Answer:
-1+5z, -25+20y, 4d+14, 2n-2, 40k+8, 8b+5, -9+22p
Step-by-step explanation:
1) -4+7z+3-2z
-1+5z
2) 15+4(5y-10)
15+20y-40
-25+20y
3) 2d+17-3-2d+4d
4d+14
4) 12n-8-2n+10-4
2n-2
5) 8(2k+1+3k)
16k+8+24k
40k+8
5) 4(2b+2)-3
8b+8-3
8b+5
6) -4+8p-6p-5+20p
-9+22p
Using y=Mx+b, the answer is y=10x-4.
Letter d is s geometric sequence. You multiply or divide by the same number (r), common ratio to be a geometric sequence
I think it is y=5x. Because k=y/x. 10/2=5. y=5x.
Answer:
5, 20, 35
Step-by-step explanation:
Let x represent the first number. The given relation is ...
x + 4x + (4x+15) = 60
9x = 45 . . . simplify, subtract 15
x = 5 . . . . . .divide by 9
The three numbers are 5, 20, 35.
