$$
Annie's backpack is 18.2 lb and Estella's backpack is 16.75 lb.
To find out how much heavier Annie's backpack is, we can subtract Estella's backpack weight from Annie's backpack weight:
18.2 lb - 16.75 lb = 1.45 lb
Therefore, Annie's backpack is 1.45 lb heavier than Estella's backpack.
Jolie started to workout at the gym. Over the last three days they walked on the treadmill 2.32 miles, 1.86 miles, and 1.59 miles. Jolie’s weekly goal is 12 miles. How many more miles do they need to walk this week to meet their goal?(1 point)
miles
To find out how many more miles Jolie needs to walk to meet their goal, we need to add up the distances they have already walked and subtract it from their weekly goal.
Distance walked in 3 days = 2.32 miles + 1.86 miles + 1.59 miles = 5.77 miles
Miles remaining to meet the goal = Weekly goal - Distance walked in 3 days = 12 miles - 5.77 miles = 6.23 miles
Therefore, Jolie needs to walk 6.23 more miles to meet their weekly goal.
Armando went grocery shopping. He needed to buy everything on his list for a dinner at his church. This required him to go to three different stores, where he spent $32.89, $55.69, and $49.52. He was given $175 to spend on groceries. How much did he have left after all three stores?(1 point)
$
To find out how much Armando has left after shopping at all three stores, we need to subtract the total amount spent from the amount he was given to spend.
Total amount spent = $32.89 + $55.69 + $49.52 = $138.10
Amount left = Amount given - Total amount spent = $175 - $138.10 = $36.90
Therefore, Armando has $36.90 left after shopping at all three stores.

To find out how many seconds separated the top two runners, we need to subtract Marileidy Paulino's time from Shaunae Miller-Uibo's time.
Difference in time = Shaunae Miller-Uibo's time - Marileidy Paulino's time
= 48.36 seconds - 49.2 seconds
Taking the difference, we get:
Difference in time = -0.84 seconds
Therefore, 0.84 seconds separated the top two runners.
Solve the following problem using addition and subtraction. Katie and Emily are growing bean plants in their scouting troop. Katie’s bean plant is 15.2 inches tall, and Emily’s is 12.9 inches tall. Their scout leader said that she expected the plants to be at least 13.5 inches by this time. How close are Katie and Emily to this goal?(1 point)

Both Katie and Emily met the goal.
Both Katie and Emily met the goal.
Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal.
Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal.
Both Katie and Emily did not meet the goal.
Both Katie and Emily did not meet the goal.
Katie is 0.6 inches over the goal, and Emily is 1.7 inches under the goal.
Katie is 0.6 inches over the goal, and Emily is 1.7 inches under the goal.
To find out how close Katie and Emily are to the goal of 13.5 inches, we need to determine the difference between each of their bean plants' heights and the goal height.
For Katie: Difference = Katie's bean plant height - Goal height = 15.2 inches - 13.5 inches = 1.7 inches over the goal.
For Emily: Difference = Emily's bean plant height - Goal height = 12.9 inches - 13.5 inches = 0.6 inches under the goal.
Therefore, Katie is 1.7 inches over the goal, and Emily is 0.6 inches under the goal.
