A group of friends on a camping trip has 325 lb of trail mix. They divide it up evenly among themselves. Each person gets 15 lb

SVEN [57.7K]

325 lb brought

15 lb each

325/15 = 21.6 people

or 21 people can get a full 15 lbs and 1 person gets .6 of 15 lb or 9 lb

Solve for p and q if<br>p+q=2(p-q)<br>pq=675

IgorC [24]

Step-by-step explanation:-

Let p + q = 2( p - q) be eqn.1 and pq = 675 be eqn.2

Now , lets expand eqn.1

$=> p + q = 2p - 2q$

$=> 2p - p = 2q + q$

$=> p = 3q$

Lets put the value of p in eqn.2

$=> 3q \times q = 675$

$=> 3q^{2} = 675$

$=> q^{2} = \frac{675}{3} = 225$

$=> q = \sqrt{225} = +15 \: or \: -15$

Lets find out the value of p.

When q = +15 , $p = 3 \times 15 = 45$

When q = -15 , $p = 3 \times - 15 = -45$

Hence ,

p = ±45

q = ±15

What’s is 5x/2 + 3 = 1/7

galina1969 [7]

For this case we must solve the following equation:

$\frac {5x} {2} + 3 = \frac {1} {7}$

We subtract 3 from both sides of the equation:

$\frac {5x} {2} = \frac {1} {7} -3\\\frac {5x} {2} = \frac {1-21} {7}\\\frac {5x} {2} = \frac {-20} {7}\\\frac {5x} {2} = - \frac {20} {7}$

We multiply by 2 both sides of the equation:

$5x = - \frac {40} {7}$

We divide by 5 on both sides of the equation:

$x = - \frac {40} {7 * 5}\\x = - \frac {8} {7}$

Answer:

The solution is: $x = - \frac {8} {7}$
