2) 480
3) 144
4) 2m > 84 $
4m > 168 $
10m> 420 $
13m> 546$
Step-by-step explanation:
1) 582 in 30 mins ... so in third the time 582÷3 = 194
2)120 tools in 5 hours , so 120 ÷ 5 = 24 tools per hour > so 24 × 20 = 480
3) 1kg is for 18$ ... so 8kg will be 8 × 18 = 144
4) 5meters cost 210$ , one meter costs 210÷5 =42
now multiply , 2×42 = 84 , 4×42 = 168 , 10×42= 420 , 13×42 = 546

Answer:
-35
Step-by-step explanation:
-15 -20
= -35
But if you want the positive difference, it would be 35
The answer is 6.35. Because you put in 254 / 40 and it says 6.35.
What you are asking is x + 30 ÷ 11 = 1
x + 30 ÷ 11 = 1
Simplify
x + 30/11 = 1
Subtract 30/11 from each side
x + 30/11 - 30/11 = 1 - 30/11
x = -19/11
