Answer:

Neither.

Step-by-step explanation:

Parallel lines have equivalent slopes while perpendicular lines have opposite reciprocal slopes. (Opposite meaning different signs and reciprocal meaning flipped fraction)

Ex: 3/4 → -4/3

$wx:~m=\frac{4-3}{6-(-3)}\\wx:~m=\frac{1}{9}\\\\yz:~m=\frac{-6-(-4)}{8-6}\\yz:~m=\frac{-2}{2}\\yz:~m=-1$

These lines are neither parallel nor perpendicular.

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots inclu

Pepsi [2]

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

$99.90 + 89.90 = 189.80$

Step 2: Find the sales tax of the result

$\frac{8}{100}\times 189.8 = 15.184$

Step 1: Convert 8% to fraction
$8\%= \frac{8}{100}$
Simplify
$\frac{8}{100} = \frac{2}{25}$
Step 2: Convert 189.80 to a fraction
$189.80 = \frac{189.8}{1}$
Step 3: Set it up
$\frac{2}{25}\times \frac{189.8}{1}$
Step 4: Cross divide
$189.80 \div 25 = 7.592\\2 \div 1 = 2$
Step 5: Multiply the result
$7.592 \times 2 = 15.184$

Step 3: Add the result from the total cost of both items

$189.80 + 15.184 = 204.98$

The total cost of the hats and boots including sales tax is 204.98 dollars

Jack has $6.00 less than twice the amount of money David has. Together they have $45.00. How much money does Jack have

Shalnov [3]

Answer:

Jack - $28

David - $17

Step-by-step explanation:

Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.

2d-6+d=45

3d-6=45

3d=51

d=$17

We can then substitute back and find 2(17)-6=34-6=$28.
