1.44 yards=54 in
1.44(3.40)=$4.91
$20.00 - $4.91=$15.09
The question is asking for a point at which the two values would intersect, so i think that it is looking for a solution. in this case, i would solve the equations: y=0.15x+19 and y=0.19x.
the point of intersection for these equations is (475, 90.25). you are looking for the x value, so the answer would be 425 minutes of calling for the two plans’ costs to be equal.
you do 77 divided by 14 you get 5.5 so the greatest number of teams is 5.
1a+27
4a-3a= 1a
21+6= 27
1a+27
3 boys + 8 girls = 11 students
3 boys/ 11 students = x boys /33 students
using cross products
3 * 33 = x*11
divide by 11
99/11 = x
x=9
There are 9 boys
