it costs $4 to enter the fair. each ride costs $2.50. You have $21.50. how many rides can you ride? write a equation

2 answers:

4 0

4+2.50x=21.50

You know you need 4 dollars to enter so you have that then 2.50 is the cost for one ride and x is how many rides you can ride

To solve you need to solve for x by subtracting 4 on both sides then dividing both sides by 2.50

Answer:

7 rides

Equation 21.50 = 2.50x + 4

Step-by-step explanation:

21.50 - 4 = 17.50

17.50/2.50 = 7

21.50 = 2.50x + 4

x is the amount of rides

The above question is a mathematical proof of the relationship between Lines and angles related to a Rhombus. See the proof below.

<h3>What is a Rhombus?</h3>

A Rhombus is a parallelogram with four sides (that is a quadrilateral). It's sides however are all of equal length.

<h3>What is the above proof?</h3>

∠DEC ≅ ∠BFC Reason = All Right Angles with Equal dimensions are congruent.

∠C ≅ ∠C Reason = It is the same angle for the two Right angles above which are congruent, hence Reflexive Property.
Δ DEC ≅ Δ BFC Reason = Angle Angle Side. The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle.
$\overline {DC}$ ≅ $\overline {BC}$ Reason = The corresponding parts of congruent triangles are congruent. Also, it is a parallelogram with all congruent sides.
ABCD is a Rhombus Reason = Its sides are all congruent.
