The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
Answer: n = 63
Step-by-step explanation:
1260/20 = n/1
63/1 = n/1
n = 63
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.
