X represents the number that would be added to the silver cars.
x/40= 4
X=40x4
x=160
Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
(16 - Sqrt(11))/(-2)
= -8 +Sqrt(11)/2
Answer:
x=16
Step-by-step explanation:
Because this is an isosceles triangle the angle 2x+3 is the same as the missing angle. The angles in triangles add up to 180 degrees. 180-110=70.
Because the two angles are the same you can divide 70 by 2 to get 35.
35=2x+3.
35-3=2x+3-3
32=2x
32/2=2x/2
16=x
Answer:
x^2 - 11x + 24
Step-by-step explanation:
Foil the equation
x^2 - 3x - 8x + 24
x^2 - 11x + 24
