(1) a = 16 , (2) x =4 , (3) x = 0 ,(4) n =-20 , (5) r = 20 and (6) x = -11
Step-by-step explanation:
(1) 6 = a/4 + 2
4 = a/4 (It is because when you bring +2 over to the left it will become 6 -2)
a = 16 (it is because of the fraction, so when you bring the divisor over it becomes x 4)
The following questions same as qns 1 too
(2) -6 + x/4 = -5
x/4 = 1
x = 4
(3) 9x -7 = -7
9x = 0
x = 0
(4) 0 = 4 + n/5
-4 = n/5
n = -20
(5) -4 = r/20 -5
1 = r/20
20 = r
(6) -1 = 5 + x/6
-6 = 5 + x
-11 = x
3. is correct because you divide the 5.8x10^6 ( what is 5 800 000 ) by 60 and then you just move the comma to the right making the number smaller so you get 9.67x10^4
The 3 number should be: 0, 1 and -1.
