Kelly works at an electronics store.    she is required to sell at least 12 items each month.    she makes a commission of $100 for each laptop and $80 for each smart phone. kelly wants to make more than $1000 for the month.    let x represent the number of laptops sold and y represents the number of smart phones sold.    determine which system of inequalities represents the situation.

x + y < 12 and 100x + 80y ≤ 1000
x + y ≥12 and 100x + 80y > 1000
x + y > 12 and 100x + 80y ≥ 1000
x + y ≤12 and 100x + 80y < 1000

Will possibly give brainliest and a high rating. choose the linear inequality that describes the graph. the gray area represents the shaded region. 4x + y > 4 4x – y ≥ 4 4x + y < 4 4x + y ≥ 4

Match the scale and the actual area to the area of the corresponding scale drawing. scale: 1 inch to 4 feet actual area: 128 square feet scale: 1 inch to 7 feet actual area: 147 square feet scale: 1 inch to 8 feet actual area: 256 square feet scale: 1 inch to 5 feet actual area: 225 square feet area of scale drawing scale and actual area scale drawing area: 3 square inches arrowright scale drawing area: 8 square inches arrowright scale drawing area: 4 square inches arrowright scale drawing area: 9 square inches arrowright

What is the perimeter of an equilateral triangle if each side is (x+3)?
