Answer:

Final lesson= 75 mins.

Step-by-step explanation:

Ok so I see where you got the 27 from because my initial thought was to multiply the 4 and 1/2 times 6 which would equal 27, but it is not asking for that.

They are saying that all six classes combined last for 4 and 1/2 hours, and that each class is the same amout of time. Which means we would have to divide 4 and 1/2 by 6 to find the answer that we are looking for. 4.5 (the decimal version of 4 and 1/2) divided by 6 equals .75. If you use the fraction and divide you would get 3/4 which is the same thing as .75.

This means each lesson is 75 minutes.

Step 2: Add 1 to both sides.

4x−1+1=3+1

4x=4

Step 3: Divide both sides by 4.

Answer:

∠4 and ∠3

∠4 and ∠5

∠3 and ∠6

Step-by-step explanation:

A pair of angles is said to be supplementary when the 2 angles add up to give 180°.

Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.

Thus, since m< 3 is given as 90°, m<4 = 90°.

m<4 + m<3 = 180°.

Therefore, <4 and <3 are supplementary.

<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
