Answer:
Claire = 30 stickers
Josh = 60 stickers
Ann = 67 stickers
Step-by-step explanation:
Let
Claire stickers= x
Josh = 2x
Ann= 2x + 7
Total stickers = 157
Total stickers = Claire stickers + Josh stickers + Ann stickers
157 = x + (2x) + (2x+7)
157 = x + 2x + 2x + 7
157 = 5x + 7
Subtract 7 from both sides
157 - 7 = 5x + 7 - 7
150 = 5x
Divide both sides by 5
150/5 = x
30 = x
x = 30
Claire stickers= x
=30 stickers
Josh = 2x
= 2(30)
= 60 stickers
Ann= 2x + 7
= 2(30) + 7
= 60 + 7
= 67 stickers
Claire = 30 stickers
Josh = 60 stickers
Ann = 67 stickers
The answer you have selected is correct
Answer:
6.667%
Step-by-step explanation:
Given that:
Actual measurement = 7.5 mm
Measured value = 7 mm
Percentage error :
Error / (Actual measurement.) * 100%
(Actual measurement - measured value)
Error = 7.5 - 7 = 0.5 mm
Percentage error = (0.5 / 7.5) * 100%
Percentage error = 0.0666666 * 100%
= 6.667%
