First we would change the fractions into decimals and compare them. That way it would be easy to solve when needed.

1/2=0.50
5/8=0.625
1/8=0.125
   
Now we can see that 1/8 (0.125) is the smallest, followed by 1/2 (0.50), and 5/8 the largest. Now we can match the sizes with the insects.

Since the tiger beetle is the largest we will place that with the length of 5/8 since that is the largest.

The carpenter ant is second largest so it would be matched with 1/2

The aphid is the smallest so that would be with 1/8 as the smallest

*Hope that helped :D*

10. Jack and Dion sold a total of 33 appliances for their store. Dion sold 3 less than twice as
podryga [215]

Let x = amount of appliances Jack sold

Let y = amount of appliances Dion sold.

We need to construct a system of equations to solve this problem

33 = x + y

y = 2x - 3.

Let's solve this system of equations by substitution.

33 = x + (2x - 3). Combine like terms.

33 = 3x - 3. Add 3 to both sides.

36 = 3x. Divide both sides by 3

12 = x. Plug this value into one of our original equations.

33 = 12 + y.  Subtract 12 from both sides

y = 21

Jack sold 12 appliances and Dion sold 21 appliances.

two airplanes leave an airport at the same time and travel in opposite directions. one plane travels 70km/h slower than the othe
Nitella [24]

Answer:

<em>The speeds are 877 km/h and 947 km/h.</em>

Step-by-step explanation:

The slower plane travels at x km/h. The faster plane travels at (x + 70) km/h. The speed of separation is the sum of the speeds, (2x + 70) km/h.

They are 5472 km after 3 hours of travel.

speed = distance/time

2x + 70 = 5472/3

2x + 70 = 1824

2x = 1754

x = 877

The slower plane travels at 877 km/h.

x + 70 = 877 + 70 = 947

The faster plane travels at 947 km/h.
