Answer:

\frac{31x-159}{168y}

Step-by-step explanation:

\frac{x-4}{7y} - \frac{x+7}{8y} + \frac{x+3}{6y}

the LCD of the denominators is 168y , then

\frac{24(x-4)-21(x+7)+28(x+3)}{168y} ← distribute and simplify numerator

= \frac{24x-96-21y-147+28x+84}{168y}

= \frac{31x-159}{168y}

Answer:

\frac{31x - 159}{168y}

Step-by-step explanation:

First we need to find a common denominator between 7y, 8y, and 6y. And the smallest common denominator is 336y, which I got by multiplying 7*8*6 and since they all share y, we can just keep the y without multiplying it.

Now, we need to multiply each fraction by the correct number on the top and bottom to reach 336. When we do this, we get \frac{x-4}{7y} (\frac{48}{48} ) - \frac{x+7}{8y}(\frac{42}{42}) + \frac{x+3}{6y}(\frac{56}{56}). OMG. Well, now we need to expand the numerators...\frac{48x - 192}{336y} - \frac{42x + 294}{336y} + \frac{56x + 168}{336y}  = \frac{62x - 318}{336y}. Another OMG. But now we need to simplify...so we get \frac{31x - 159}{168y}. Done.

Hope this helps! :)

nignag [31]

Answer:

Number of nickels = 17

Number of dimes = 23

Step-by-step explanation:

Let

x = number of nickels

y = number of dimes

x + y = 40 (1)

0.05x + 0.10y = 3.15 (2)

From (1)

x = 40 - y

Substitute x = 40 - y into (2)

0.05x + 0.10y = 3.15 (2)

0.05(40 - y) + 0.10y = 3.15

2 - 0.05y + 0.10y = 3.15

- 0.05y + 0.10y = 3.15 - 2

0.05y = 1.15

y = 1.15/0.05

y = 23

Substitute y = 23 into (1)

x + y = 40 (1)

x + 23 = 40

x = 40 - 23

x = 17

Number of nickels = 17

Number of dimes = 23

PolarNik [594]
Hey there,
Total distance = 7 / 10 x 4
                       = 2 4/5 miles
3 times = 2 4/5 x 3
            = 8 2/5
1/2 times = 2 4/5 / 1/2
                = 5 3 /5
8 2/5 + 5 3/5 = 14 miles

Hope this helps :))
