If a roasting is 600mm x 500mm how many 25cm cake time will fit on it?
nydimaria [60]
So assuming that 25cm is 25 square cm because you cannot have a 2 dimentional cake so

600mm by 500mm
to find the area, multiply legnth by width

mm=milimeters
cm=centimeters
this is in mm so
1cm=10mm
1mm=1/10cm
to convert from mm to cm, you divide by 10
we must divide by 10 first
legnth =600mm
600/10=60cm
legnth=60cm

width=500mm
500/10=50cm
width=50cm

area=60 times 50=3000 square cm or cm^2
so 3000 is the area
25 is the area of each cake
divide 3000 into 25 and find how many cakes will fit

3000/25=120

120 cakes will fit

Follow the steps to solve for the variable in this two-step equation:
lesya692 [45]

The solution of the equation is x = 2

Step-by-step explanation:

The original equation is

5x-10 = 0

We solve it using the following steps:

1) We apply the addition property of equality: by adding the same factor on both sides of the equation, the equation does not change.

In this case, we add +10 on both sides, and we get:

5x-10+10=0+10\\5x=10

2) We apply the division property of equality: by dividing both sides of the equation by the same number (different from zero), the equation does not  change.

In this case, we divide both sides of the equation by 5, and we get:

\frac{5x}{5}=\frac{10}{5}\\x=2

Therefore, the solution of the equation is x=2.
