Answer:
6.5 hours
Step-by-step explanation:
First try to find the rate he can paint per hour
375 ÷ 3 = 125 ft^2 per hour
Then try to find how long it should take it for him to paint 812.5 sq ft
812.5 ÷ 125 = 6.5 hours
First add like terms in this case 1+7=8. Then then divide. 2x/8= 4. X=4
Seven has the greatest value as a digit, but 1, 000 has the greatest standard form value.
