Answer:
AC = 7.5 cm
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
, that is
= 
( cross- multiply )
7AC = 52.5 ( divide both sides by 7 )
AC = 7.5 cm
Answer:
(2,-4)
Step-by-step explanation
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
Answer: x=3.2 AC= 42.8
Step-by-step explanation:
As point B lies at segment AC AC=AB+BC
Otherwise we can write the equation
5x+9x-2=11x+7.6
14x-2=11x+7.6
14x-2+2=11x+7.6+2
14x=11x+9.6
14x-11x=11x-11x+9.6
3x=9.6
x=9.6:3
x=3.2
AC= 11*x+7.6= 11*3.2+7.6=35.2+7.6=42.8
Answer:
Step-by-step explanation:
I'll give a couple answers so you get the gist of things.
All you have to do is substitute 1/2 for x and 3/4 for y.
Ex - 30. x × y = 1/2 × 3/4 = 3/8
