Answer:
-2.1.
Step-by-step explanation:
−0.3 + (−1.8)
-0.3 - 1.8
= -2.1
Given:
The width of a kitchen is 4.2 metres.
Kitchen cupboard widths are 60 cm.
To find:
The number of kitchen cupboard that will fit in 4.2 metres.
Solution:
Let x be the number of kitchen cupboard that will fit in 4.2 metres.
Width of 1 cupboard = 60 cm
Width of x cupboards = 60x cm
We know that, 1 m = 100 cm.
Width of a kitchen = 4.2 metres
= 4.2×100 cm
= 420 cm
Now, the width of the x cupboards is equal to width of the kitchen.
![60x=420](https://tex.z-dn.net/?f=60x%3D420)
![x=\dfrac{420}{60}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B420%7D%7B60%7D)
![x=7](https://tex.z-dn.net/?f=x%3D7)
Therefore, the number of kitchen cupboard that will fit in 4.2 metres is 7.
Total paid equals 30 desks multiplied by (the original price minus $17).
p=original desk price
Equation: $2010= 30(p - $17)
To Solve:
2010=30(p-17)
Use distributive property to multiply
2010=(30*p) - (30*17)
2010= 30p - 510
Add 510 to both sides
2520= 30p
Divide both sides by 30
$84= p
Original desk price was $84.
Hope this helps! :)
