Answer:
Solution:
Given, cost price = $784.50
Profit = 6.5% of cost price
= 6.5/100 × $784.50
= $50.9925 [since, profit% is always on C.P.]
And selling price = cost price + profit
= $784.50 + $50.9925
= $835.4925
Hence, selling price = $835.4925
The missing steps are each right angles and
.
Solution:
Step 1: Given data:



Step 2: In the two polygons,
and 
(Each right angle)
Step 3: Given

Step 4: By third angle theorem,
If two angles in one triangle are congruent to the two angles in the other triangle, then the third angles in the triangles also congruent.

Step 5: By the definition of congruent polygons,
If two same shape polygons have all the angles are congruent and all the corresponding sides are congruent then the polygons are congruent.
Hence
.
Therefore the missing steps are each right angles and
.
Answer:
6x - y = - 6
Step-by-step explanation:
Given
y + 6 = 6(x + 2) ← distribute parenthesis
y + 6 = 6x + 12 ( subtract y from both sides )
6 = 6x - y + 12 ( subtract 12 from both sides )
- 6 = 6x - y OR 6x - y = - 6 ← in the form Ax +By = C
The student completed 13 courses with 3 credit hours.
Step-by-step explanation:
Total credit hours = 59 credits hours
Total courses = 18
Let,
3 credit hours courses = x
4 credit hours courses = y
According to statement;
x+y=18 Eqn 1
3x+4y=59 Eqn 2
Multiplying Eqn 1 by 3

Subtracting Eqn 3 from Eqn 2

Putting y=5 in Eqn 1

The student completed 13 courses with 3 credit hours.
