Answer: x = 2 and y = -4
x + 2y = -6
x = -6-2y
Putting this in value of x in
6x + 2y = 4
6(-6-2y) + 2y = 4
-36-12y+2y = 4
-10y = 4+36
y = 40/(-10)
y = -4
Now putting this value of y in
x + 2y = -6
x + 2(-4) = -6
x -8 = -6
x = -6+8
x = 2
Therefore x = 2 and y = -4
If we put these values we can check this
x + 2y = -6
2 + 2(-4) = -6
2 -8 = -6
-6 = -6

Answer: 300000000000000 Scientific Notation: 3 x 10^14
Step-by-step explanation: (5 x 10^4) = 50000 (6 x 10^9) = 6000000000
50000 x 6000000000 = 300000000000000
Answer:
g/c = x
Step-by-step explanation:
g= xc
/ c
g/c = x
isolate x by dividing out c
<span>Number of roses (r) in a garden increases when the number of weeds (w) decreases, this supports an inverse relationship between the two variables.
The formula is then therefore, r = k/w
Solve for constant first.
r = k/w
20 = k/10
200 = k
r=200/5
r=40 roses
40 roses when there are 5 weeds.
