Answer:
A line has one dimension because it is made up of all points that extend infinitely in either direction.
Step-by-step explanation:
The smallest would be 400,000 and the largest would be the same because 0 can't round up or down
So,
We'll just use A to represent both Jan and Mya's miles, since they ran the same number.
We have the equations:
1. Jan (J) = Mya (M)
2. Sara (S) = M - 8
3. 2A + S = 64
J = M
S = M - 8
We'll just use A to represent both J and M.
S = M - 8
We'll use Elimination by Substitution.
2A + A - 8 = 64
Collect Like Terms
3A - 8 = 64
Add 8 to both sides
3A = 72
Divide both sides by 3
A = 24
Since
A = J
and
A = M
and
J = M
then
J = 24
M = 24
Substitute
S = 24 - 8
S = 16
Check
24 + 24 + 16 = 64
64 = 64 This checks.
So,
J = 24
M = 24
S = 16
Answer: £5.39
Step-by-step explanation:
500g strawberries = 4.10
100 g = 0.82
300g = 2.46
400g raspberries = 7.46 - 2.46 = 5.00
100g = 1.25
300g = 3.75
200g strawberries = 0.82 * 2 = 1.64
3.75 + 1.64 = 5.39
