Brainiliest if u answer both 1.Bella brought stickers to give to 12 of her friends. Each friend received 4 stickers. How many stickers did she bring to school?
2.ierra walks her dog Pepper twice a day. Her evening walk is two and a half times as far as her morning walk. At the end of the week she tells her mom,
I walked Pepper for 30 miles this week!
How long is her morning walk if there are 7 days in the week?

1. 48 stickers 2. 1.2 miles

Step-by-step explanation:

1. 12x4=48 stickers. 2. If we let w denote the length of the morning walk, Sierra walks w+2.5w or 3.5w miles each day. At the end of the week she has walked 7 times as far and she said that this was 30 miles. Solving the equation

24.5w=30,

we have w=30/24.5≈1.2 miles. Therefore the distance of Sierra's morning walk is about 1.2 miles

Solution: Using a diagram

We can illustrate the solution to this problem with a tape diagram. If we let one box be the morning walk, then the evening walk is 2.5 boxes. The total distance Sierra walks in one day is represented by 3.5 boxes. Instead of talking about the number of boxes, we can choose a variable to represent the value or length of each box, say w.

Since Sierra walks every day of the week, the total distance walked is 7 times as long. Therefore, we have the total distance walked during the week is 7(3.5w)=24.5w. We know that Sierra walks a total distance of 30 miles, so we have 24.5w=30 miles. We can use another diagram to illustrate the total distance with 24.5 boxes.

Dividing both sides of the equation 24.5w=30 by 24.5 allows us to find w, and we have

w=30/24.5≈1.2.

Therefore, Sierra's morning walk is about 1.2 miles.
