For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'
cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200
The coordinate of the midpoint:
x m = ( x 1 + x 2 ) / 2
x 1 = - 2, x 2 = 12
x m = ( - 2 + 12 ) / 2 = 10 / 2 = 5
Answer:
The coordinate of the midpoint of a line segment PB is 5.
Answer:he will use 45 minutes to burn 540 calories . he spend a total of 50 minutes ie including 5 minutes of rest.
Step-by-step explanation: 1 minute burns 12 calories
