At practice, Diego does twice as many push-ups as Noah, and also 40 jumping jacks. He does 62 exercises in total. The equation: 2x + 40 = 62 describes this situation. What does the variable x represent?

Step-by-step explanation:

x = number of pushups he did

the number of pushups done by Noah

Step-by-step explanation:

if Noah did x amount of pushups then Diego did twice as many, which is 2x therefore in this equation x represents the number of pushups done by Noah

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
