Answer:
Below.
Step-by-step explanation:
3x + 5y = 15
Subtract 3x from both sides:
5y = -3x + 15
Divide through by 5:
y = -3/5 x + 3 <-----------slope-intercept form
First off when multiplying fractions you always multiply straight across. so the answer would be -5/12.
Answer:
The answer to your question is: first piece = 4 in, second piece = 8 in, third piece = 12 in
Step-by-step explanation:
Data
total length = 24 inches
first piece = x in
second piece = 2x
third piece = 3x
Equation
x + 2x + 3x = 24
6x = 24
x = 24/6
x = 4 length of the first piece
second piece = 2(4) = 8 inches
third piece = 3(4) = 12 inches
