Answer:
£1.80/kg
Step-by-step explanation:
The total spent on apples and pears is £12.70, and this is the sum of the costs of the apples and the pears respectively:
£12.70 = (unit cost of apples)(2 kg) + (unit cost of pears)(7 kg), or
£12.70 = (unit cost of apples)(2 kg) + (£1.30/kg)(7 kg).
Solving for (unit cost of apples)(2 kg), we get £12.70 - (£1.30/kg)(7 kg), or:
(unit cost of apples)(2 kg) = £12.70 - £9.1 = £3.60
Solving for (unit cost of apples), we divide both sides by (2 kg), obtaining:
£3.60
(unit cost of apples) = ---------- = £1.80/kg
2 kg
Answer:
(1,5) is not a solution to the system of equations
Step-by-step explanation:
To find the point (1, 5) is a solution to the system of equations.
We look at the intersection of both graphs given
Both graphs intersects at (0,2)
Intersection of two graphs is the solution of system of equations
Two graphs intersects at (0,2). so (0,2) is the solution of system of equations
(1,5) is not a solution to the system of equations
Answer:
5
Step-by-step explanation:
from the attached diagram, we can see that
LN = MP
3x + 1 = 8x -4
8x-3x = 1 + 4
5x = 5
x = 1
hence
LN = 3x+ 1 = 3(1) + 1 = 4
NM = 4x-1 = 4(1) - 1= 3
hence by Pythagorean formula,
diagonal NP = diagonal LM = √( 3² + 4²) = √25 = 5
Answer: 8$
Step-by-step explanation:
Kaylie has 6 biscuits in total and she also has a cup of coffee so she spend 8 dollars in total.
The missing number of the area of the base is 36
because 324 divided by 9 is 36
