Answer: 30
Step-by-step explanation:
Let the number be y
Add 5 to me
Y+5............equ1
Divide by 7
Y+5/7
Add 12
Y+5/7+12
Subtract 7
(Y+5)/7+(12-7)=10
12-7=5
Substitute 
(Y+5)/7+5=10
Find the lowest common multiple 
((Y+5)+7(5))/7=10
(Y+5)+35)/7=10
Cross multiply 
Y+5+35=70
Y+40=70
Y=70-40
Y=30
The unknown number is 30
 
        
             
        
        
        
Answer:
Step-by-step explanation:
in this expression we have
two variables: 6x and 10p
one constant 5
3 terms
 
        
             
        
        
        
The value of y is 83 degrees because any quadrilaterals opposite sides or angles are equal and opposite (or diagonal) from point D.

Answer:
Measure of ∠BCP is 36°
Step-by-step explanation:
Given the circle in which measure of arc BC is 72°
we have to find the measure of angle BCP.
m∠BOC=∠2=72°
By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.
∴ ∠2=2∠1 ⇒ 72=2∠1
⇒    ∠1=36°
By alternate segment theorem which states that
The angle formed between a chord and a tangent through one of the end points of chord is equals to angle in alternate segment.
⇒ ∠3=∠1=36°
Hence, measure of ∠BCP is 36°
Option D is correct
