Answer:
p=74
a=60
Step-by-step explanation:
Answer:
x = 10
y = 25
Step-by-step explanation:
if you add the equations as they are then the 'y-term' is eliminated:
60x = 600
x = 10
substitute x=10 to find value of 'y':
40(10) + 4y = 500
400 + 4y = 500
4y = 100
y = 25
Check:
20(10) - 4(25) should equal 100
200 - 100 = 100
100 = 100

Answer:
Step-by-step explanation:
hello :
the nth term of an arithmetic sequence is :
An =An+(n-p)d ....a common difference is : d
let : n=15 and p=1 d= 4 A15 =43
A15 = A1 + (15-1)(4)
43= A1 +56
A1= 43-56 = - 13
