C = child tickets
a = adult tickets
Solve this with the substitution method.
Make two equations:
6.30c + 9.90a = 1,246.50
c + a = 159
Solve for c.
Subtract 9.90a from both sides.
6.30c = 1,246.50 - 9.90a
Divide both sides by 6.30.
c = 197.86 - <span>1.57a (rounded to hundredths)
Plug c into second equation.
</span>197.86 - 1.57a + a = 159
Combine like terms.
197.86 - 0.57a = 159
Subtract 197.86 from both sides.
-0.57a = -38.86
Divide both sides by -0.57.
a = <span>68.18
round up to ones: 68

Answer:
(z+2)(z+3)(x-8)
Step-by-step explanation:
z² + 5z + 6 can be factored into (z+3)(z+2)
zx + 2x − 8z-16 can be factored into (x-8)(z+2)
the LCM would be (z+2)(z+3)(x-8)
if you were to multiply the two expressions together, you would multiply (z+2)^2, which is not necessary for LCM, which is why you factor them first
(10-4)/(7-5)=6/2=3.
The slope of the line that passes through those two points is 3.
Answer:
x=11 and t=6
Step-by-step explanation:
If ABC and KLM are approximately equal, 44 degrees=4x and 18 inches=3t.
44/4=11
18/3=6
