Luis spends 2 hours out everyday. he spends 45 minutes lifting weights. 42 minutes doing cardio, and the rest of the time he spends on his boxing training. what percentage of time does he spend boxing?

Step-by-step explanation:

2 hours (convert it to minutes) = 2 x 60 = 120 mins

time spent on cardio and lifting weights = 45 + 42 = 87 mins

time spent on boxing = 120 mins - 87 mins = 33 mins.

percentage he spent on boxing = 33\120 x 100% = 27.5%

Simplify both sides of the equation

(20)(4)= 4(5x+1)

Simplify

80 = 20x+4

Flip the equation

20x+4 = 80

Subtract 4 from both sides

20x+4-4=80-4

20x= 76

divide both sides by 20

20x/20= 76/20

x= 3.8

There is only one solution in this equation
