x = 10
Step-by-step explanation:
By the converse of the side-splitter theorem, if , then KM ∥ JN.
Substitute the expressions into the proportion:
Cross-multiply:
(x – 5)(x+4) = x(x – 3).
Distribute:
Multiply and simplify:
Solve for x: x = 10
Therefore, the value of x that would make KM parallel to JN is 10.
Answer:
An ice cream cone with 5 scoops cost is, $4.5
Step-by-step explanation:
As per the statement:
An ice cream stand uses the expression to determine the cost of an ice cream cone that has x scoops of ice cream.
⇒ Cost of an ice cream cone C(x) = .....[1]
Given: x = 5 scoops
We have to find the cost of an ice cream cone with 5 scoops cost.
Substitute the given value of x =5 in [1] we have;
C(5) =
C(5) = = 2 + 2.5 = $4.5
Therefore, an ice cream cone with 5 scoops cost is, $4.5
