Answer:

z=3

Step-by-step explanation:

Add 3z and 2z

5z-5=25-5z

Add 5z on both sides to eliminate the -5z on the RHS

10z-5=25

Add 5 on both sides to eliminate the -5 on the LHS

10z=30

Divide by 10

z=3

Hope this helps!

kaheart [24]

Given :

A restaurant had 3 full boxes of spoons and 4/6 of a box.

Each full box weighed 2 kilograms .

To Find :

The combined weight of the boxes the restaurant has.

Solution :

Mass of 1 box is 2 kg .

So , mass of 4/6 of a box is 4/3 kg .

Total mass :

M=3\times \text{Mass of one full box }+ \text{Mass of 4/6 of a box}\\\\M=(3\times 2) + \dfrac{4}{3}\\\\M=7.33\ kg

Therefore ,  the combined weight of the boxes the restaurant has is 7.33 kg.

Hence , this is the required solution .
