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:
Take out 4:
4(x^2-8x)-12
=4(x^2-8x+16-16)-12
=4(x^2-8x+16)-64-12
=4(x^2-4)^2 - 76
=
Answer:
Angle DOC
Step-by-step explanation:
Since angle AOC and angle DOC are ajacent angles that form a straight line, they are supplementary to each other.
By the definition of supplementary angles, you can determine that angle AOC + angle DOC = 180.
Also notice that angle DOC is a right angle (90 degrees), so you can also determine that angle AOC is also a right angle since they are supplementary.
