9x^3-74x+28
X
Step-by-step explanation:
USED PHOTOMATH BTW. DUNNO IF ITS RIGHT OR WRONG.
First find 60% of 145 =
60% of 45 equals 87.
Now subtract 87 from 145.
145 - 87 = 58
So there were 58 girls.
The answer to the solution of the equation 5x+2y=-1 is 1,-3)
The resulting number would be 120
Multiply the speed of the train by how many hours it travels:
22.5 miles per hour x 2.5 hours = 56.25 mile.
The train is 60 miles from it's destination, so now you want to subtract the miles it will travel in 2.5 hours from the total distance:
60 miles - 56.25 miles = 3.75 miles away from its destination.
