Answer:
x = -2, y = -3
Step-by-step explanation:
y - 3x = 3
x - 2y = 4
-3x + y = 3
x - 2y = 4
-6x + 2y = 6
x - 2y = 4
Add the equations.
-5x = 10
x = -2
Substitute -2 for x in the first original equation and solve for y.
y - 3x = 3
y - 3(-2) = 3
y + 6 = 3
y = -3
Answer: x = -2, y = -3
Answer:
x<3
Step-by-step explanation:
5x+2<17
Subtract 2 from both sides.
5x<17−2
Subtract 2 from 17 to get 15.
5x<15
Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.
x=15/5
Divide 15 by 5 to get 3.
x<3
Answer:
Area
Step-by-step explanation:
Area of a rectangle = L x W
The measurement of the room is 6m by 10m
So,
Area = 6 x 10
= 60 square meters
Answer:
40/3
Step-by-step explanation:
w = weight of soil needed
f = number of flower beds
a = constant value
w = a * f
<em>substitute</em>
10 = 6a
<em>simplify</em>
5/3 = a
w = (5/3)f
<em>plug in 8</em>
w = (5/3)(8)
<em>simplify</em>
w = 40/3
