Answer:
800
Step-by-step explanation:
Look at the tens if it's 0-4 keep the number the same if 5-9 go up one number
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

Im pretty sure you need to divide 155 by 4 or 48. try it and see what you get. then ask your teacher if you did it right. always ask questions.
Im pretty sure that the answer it is A. 7
because if you subtract 2 from 7 you get 5
