collect like terms
5t=-3.5-15
5t=-18.5
divide both sides by 5;
t=-3.7
The value of t in the given algebraic expression is; t = -2.3
We are given the equation;
5(t + 3) = 3.5
Using distributive property on the left hand side, we have;
5t + (5 × 3) = 3.5
5t + 15 = 3.5
Using subtractive property of equality, subtract 15 from both sides to get;
5t + 15 - 15 = 3.5 - 15
5t = -11.5
Divide both sides by 5 to get;
5t/5 = -11.5/5
t = -2.3
