Question

T=s+.50 T=0.25s+1.70 In the equation above t and a represent the weight in tons of a sedan and of a truck, respectively. What is the weight of a sedan in tons

Answer 1

Answer :

The weight of a sedans in tons is 2.1 tons.

Step-by-step explanation:

Given : Equations $T=s+0.50$ and $T=0.25s+1.70$ where T and s represents the weight in tons of a sedan and of a truck, respectively.

To find : What is the weight of a sedan in tons ?

Solution :

Solving equations,

$T=s+0.50$ ......(1)

$T=0.25s+1.70$  .....(2)

As LHS is equate we equate RHS,

$s+0.50=0.25s+1.70$

$s-0.25s=1.70-0.50$

$0.75s=1.2$

$s=\frac{1.2}{0.75}$

$s=1.6$

Substitute in equation (1),

$T=1.6+0.50$

$T=2.1$

Therefore, the weight of a sedans in tons is 2.1 tons.
