answer this question I will make you as a Brainlist​

Answer 1

Answer:

(i) 15x = 27 + 6x

=> 15x - 6x = 27

=> 9x = 27

=> x = 27/9

=> x = 3 <=

(ii) first 4 counting numbers :- 1,2,3&4

Mean = sum of observations / Number of observations

=> Mean = 1+2+3+4/4

=> 10/4 => 5/2

=> [ 2.5 ] <=

(iii) 2.331 × 100

=> 233.1 <=

(iv) successor of - 1 => 0

(v) 87 +x = 180 [ supplementary angles ]

=> x = 180 - 87

=> x = 93° <=

(vi) exponent = 3

base = 5

hope it helps you

Answer 2

Step-by-step explanation:

i) 15x=27+6x

+15x-6x=+27

+9x=+27

x=3

ii) mean of first four counting numbers is :

10/4+2.5

iii) 2.331 × 100 = 233.1

iv) successor of -1 = -2

v) supplement of 87 degree = 93

vi) exponent = 3

and

base = 5
