If Greg deposited $120 into his account and Thomas increased his money by 20% and they still got the same amount in November, it means that $120 is 20% of their money in October.
120 = 20% * x (where x is the money in October)
120 = 20/100x
120 = 2/10x
120 = 1/5x / * 5 (both sides)
x = 600
So each of them had $600 in October.
Doublecheck:
Greg's money = 600 + 120 = 720
Thomas' money = 600 + 20% * 600 = 600 + 120 = 720
So it's correct :)
Given:
Rectangle shape.
Length is 3 feet longer than its width
Width is unknown let it be x.
Perimeter is 26 feet
Perimeter = 2Length + 2Width
26 ft = 2(x+3) + 2x
26 ft = 2x + 6 + 2x
26 ft = 4x +6
26 ft - 6 = 4x
20 ft = 4x
20 ft / 4 = x
5 ft = x
The width is 5 feet.
Length is 3 ft longer than the width. Thus, it is 8 feet.
To check:
perimeter = 2L + 2W
26 ft = 2(8ft) + 2(5ft)
26 ft = 16 ft + 10ft
26 ft = 26 ft
