The value of a certain fraction becomes 1/5 if one is added to its numerator. If one is taken away from its denominator, its val
Lana71 [14]

Answer:

\frac{2}{15}

Step-by-step explanation:

Let the original fraction be \frac{x}{y}

Then adding 1 to the numerator gives

\frac{x+1}{y} = \frac{1}{5} ( cross-  multiply )

⇒ y = 5x + 5 → (1)

Subtracting 1 from the denominator gives

\frac{x}{y-1} = \frac{1}{7} (cross-  multiply )

y - 1 = 7x → (2)

Substitute y = 5x + 5 into (2)

5x + 5 - 1 = 7x ← subtract 5x from both sides

4 = 2x ⇒ x = 2

Substitute x = 2 into (1)

y = (5 × 2) + 5 = 10 + 5 = 15

Hence original fraction = \frac{2}{15}

OlgaM077 [116]

Answer:

12 quarters 23 dimes

Step-by-step explanation:

x(0.25)+(2x-1)(0.10)=5.30

0.25x+0.2x-0.10=5.30

0.45x=5.40

x=12

12 quarters

12(2)=24-1=23 dimes

oee [108]

Answer:

yes

Step-by-step explanation:

Yes it is, assuming we decide to use the Pythagorean Theorem to find the hypotenuse (10) it'll be possible considering the formula is c²=√a²+b²

(c being the longest side of the triangle)

a= 6 and b= 8
