The formula for circumference is 2πr.
C = 2(3.14)(119.3)
C = 749.204
Nearest tenth would be 749.20 mm
Our missing number we are solving for is X.
We are told x will equal 2x (number doubled) plus -16.
x = 2x + -16 We want to move the smaller variable to the right to sit with the larger one and move the -16 to the left by subtracting it from both sides. Remember that subtracting a negative is the same as adding it. So essentially we add 16 to both sides.
16 = 2x - x Combine the variables
16 = x or x = 16
I chose to put the variable on the left in this problem to avoid having a -x on the left side. It doesn't matter which side the variable is on to solve, but when you state it - we usually say x = 16.
The answer would be x= 5 and y= 0

Answer: 349.99 Newton must be exerted on the small piston
Step-by-step explanation:
In changing a tire a hydraulic jack lift 7468 newtons on its large piston which has an area of 28.27 cm squared. Pressure is expressed as force/area
Pressure exerted and transmitted to the smaller piston is
7468/28.27 = 264.14N/cm²
If the small piston has an area of 1.325 cm squared, the force that would be exerted on the smaller piston is
Force = pressure × area
= 264.14 × 1.325 = 349.99 Newton
