Step-by-step explanation:
Answer: The combined amount of kids and adult meals sold = 36
Step-by-step explanation:
Let the number of kids meals sold = 5x and the number of adult meals = 4x
Since total kids meals sold = 20
Then, 5x= 20
⇒ x =4
Adult meals = 4(4) = 16
Combined meals sold = kids meals + Adult meals
= 20+ 16
= 36
Hence, the combined amount of kids and adult meals sold = 36
Answer:
-8.8
Step-by-step explanation:
We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.

We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.

Now, move 4.3v across by subtracting it from both sides.


Finally, we divide both sides by the coefficient of v.

They are similar triangles because they are both right triangles
