Mrs eaves bought 5lb 15 oz of apples and 8lb 8oz of oranges. How many more ounces of oranges did she buy than apples!

What is the value of x? Is it 19, 31, 38 or 62

Find the solution of 7x = 35, and verify your solution using substitution. A. x = 245; 7 (35) = 245, 245 = 245 B. x = 6; 7 (6) = 35, 35 = 35 C. x = 5; 7 (5) = 35, 35 = 35 D. x = - 5; 7 (-5) = 35, - 35 = - 35
