Someone will be glad to check your answers.
Well the fist question i got D and the second answer i got C i am not sure if i am right
Can u help check my answers? I am not sure if i got it right.
Your first answer is right.
C can't be right because 3/8 * 3/1 = 9/8 = 1 1/8. I would expect to get about 8 burgers.
To solve the first problem, we need to simplify the expression 5 (11 + 19).
Step 1: Begin by evaluating the addition inside the parentheses: 11 + 19 = 30.
Step 2: Multiply the result by 5: 5 x 30 = 150.
Therefore, the total amount the store received is $150.
From the given options, the expression that is equal to $150 is:
B) 5 x 11 + 19.
For the second problem, we need to find the expression that shows how many 3/8 pound hamburger patties can be made from 4 1/3 pounds of ground beef.
To find the answer, we need to divide 4 1/3 pounds of ground beef by 3/8 pound.
Step 1: Convert 4 1/3 to an improper fraction: (4 x 3 + 1) / 3 = 13/3.
Step 2: Divide 13/3 by 3/8: (13/3) ÷ (3/8).
Step 3: To divide fractions, multiply the first fraction by the reciprocal of the second fraction: (13/3) x (8/3).
Step 4: Multiply the numerators and denominators: (13 x 8) / (3 x 3).
Therefore, the expression that shows how many 3/8 pound hamburger patties can be made from 4 1/3 pounds of ground beef is:
A) 4 1/3 × 3/8.
