Mkey [24]

Calculating the cost of 4.25 kilogram(kg) is £2.38, by multiplying it by 4.25 kg by 1 kg.

<h3>Cost</h3>

Costs are the expenses incurred in the manufacture, marketing, or preparation of a good or asset for regular use. In other terms, it's the cost incurred to produce a good, buy inventories, sell goods, or prepare equipment for use in a commercial activity.

Given,

2.5 kg cost  £1.40 i.e,

2.5 kg = £1.40

For 1 kg= \frac{1.40}{2.5}

= £0.56

To find the cost of 4.25 kg:

Then,

1 kg = £0.56

4.25 kg = 0.56 x 4.25

= £2.38

£2.38 is the cost of 4.25kg after calculating it.

When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?
miv72 [106K]
-\frac{1}{5}(x-25) = 7       multiply 5 to both sides first
-(x-25) = 35                                     then expand the brackets
-x+25=35                                        make x the subject now;
-x=10
x= -10
