Answer:

The Large Box Weighs 18 kg, and the small box weighs 6.5 kg

Step-by-step explanation:

Let a= the weight in kg of a large box

Let b= the weight in kg of a small box

Multiply both sides of (1)  by 4 and subtract (2) from (1)

1. 20a+8b=412

2. -3a-8b= -106

17a=306

a=18

and

5*8+2b=103

90+2b=103

2b=13

b=6.5

NEED HELP:
PSYCHO15rus [73]

Answer:

The radius is approx. 7.5

Let me know if it helps or if I got anything wrong!

Step-by-step explanation:

To find the circumference, you need to multiply the diameter by pi (3.14)

And for vice versa, just divide.

Since we don't know the diameter nor radius, we need to divide the Circumference (C) by pi (3.14)

47/3.14=14.968

Which is rounded up to 15.

We have now found the diameter.

We also know that the radius is half of the diameter

15/2=7.5
