The sequence for the nth term is (6n+6)+1
Hence the 77th term would be
( 6(77) + 6 ) + 1
=469
4x + 2y = 5y + 7
4x - 3y = 7
4x - 3y = 7
8x + 3y = 41
----------------add
12x = 48
x = 48/12
x = 4
8x + 3y = 41
8(4) + 3y = 41
32 + 3y = 41
3y = 41 - 32
3y = 9
y = 9/3
y = 3
solution is (4,3)
Answer:$6250
Step-by-step explanation:
selling price(sp)=12000
Original price(op)=?
sp+500=2 x op
12000+500=2 x op
12500=2 x op
Divide both sides by 2
12500/2=(2 x op)/2
6250=op
Therefore original price is $6250
14.6 x 3.8 = 55.48
Just multiply the numbers
2974 - 3364 = -390
Subtract the number and it’ll go into the negatives
120.08 + 24 = 144.08
Just add the numbers.
It’s very simple
Ex. 20 + 24= 44 (144.08)
Try using photo math it helps a lot!
