Answer:
47, 40, 33, 26 are the first four terms of the sequence.
Step-by-step explanation:
Expression representing the sequence is,

where n = number of term in the sequence
For n = 1,

= 47
For n = 2,

= 47 - 7
= 40
For n = 3,
= 47 - 7(3 -1)
= 47 - 14
= 33
For n = 4,

= 47 - 21
= 26
Therefore, first four terms of the sequence are 47, 40, 33 and 26.
Answer:
1.5
Step-by-step explanation:
Vertical angles are congruent so:
7x=8x-12
Subtract 7x from both sides:
0=8x-12
Add 12 to both sides:
8x=12
Divide both sides by 8:
x=1.5 or
x= 3/2
Answer:
Aratati ca numarul A=ab+ba-aa-bb este patrat perfect ( deasupra la ab ba aa bb este o linie orizontala) b)determinati nr ab astfel incat B=ab+5ab-126 sa fie patrat perfect ( deasupra la ab 5ab este o linie orizontala) c) aratati ca 25=3²+4² si 625=7²+24²

Actually Welcome to the Concept of the Parallel lines.
To make them parallel ,just equate them.
5x = 3x + 60
===> 5x - 3x = 60
===> 2x = 60
.hence, x = 30
====> x = 30
Answer:
2x + 3y=-10 is incorrect (I think)
When you mulitply something with no negative you get something with no negative
