Answer:
Step-by-step explanation:
Earth volume is approximately V = (4/3)πr³, and
Uranus volume is approximately V = (4/3)π(4r)³, or (4/3)π*64*r³
Comparing these two results, we see that the volume of Uranus is approximately 64 times greater than the volyume of Earth.
Y = mx + b is in the form of slope-intercept.
From the equation given, y + 2x = y - 2, we can convert it in the format of the slope intercept form and it depends we can came up to that form.
y + 2x = y -2
y - y = -2x - 2
0 = 2x + 2
x = -1
Unfortunately, the form y = mx + b is impossible to achieve.
Given:
Tom's earnings: x
Jan's earnings: 2x - 150
Total earnings: 1380
x + 2x - 150 = 1380
3x = 1380 + 150
3x = 1530
3x/3 = 1530/3
x = 510
Tom's earnings: x = 510
Jan's earnings: 2x - 150 = 2(510) - 150 = 1,020 - 150 = 870
total earnings: 1,380
510 + 870 = 1,380
1,380 = 1,380
