Work = force *distance
W= weight *height
W= (10kg) (9.8 N/kg)(2m) = 198 Joules
Hope this helps!
It moves 21 inches.
36 divided by 12 is 3 and 3 times 7 is 21. That simple
Y = 10x + 400
y = 30x + 300
10x + 400 = 30x + 300
20x = 100
x = 5 months(answer to first question)
y = 10(5) + 400
y = 450
After 5 months, Tina will save $450 with either option.
Your answer should be b and d
Simple, your answer is B. You add what's inside the () and then you add it to -21 because both numbers are negative meaning they add up.
