Answer:
Terrance would take 4.2666 hours, Jesse would take 6.25 hours
Step-by-step explanation:
1h/12m per hour x 50m/1h is also 50m/12m per hour = 4.266 hours (round number)
1h/8m per hour is also 50m/8m per hour = 6.25 hours (round number)
Answer:
Commutative Property
Step-by-step explanation:
Commutative property is the property where if you change the order of the operands, it does not change the result.
You could buy 35 magazines. Hope this helps :)
7 = a/2 + 4
first subtract 4 from both sides
7 (-4) = a/2 +4 (-4)
3 = a/2
Then isolate a by multiplying 2 to both sides
3(2) = a/2 x 2
6 = a
a = 6
hope this helps
4x - 3y = -11
-7x - 8y = 6
We need to cancel out one of the variables so let's multiply the first equation by 8 and the second by 3 and aim to cancel y.
32x - 24y = -88
-21x - 24y = 18
Now we subtract,
53x = -106
x = -2
3y = 4x + 11 = 4(-2) + 11 = 3
y = 1
Answer: (x,y)=(-2,1)
Check:
4(-2) -3(1) = -8 - 3 = -11, good
-7(-2) - 8(1) = 14 - 8 = 6, good
