Cole’s age is 3 years less than his sister tina’s age, t. if cole is 18, which equation represents this situation, and how old is tina?
a. the equation that represents this situation is t − 3 = 18. tina is 21.
b. the equation that represents this situation is t + 3 = 18. tina is 15.
c. the equation that represents this situation is 3 − t = 18. tina is 21.
d. the equation that represents this situation is -3 − t = 18. tina is 15.

The Answer Is A

Step-by-step explanation:

If cole is 18 and he is 3 years younger then tina then tina is 21 because if you add 18 and 3 you get 21 and to show the equation its t - 3 = 18.

Option A is correct answer.

Step-by-step explanation:

Here age of Tina is given to be t

Cole's age = 3 year less than Tina's age ,that is t-3

which is given to be 18

therefore equating both we get

t-3=18

adding 3 both sides in order to solve for t ,we get

t = 18+3

t= 21 years

therefore  Equation to find the age of Tina is t-3 =18 and

the age of Tina is 21 years.

Therefore option A is correct answer.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
