Answer:
r = 1/5 or 0.2
Step-by-step explanation:
5/6r = 1/6
Divide everything by 5/6
6/30 simplified is 1/5.
X=amount of money Ofeila hasx-$12=(1/5)xLet's eliminate the fractions by multiplying both sides by 5...5(x-$12)=(5)(1/5)x5x-$60=xLet's subtract 5x from both sides...-5x+5x-$60=x-5x-$60=-4xLet's divide both sides by -4...(-$60)/(-4)=(-4x)/(-4)$15=x -< AnswerLet's check our work...x-$12=(1/5)x$15-$12=(1/5)($15)$3=$3
Let Home runs = X
Triples would be X-3 ( 3 less triples than home runs)
Doubles would be 3x ( 3 times as many doubles as home runs)
Singles would be 45(x-3) ( 45 times as many singles as triples)
Simplify the equation for singles to be 45x-153
Now you have X + x-3 + 3x + 4x-135 = 262
Simplify:
50x - 138 = 262
Add 138 to both sides:
50x = 400
Divide both sides by 50:
x = 400/50
x = 8
Home runs = x = 8
Triples = x-3 = 8-3 = 5
Doubles = 3x = 3(8) = 24
Singles = 45(x-3) = 45(8-3) = 45(5) = 225
In order to calculate the area of a triangular prism, You can use the formula,
Area = 1/2 * a * c * h
Hope this helps!
