Answer:
-5 , 20
Step-by-step explanation:
<h3>
Forming system of linear equations and solving:</h3>
Let x and y be the first and second number respectively.
3x + y = 5 -------------(i)
y = 5 - 3x
2x + y = 10 -------------(ii)
Method used for solving: substitution method.
Substitute y = 5 - 3x in equation (ii)
2x + 5 - 3x = 10
2x - 3x + 5 = 10
Combine like terms,
-x + 5 = 10
Subtract 5 from both sides,
-x = 10 - 5
-x = 5
Multiply the entire equation by (-1)
y = 5 - 3*(-5)
= 5 + 15
Answer:
x+9x+x+100=1178
11x=1178-100
x=1078/11
x=98
Step-by-step explanation:
Parallel lines share the same slope, so the slope of the parallel line in this case must be .
Point-slope form is , where is the slope and is any known point on the line.
Plug in the values.
Simplify and distribute.
Subtract 1 from both sides.
9 because every ten plants is equal to 3 gallons. 30 plants are equal to 9 gallons.
