Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.
Simplifying the expression (x - 2y) + (3x + 4y).
Work:
(x - 2y) + (3x + 4y)
Combine like terms.
x + 3x = 4x
-2y + 4y = 2y
Reform the expression.
4x + 2y
Simplified Expression: 4x + 2y.
Answer:
470 cm
Step-by-step explanation:
4.7 x 100 = 470
X=2y because whenever x goes up one, y goes up two
Answer:
4
Step-by-step explanation:
To find the distance between two points, we subtract the x - x coordinates and y - y coordinates.
-1 - (-1) = 0
-8 - (-4) = -4
There was only a change in the y coordinates, so we will only account for this.
The distance between the points is four units.
