Step-by-step explanation:
total = ¼(sale $ + marathon $)
253.75 = 1/4(184.6 + m)
1,015 = 184.6 + m
m = $830.40
5x+2=47 subtract 2 from both sides
5x=45 divide both sides by 5
x=9
Answer:
1st option
Step-by-step explanation:
Just did it
A 360 degrees counter-clockwise rotation will bring the triangle at the same place.
So, divide 1980 by 360 and find the remainder.
On dividing, we can find that
1980 = 5(360) + 180
A 1800 degrees rotation will rotate the triangle 5 times and will bring it in the same place.
A further 180 degrees rotation will rotate the triangle to two quadrants back and will bring it in the first quadrant.
W = words per minute = 80
t = time in minutes = 30
The total number of words per 30 minutes is w*t = 80*30 = 2400 words
