Answer:
D and E because they are bigger than 28. C is 28 but there isn't a greater OR EQUAL sign next to it
Answer:
It means the system does not have a solution
Step-by-step explanation:
The answer is A) left 3, up 2
A) If you cut off half the peaks (3.5 ft down from the top), they will just fill the valleys making a rectangle 18.5 ft by 30 ft. The area is the product of these dimensions.
A = (18.5 ft)*(30 ft) = 555 ft²
b) To determine the number of quarts of paint required, divide this number by 90 ft². Since you cannot buy a partial quart, if there is any remainder, use the next higher integer number of quarts.
555/90 ≈ 6.2 so Pat should buy 7 quarts of paint.
