Answer:
Step-by-step explanation:
n+8+6
-- 9 people paint 5 walls in 60 minutes
-- 9 people paint (5 / 5) = 1 wall in (60 / 5) = 12 minutes
-- (9 / 9) = 1 person paints 1 wall in (9 x 12) = 108 minutes
-- 1 person paints (1 x 6) = 6 walls in (108 x 6) = 648 minutes
-- (1 x 4) = 4 people paint 6 walls in (648 / 4) = 162 minutes .
Answer:
10
Step-by-step explanation:
2(6+1) - |-10| + 3*2
= 2 (7) - (+10) + 6
= 14 - 10 + 6
= 20 - 10
= 10
Answer:
Parallel line:
Perpendicular line:
Step-by-step explanation:
we are given equation 4x+5y=19
Firstly, we will solve for y
we can change it into y=mx+b form
so,
Parallel line:
we know that slope of two parallel lines are always same
so,
Let's assume parallel line passes through (1,1)
now, we can find equation of line
we can plug values
now, we can solve for y
Perpendicular line:
we know that slope of perpendicular line is -1/m
so, we get slope as
Let's assume perpendicular line passes through (2,2)
now, we can find equation of line
we can plug values
now, we can solve for y
