Let t = 5.

What is the value of 5t – 5?

Answer: If t=5, you just need to substitute 5 for t in the equation and solve, so

5(5) - 5
25 - 5 = 20

Hope this helped :)

Find three consecutive integers whose sum is 60.

Answers

Answer: 19, 20, and 21

Step-by-step explanation: This problem states that the sum of 3 consecutive integers is 60 and it asks us to find the integers.

Three consecutive integers can be represented as followed.

X ⇒ first integer

X + 1 ⇒ second integer

X + 2 ⇒ third integer

Since the sum of our 3 consecutive integers is 60, we can set up an equation.

X + X + 1 + X + 2 = 60

3x + 3 = 60

-3 -3

3x = 57

÷ 3 ÷ 3

X = 19

X + 1 = 20

X + 2 = 21

Therefore, our three consecutive integers are 19, 20, and 21.

60 = x + x + 1 + x + 2

60 = 3x + 3

-3

57 = 3x

19 = x

The 3 integers are: 19, 20, and 21.

This math has letters.

Answers

Maybe is an equation, they are like "2x-5=34"

If it so, then the way to resolve it would be adding the five (if the symbol is a minus) in both sides ( under the five and under the 34, then eliminate the "-5" and is going to be "2x=38") Then divide 2 in both sides (2/2 and 38/2) and is going to be (x=19)

BUT if it's not the type of question you are referring about then idk how to help you because i don't have any details (?)
