"None" is a your clue word... if "none" means zero, then there is still "6 birds" because 0 left.
In a equation it will look like this: 6 - 0 = 6
Given:
A bricklayer is able to set 2.5 bricks in one minute.
Required:
To find the number of bricks can he set in 8 hours.
Explanation:
8 hours =480 minutes.
2.5 bricks in one minute.
So for 480 minutes,

Final Answer:
1,200 bricks can he set in 8 hours.
Answer:
a = 77°
Step-by-step explanation:
Two angles are complementary if their sum is 90 degrees.
Let us assume that the angle b is complement of a.
Given statement complement (complement (a)) = complement (b) = a
Complement (complement (77°)) = complement ( 13°) = 77°
The conclusion is obvious that this is the same angle.
God with you!!!
Answer:
r = 1
Step-by-step explanation:
Use the distributive property to multiply −6 by −3+5r.
18−30r=−5−7r
Add 7r to both sides.
18−30r+7r=−5
Add −30r and 7r to get −23r.
18−23r=−5
Subtract 18 from both sides.
−23r=−5−18
Subtract 18 from −5 to get −23.
−23r=−23
Divide both sides by −23.
r=−23/−23
Divide −23 by −23 to get 1.
r=1
