That means that, for example:
if your number is 49 the nearest whole number would be 50.
so by saying estimate the figure to the nearest whole number , they are basically saying find your nearest whole number.
-5= -5x-10
Plus 10 from both sides
5=-5x
X = -1
Answer:
The rule of the arithmetic sequence is 13 - 2n
The 30th term is -47
Step-by-step explanation:
∵ f(n) = 11 and g(n) = -2(n - 1) = -2n + 2
∴ f(n) + g(n) = 11 + -2n + 2 = 13 - 2n
Use n = 1 , 2 , 3 , 4 to check the type of the sequence
∵ n = 1 ⇒ 13 - 2(1) = 11
∵ n = 2 ⇒ 13 - 2(2) = 13 - 4 = 9
∵ n = 3 ⇒ 13 - 2(3) = 13 - 6 = 7
∵ n = 4 ⇒ 13 - 2(4) = 13 - 8 = 5
∵ 11 , 9 , 7 , 5 is an arithmetic sequence with difference -2
∴ The rule of the arithmetic sequence is 13 - 2n
∴ The 30th term = 13 - 2(30) = -47
Answer:
$16.74
Step-by-step explanation:
If the price has been reduced by 35%, it is 100% -35% = 65% of what it was.
0.65 × $25.75 = $16.7375 ≈ $16.74
You will pay $16.74 for the chips.
