Kira's time exercising every day can be represented as t ≥ 40 because she exercises for 40 minutes or more.
<h3>How can this situation be represented?</h3>
This situation can be represented with an inequality. An inequality is an expression that is used to represent variables. This type of expression uses symbols such as >, < or ≥ to represent different variable values.
<h3>What inequality is represented in this situation?</h3>
- The expression is: t ≥ 40
The inequality represented in this situation implies that Kira exercises is equal or more time than 40 minutes every day.

Answer:
The y-coordinates of the solutions to the system and the zeros of the equation are not equal
Step-by-step explanation:
let "a number" = x
a number is divided by 3 => x/3
14 is added to the quotient => (x/3) + 14
The result is 33 => " = 33"
Solve for x
(x/3) + 14 = 33
Isolate the x. Note the equal sign. What you do to one side you do the other.
Subtract 14 from both sides
(x/3) + 14 (-14) = 33 (-14)
x/3 = 19
Isolate the x. Multiply 3 to both sides
x/3(3) = 19(3)
x = 19(3)
x = 57
57 is your original number
hope this helps
378
x 6
six is your base number.. then you do 6x8 which is 48 you will leave the 8 under the ones column and carry the 4 above the seven then you do 7x6 plus the 4.
I think that's how i learned it
