(11 +30 - 5) - (1-5)​

Answer: 72km/hr

Explanation:

First let’s find the distance:

d = 42 x 4 = 168

Use the formula to find the average speed: v = d/t

V = 168/2 1/3hr (1/3hr = 20mins)

V = 168 divide by 7/3 (2 1/3 = 7/3)

V = 168 x 3/7

V = 72

(8 - 3i)(2 - 7i)=
16 x -56i - 6i + 21i^2
16 x -50i - 21

6x + 5y-15> = 0
 For this case what you should do is to graph the following straight line:
 6x + 5y-15 = 0
 Then, the solution will be the shaded region that satisfies the following inequality:
 6x + 5y-15> = 0
 In the shaded region you will find all the solution points.

I hope this helps you



6x-20/3x-5= -1


18x-20x/3= 4


-2x=12


x= -6

So...lets first think about what the word means to actually determine its synonyms. 

Subvert :- To overthrow, or take down 

Since this refers to an action that is upsetting, that would best fit the synonym.

Answer; To upset
