Same question
x+y=30
x is 1/5 of y
x=y/5
subsitute
y/5+y=30
multily both sidse by 5
y+5y=150
add
6y=150
divide both sides by 6
y=25
subsitute
x=y/5
x=25/5
x=5
the numbers are 5 and 25
Answer:
13 units
Step-by-step explanation:
Use the distance formula, d = 
, where (x2, y2) and (x1, y1) are two different points on the line.
Plug in the values:
d =
d = 
d = 
d = 
d = 
d = 13
Like in real life problems?
if yes then when conducting a survey, when grading quizzes/assignments, etc
1/5 (150x - 80y + 50 - 50x - 25y + 20) = 20x - 21y + 14
what I did is combined the like terms and multiplied each term within the parenthesis by .2
