Answer:

Donna swims 8 km each week.

Step-by-step explanation:

To be able to find the answer, you have to consider that 1 km is equal to 1000 meters and with this, you can use rule of three to find the kilometers in 8000 meters:

1 km → 1000 meters

x ← 8000 meters

x=(1*8000)/1000=8 km

According to this, the answer is that Donna swims 8 km each week.

A shop sells a party hat at x dollars and a mask at y dollars. On a particular morning, 3 hats and 4 masks were sold for $27. In

Aleks [24]

Answer:

Cost of each hat: $5

Cost of each mask: $3

Step-by-step explanation:

Let be "x" the cost in dollars of a party hat and "y" the cost in dollars of a mask.

Set up a System of equations using the information given in the exercise:

$\left \{ {{3x+4y=27} \atop {3x+6y=33}} \right.$

You can use the Elimination Method to solve this System of equations:

1. You can multiply the first equation by -1.

2. Then you must add the equations.

3. Solve for "y".

Then:

$\left \{ {{-3x-4y=-27} \atop {3x+6y=33}} \right.\\.....................\\2y=6\\\\y=\frac{6}{2}\\\\y=3$

4. Now you can substitute the value of "y" into any original equation.

5. Finally, solve for "x" in order to find its value.

Then:

$3x+4(3)=27\\\\3x=27-12\\\\x=\frac{15}{3}\\\\x=5$
