Mathematics Middle School

The school band is selling candy to raise $1,800.00 to pay for their trip to a band festival. The band earns $1.50 from every box of candy sold. Kayla solved the inequality 150 x greater-than-or-equal-to 1,800 to find the number of boxes the band must sell to meet their goal. She graphed her solution on a number line and interpreted the solution to mean the band will meet their goal if they sell fewer than 12 boxes.

A number line going from 6 to 16. A closed circle is at 12. Everything to the right of the circle is shaded.

What errors did she make? Select two options.
She used the wrong coefficient for x in her inequality.
She should have used the less than or equal to symbol instead of the greater than or equal to symbol.
She interpreted the graph incorrectly.
She graphed a solution set that does not match her inequality.
The graph should have an open circle at 12.

x = 0 is a vertical line.

If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

The answer is (-3,4) because mirrored give you -3 and then mirror the -4 and you get just 4

A swimming pool holds 250,000 gallons of water and is being drained at 200 gallons per minute. How many gallons remain in the pool after 5 minutes than after 20 minutes?

Answers

Answer:

After 5 minutes, the pool will hold 249,00 gallons of water.

After 20 minutes, the pool will hold 246,000 gallons of water.

After 5 minutes the pool will have 249,000 gallons since 5x200=1000 and 250,000-1000=249,000.
After 20 minutes it will be at 246,000 gallons since 20x200=4000 and 250,000-4000= 246,000.
