Multiply by 6 and simplify
.. x = 6*12/9 = 72/9 = 8
x = 8
Step-by-step explanation:
To do this, we will substitute the x values to their corresponding equations,
1)

Given 2x + 15 = 19
Calculated 2x + 15 = 19
Given = Calculated, this solution is correct.
2)

Given 3 + x + 2 - x = 16
Calculated 3 + x + 2 - x = 5
Given not equal to calculated, this solution is incorrect.
3)

Given (x+2)/5 = 2
Calculated (x+2)/5 = 2
Given = Calculated, this solution is correct.
4)


Given 2x - 8 = 6
Calculated 2x - 8 = 6
Given = Calculated, this solution is correct.
5)


Given 1/3x + 5 = 14
Calculated 1/3x + 5 = 11
Given not equal to Calculated, this solution is not correct.
Therefore the Correct solutions are 1,3 and 4.
Answer:
6.75 inches each
Step-by-step explanation:
128 less 2 inches for the cuttingblade
5 x 15.75 = 78.75
126 - 78.75 =47.25
47.25/7 = 6.75
Step 1) you should put 8 to fill in the blacks
step2) It is 300
step3)167.467
