Answer:
x = 7
Step-by-step explanation:
Add 3x to both sides of the equation.
2x = 6+8
Divide both sides by 2.
x = 7
Answer:
C. 5
Step-by-step explanation:
3x – 7 > – 1
Add 7 to each side
3x – 7+7 > – 1+7
3x> 6
Divide each side by 3
3x/3 >6/3
x >2
X must be greater than 2
Answer:
x = 31 and x = 15
Step-by-step explanation:
(a)
(3x + 31) and (2x - 6) are a linear pair and sum to 180° , then
3x + 31 + 2x - 6 = 180
5x + 25 = 180 ( subtract 25 from both sides )
5x = 155 ( divide both sides by 5 )
x = 31
(b)
3x and (4x - 15) form a right angle and sum to 90° , then
3x + 4x - 15 = 90
7x - 15 = 90 ( add 15 to both sides )
7x = 105 ( divide both sides by 7 )
x = 15
Dividing the number of balloon animal per the time he takes to make them you get an average of how many animals per minute Fred the clown can make.
20/15=1,3 animals per minute
Since 0,3 is not a complete animal, the correct answer would be "Fred the clown can make 1 animal in 1 minute"
