Answer:
u=2
Step-by-step explanation:
8u-21 = 2u-9
+21 +21
8u= 2u + 12
-2u -2u
6u= 12
divide by 6, u=2 !!
Answer:1:b i think
2: 125
Step-by-step explanation:
Answer:
a = 93°, b = 120°, c = 150°
Step-by-step explanation:
b + 36 = 78 × 2 => b + 36 = 156 => b = 120°
87 × 2 - b = the minor arc between a and 78
=> 174 - 120 = 54
54 + b + 36 + c = 360
=> 54 + 120 + 36 + c = 360
=> c = 150°
(c + 36) ÷ 2 = a
=> (150 + 36) ÷ 2 = a
=> a = 93°
A scale measures weight to the nearest 0.1 pounds
we have to find the most appropriate way to report weigh using this scale
we are given with a few no. of weighs
now lets discuss about weight one by one
200 pounds-it is looking a rounded figure
152 pounds-it is again looking a rounded figure
152.127-it is .not possible because its nearest measure is only 0.1
152.2-it is looking most appropriate as it has one decimal and the given weight scale is also correct to one decimal place
