Answer:
x = 126°
Step-by-step explanation:
x + 54 = 180°
x + 54 - 54 = 180 - 54
x = 126°
Step-by-step explanation:
one of the action that some European leaders did that led to requests
for the league of nations to help is Tney invaded other countries to gain new territory
You can just add the terms:
<span>(-x^2+9)+(-3x^2-11x+4) = -4x</span>² - 11x + 13
24 girls divided by 6 girls = 4 boys. 3 boys for every girl and there is 6 girls so you would do 4 x 3 = 12 boys.
So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
