You take out a GCF, greatest common factor.
Answer:
x = 1/10
Step-by-step explanation:
2/x -2 = 3/2x +3
Add 2 to each side
2/x -2+2 = 3/2x +3+2
2/x = 3 /2x +5
Subtract 3/2x from each side
2/x -3/2x = 3 /2x - 3/2x +5
2/x - 3/2x = 5
Get a common denominator
2/x *2/2 -3/2x =5
4/2x - 3/2x = 5
1/2x =5
Multiply each side by 2x
1 /2x * 2x = 5 *2x
1 = 10x
Divide each side by 10
1/10 = 10x/10
1/10 =x
Answer:
Changing the order of addends does not change the sum.
Step-by-step explanation:
For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4. Associative property of addition: Changing the grouping of addends does not change the
7/12 of 1 hour:
1 hour = 60 min.
7/12 * 60
7 * 5 = 35
Francis ran 2 1/2 miles in 35 min.
2 1/2 = 5/2
5/2 miles = 35 min
x miles = 60 min
(Cross Multiply)
5/2 * 60 = 35x
5 * 30 = 35x
150 / 35 = x
x = 30 / 7 = 4 2/7 miles
Francis ran 4 2/7 miles in one hour.
