Answer:
55
Step-by-step explanation:
Factors for 605: 1, 5, 11, 55, 121, and 605
Factors for 55: 1, 5, 11, and 55
So the highest common factor they have is 55.
HCF = 55
Complete question :
Sweets are sold loose, or pre-packed in 120g bags.The 120g bags are £1.49 each.The loose sweets are £0.89 for 100g.
By calculating the price per gram, determine which is better value.
Answer:
100 g bag
Step-by-step explanation:
For the 120g bag:
Price per gram :
Price / Numbe of gram
1.49 / 120 = 0.0124 gram per bag
For the 100 g bag :
0.89 / 100
= $0.0089per gram
Since $0.0089 is < $0.0124
Then the 100g bag is of better value
Answer:
simple, divide the number by two, round as needed. 6=3x as normal, 5=2.5x as nromal, etc.
Step-by-step explanation:
(-6x-2)-(-3x+5)= -24x+14
-6x-2+3x-5=-24x+14
-3x-7=24x+14

Answer:
Below in bold letters.
Step-by-step explanation:
a. y = 3x - 1.
The equation of the perpendicular line will have slope -1/ 3.
So we have the equation y - y1 = -1/3(x - x1) where (x1, y1) is a point on this perpendicular line.
As the line passes through (0,0):
y - 0 = 1/3(x - 0)
y = -1/3x is the required equation.
If x,4 is on the line then x is found by substituting for y:
4 = -1/3 x
x = 4 / -1/3
x = 4*-3 = -12.
b. y = 1/4x + 2
By the same method as in part a:
the equation is y = -4x.
x = 4 / -4 = -1.
