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.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
