Between the time iko woke up and lunchtime, the temperature rose by 11. Then by the time he went to bed, the temperature dropped by 14.
Write an addition expression for the temperature relative to when iko woke up.
Draw a model using integer chips and circle the zero pairs.

x+11-14

Step-by-step explanation:

The temperature rose by 11 and fell by 14 so you add 11 and subtract 14 from the original number.

T + 11 - 14 = T - 3

Step-by-step explanation:

Let's call T to the initial temperature.

Between the time iko woke up and lunchtime, the temperature rose by 11. So, the temperature at that time was: T + 11

Then by the time he went to bed, the temperature dropped by 14. So, we have to subtract 14 to the previous temperature, that is, T + 11 - 14 = T - 3

In the picture attached, the model using integer chips is shown. The zero pairs are shown in rectangles.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
