Jeff can paint 28aquare feet every 15 minutes. angela can paint 115 aquare feet every hours. who can paint faster, and by how many square feet per hour?

Angela, by 3 ft² per hour

Step-by-step explanation:

Jeff can paint 4 times the area in 4 times the time, so

... (4×28 ft²)/(4×15 min) = 112 ft²/(60 min) = 112 ft²/h

Since 115 ft²/h is more than 112 ft²/h (by 3 ft²/h), Angela is the faster painter.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
