Step-by-step explanation:
Answer:
The answer is 75 and 85.
Step-by-step explanation:
If the instrument measures in units of 10, then the measurement could be 5 units on either side of 80 (80 − 5 = 75, 80 + 5 = 85). Any value between 75 and 85 would be measured as 80.
(4/117) = (x/118)
Solve for x BOOM
For the 3rd sum
Subtract
(10^5 - 10^2) = 10^3
And for the 4th sum
a) 2(2b+g)
b) b = - 2g/4
c). g = - 4b/2
