Yes because if you divide both, the numerator and denominator, by 7 it would simplify to 10/3, so they are equivalent.
Answer:123
Step-by-step explanation:
Answer:
w=30 l=125
Step-by-step explanation:
Perimeter =2l+2w
p=310
w =width
4w+5 = length(4 times plus 5 the width)
2(4w+5) + 2w = 310
8w+10 = 2w =310
10w=300
w=30
30*4=120 120+5=125 l=125
2(125)+ 2(30)= 250+60 =310
Take the length as 'x'
Width = 2x - 2
Perimeter = 44 [ Formula = 2(l + w) ]
2 (l + w) = 44
2 (x + 2x - 2) = 44
2 (3x - 2) = 44
6x - 4 = 44
6x = 44 + 4
6x = 48
x = 48/6
<u>x </u><u>=</u><u> </u><u>8</u> => length
Width = 2x - 2 = 2(8) - 2 = <u>1</u><u>4</u><u> </u><u>units.</u>
Hope it helps!

Answer:
Laura is 30 years old and Maria is 18 years old.
Step-by-step explanation:
Let x be the present age of Laura and y be that of Maria.
Laura was 3 times older than Maria when Laura had Maria's present age.
Lets say Laura had Maria's present age(y) k years before.Then Maria's age at that time will be y-k where k=(x-y).
Then:
y=3(y-k)
y=3(y-(x-y))
y=3(2y-x)
3x=5y -------1
After two years Laura will become x+2 years old and 2 years ago Maria was y-2 years old. Then:
x+2=2(y-2)
x=2y-6--------2
Solving 1 and 2 we get:
x=30 and y=18
Hence Laura's present age is 30 and Maria's present age is 18.
