<span>8x = 2y + 5
3x = y + 7 so y = 3x - 7
substitive </span>y = 3x - 7 into 8x = 2y + 5
8x = 2y + 5
8x = 2(3x - 7) + 5
8x = 6x - 14 +5
2x = -9
x = -4.5
y = 3x - 7
y = 3(-4.5) - 7 = -13.5 - 7 = -20.5
solutions (-4.5, -20.5)
Answer:
-200, 3, 10, -8, 2, -7
Step-by-step explanation:
1. A drop of 200 feet
Integer Value =-200
A point of zero means there is no decrease/increase in the height. No drop from present point.
2. An expansion of 3 cubic meters
Integer Value =3
A point of zero means there is no expansion.
3. Earn 10 points
Integer Value=10
A point of zero means there is no increase in points. No point is earned or added.
4. Reduce by 8 inches
Integer Value=-8
A point of zero means there is no change in the length of height of the given object.
5. Gain 2 pounds
Integer Value=2
A point of zero implies no pound or weight was gained.
6. A drop of 7 degrees
Integer Value=-7
A point of zero implies that there is no change in degrees.
Nine billion, three million, eight hundred forty thousand, one hundred sixty five
I am not sure but its might be .125
