The bike shop made $28 dollars profit. First, you add the cost of the bike and the cost of the helmet, which is $84. Then you divide that by 150 to get what 1% would be, which is .56. Then you multiply that by 50%, which is the part of the price that the shop profited, which is $28.
Answer:
x=93
Step-by-step explanation:
Add 13 by both sides
x/3 - 13 + 13 = 18 + 13
simplify
x/3 =31
Multiply both sides by 3
3x/3=31 times 3
simplify
x= 93
m=-(5/4)
From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.
The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.
In every slope, there’s a numerator, being the rise, and a denominator, being the run.
To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.
To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.
With these two numbers and the negative sign, we get -(5/4) as our slope.
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.
≅ 
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.
