Answer:
the equivalent expression is 1.1(1.3)^4 ×(1.3)^x
2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-1x = -4
x = 4
y = 4 - 1
y = 3
4.876 < 4.879
the first three digits are the same, however the last digit, which is the fourth digit from both sides are 6 and 9
6 is less than 9 therefore that determines the whole value of 4.876 to be less than 4.879
Answer:
(a) 0.5km or 500m
(b) 100m
Step-by-step explanation:
(a) 1 hour = 60 minutes
60 minutes = 30km
5 minutes = 30 ÷ 60
= 0.5km = 500m
(b) 1 minute = 500m ÷ 5
= 100m

x = -1 y = -7
x = 0 y = 0
x = 1 y = 7</span>
