Answer:
15x + 9
Step-by-step explanation:
9(3x + 8) – 3(4x + 21)
Multiply
27x + 72 - 12x - 63
Combined like terms
27x - 12x = 15x 72 - 63 = 9
15x + 9
Answer:
The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin
Step-by-step explanation:
Given
Cost of coat in London = £60
Cost of coat in Dublin = €105.60
In order to find where the coat is cheaper, the price should be in same unit
It is also given that
£1 = €1.65
so,
Price of coat in Euro will be:

So the price of coat in London is 99 Euros
Comparing both the prices we see that
Price in London < Price in Dublin
99 < 105.60
The difference in price is:

Hence,
The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin
You would do 3 times 5 mines 5 which equals 10 and the you would do 5x12

Answer:
The Multiplication equation to find the number of hours taken to travel the distance is
.
It will taken <u>15 hours</u> by Russian ice breaker to travel a distance of 82.5 km through the ice.
Step-by-step explanation:
Given:
Thickness of the ice = 2.3 m
Speed while moving forward = 5.5 km/h
Distance to travel through the ice = 82.5 km
We need to write and solve the multiplication equation to find the number of hours taken to travel the distance.
Solution:
Let the number of hours taken to travel the distance be 'x'.
Now We know that;
By Distance formula;
Distance traveled is equal to Speed while moving forward multiplied by the number of hours taken to travel the distance.
framing in equation form we get;

Hence The Multiplication equation to find the number of hours taken to travel the distance is 
On Solving above equation we get;
Dividing both side by 5.5 we get;

Hence It will taken <u>15 hours</u> by Russian ice breaker to travel a distance of 82.5 km through the ice.
