Answer:

$x = 35$

Step-by-step explanation:

We can use Similar Triangles Ratios to solve for the missing side length. First setup your ratios:

$\frac{42}{6} = \frac{x}{5}\\x = \frac{42}{6} \times 5\\x = 35$

Answer:

35

Step-by-step explanation:

The sides are in proportion.

$\frac{AB}{PQ} =\frac{AC}{PR}$

? / 5 = 42 / 6
? = 5 × 7
? = 35

A store sells two different types of coffee beans; the more expensive one sells for $8 per pound, and the cheaper one sells for

Slav-nsk [51]

So,

Let the amount of the expensive coffee beans be x, and the amount of the less expensive coffee bean be y.

The number of pounds of coffee beans is 50.
x + y = 50

$8 times the amount of more expensive coffee beans plus $4 times the amount of less expensive coffee beans divided by 50 equals $6.50.
$\frac{8x + 4y}{50} = 6.50$

Now, all we have to do is use Elimination by Substitution.
x + y = 50

Subtract y from both sides.
x = 50 - y

Substitute 50 - y for x in the second equation.
$\frac{8(50 - y) + 4y}{50} = 6.50$

Distribute.
$\frac{400 - 8y + 4y}{50} = 6.50$

Collect Like Terms.
$\frac{400 -4y}{50} = 6.50$

Simplify.
$\frac{4(100 -y)}{2*5^2} = 6.50$
$\frac{2(100 -y)}{5^2} = 6.50$
$\frac{200 - 2y}{25} = 6.50$

Multiply both sides by 25.
$200 - 2y = 162.5$

Add 2y to both sides.
$200 = 162.5 + 2y$

Subtract 162.5 from both sides.
37.5 = 2y

Divide both sides by 2.
18.75 = y

Substitute in an earlier equation to solve for x.
x = 50 - y
x = 50 - 18.75
x = 31.25

Check.
31.25 + 18.75 = 50 lbs.

$\frac{8x + 4y}{50} = 6.50$
$\frac{8(31.25) + 4(18.75)}{50} = 6.50$
$\frac{250 + 75}{50} = 6.50$
$\frac{325}{50} = 6.50$
$\frac{5^2*13}{2 * 5^2} = 6.50$
$\frac{13}{2} = 6.50$
6.50 = 6.50 This also checks.

There were 31.75 pounds of the more expensive coffee bean and 18.75 pounds of the less expensive coffee bean.
