Which expression can be used to determine the total weight of a box that by itself weighs 0.5 kilogram and contains t trophies that weigh 1.6 kilograms each? a) 1.6t+0.5 b) 1.5t c) 0.5t+1.6 d) 0.5-1.6t

Option A) 1.6t+0.5

Step-by-step explanation:

Let

t ----> the number of trophies

we know that

To determine the total weight of the box, multiply the number of trophies by the weight of each trophy and add the weight of the empty box.

The linear equation that represent this problem is

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

40 x 50 = 2000
