Answer:

z=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(z+6)−2=9z

(5)(z)+(5)(6)+−2=9z(Distribute)

5z+30+−2=9z

(5z)+(30+−2)=9z(Combine Like Terms)

5z+28=9z

Step 2: Subtract 9z from both sides.

5z+28−9z=9z−9z

−4z+28=0

Step 3: Subtract 28 from both sides.

−4z+28−28=0−28

−4z=−28

Step 4: Divide both sides by -4.

−4z/−4=−28/−4

z=7

Distribute, so 5z+28+9z, then subtract 5z, and you get 4z=28. Divide by 4 so x=7

Convert 28.7251° to degrees, minutes, and seconds. Round to the nearest second.
Leni [432]

28.7251 =

 28 degrees

 then take the decimal and multiply by 60 to get the minutes

 so 0.7251 *60 = 43.506, use the whole number (43)

 so now you have 28 degrees, 43 minutes

 now take the remaining decimal ( 0.506) and multiply by 60

0.506*60= 30.36

 when you have a decimal left over for the seconds, keep that as is.

 so you now have 28 degrees, 43 minutes and 30.36 seconds

 use ' for minutes and " for seconds

28 degrees 43' 30.36"
