For 2, work backwards. 93.34 divided by 18.69 equals what? That’s your E.
3, use multiplication. 4.30 times 8.60 equals your D.
4, you just do as the problem says.
5, you do the same as number 2.
6, you do the same as 3.
For the word problem, say how someone starts off with 51.15 and has to give that something to 5 people.
Answer:
y = 6
Step-by-step explanation:
3 y - x = 9
y = (2 x)/3
Substitute y = (2 x)/3 into the first equation:
{x = 9
y = (2 x)/3
Substitute x = 9 into the second equation:
Answer:
x = 9
y = 6
2 surfaces are 6 in by 9 in, meaning that their combined area is 2(54 in^2).
2 surfaces are 6 in by 18 in; combined area is 2(108 in^2).
2 surfaces are 9 in by 18 in; combined area is 2(162 in^2).
Add up these areas: A = 2(54+108+162) in^2 = 648 in^2 (answer)
You walk 0.5 miles every 10 minutes.
