sorry i have no idea about the last question

but hope it will help you ☺️

Answer 2

Step-by-step explanation:

41)180°-75°=105°

42)variable and solution or root

43)3x+4=19

= 3x=19-4

=>3x=15

=>x=15/3

therefore x=5

44)9/5x=18/5

=>x=(18/5)×(5/9)

=>x=18/9

= x=2

45)heighest value=21

Lowest value=4

Range =Heighest value-Lowest value

Range=21-4=17

46)median=9

47)mean =sum of all observations/nom of all observations

=>M=(2+3+5+7+11+13)/6

=>M=41/6

=>M=6.71

48)-157×-19+157

=>157×19+157

=>157(19+1)

=>157×20

=>3140

49)-62+25=-37

-37+25=-12

-12+25=13

the next term is 13

50)let the other be X

-70+X=280

=>X=280+70

=>X=350

The other integer is 350
