Answer:
the asnwer is C
Step-by-step explanation:
10. 25% of 40 or 0.25 times 40 gives you 10.
also 25% = 1/4
so 1/4 x 40 = 10
Answer:
Make Width = 'x'
Length = 4 + 2x
Perimeter = 2 x Width + 2 x Length
86 = 2(x) + 2(4 + 2x)
86 = 2x + 8 + 4x
Collect like terms:
2x + 4x = 86 - 8
6x = 78
x = 13
Width = 13 cm
Length = 30 cm
Step-by-step explanation:
Jane has read 108 pages, which leaves 92 pages to read (200 - 108). That is 92/200, which simplifies to 46/100 = 46%. Kevin has 80 pages left, which is 80/200, which simplifies to 40/100 = 40%. Therefore, Jane has got to read 6% more pages, which however is not on here. This could be a mistake in the question.
