(100 points) find the cost of each treat
Anna71 [15]

Answer:

icecream = $2.99

donut = $1.19

creamcake = $4.99

Step-by-step explanation:

The picture shows $7.17 for 2 x ice-cream and 1 donut

We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99

9.17- 4.99=4.18

=5.37-4.18 =1.19

we can then fill out the boxes.

1.19 +1.19 = 2.38 = 5.37-2.38= £2.99

2.99 +2.99 +1.19 = $7.17

We can see total first two rows = $12.56

2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 45 minutes? In 1 hour?
mina [271]

Answer:

33.75 miles in 45 minutes,

45 miles in an hour

Step-by-step explanation:

45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,

                    1 3/4= 7/4 ---> 7/4*3=5.25

car travels 5.25 miles for every 7 minutes,

45/7*5.25= 33.75 miles

1 hour (60 minutes):

using that the car travels 5.25 miles for every 7 minutes,

60/7*5.25= 45 miles

Hope that makes sense!
