C. 1, all the other answers are negative
If u wanna go by a technical term then yes, it can. The positive and negative side of a number. 4 example, -5. It's absolute value is 5. Positive 5's absolute value is 5 as well.
Now if u don't wanna be technical and don't want to use negative numbers, then no, it cannot.
Answer:
23
Step-by-step explanation:
Answer:
Option A. 5
Step-by-step explanation:
From the question given above, the following data were obtained:
First term (a) = –3
Common ratio (r) = 6
Sum of series (Sₙ) = –4665
Number of term (n) =?
The number of terms in the series can be obtained as follow:
Sₙ = a[rⁿ – 1] / r – 1
–4665 = –3[6ⁿ – 1] / 6 – 1
–4665 = –3[6ⁿ – 1] / 5
Cross multiply
–4665 × 5 = –3[6ⁿ – 1]
–23325 = –3[6ⁿ – 1]
Divide both side by –3
–23325 / –3 = 6ⁿ – 1
7775 = 6ⁿ – 1
Collect like terms
7775 + 1 = 6ⁿ
7776 = 6ⁿ
Express 7776 in index form with 6 as the base
6⁵ = 6ⁿ
n = 5
Thus, the number of terms in the geometric series is 5.
Answer:
<em>a=$10</em>
<em>c=$3</em>
Step-by-step explanation:
Step one:
given data
let adults tickets be a
and child tickets be c
so
Roy's purchase
6a+2c=66------1
Elisa's purchase
5a+4c=62-------2
Hence, the system of equations
<em>6a+2c=66------1</em>
<em>5a+4c=62-------2</em>
<em>solving simultaneously</em>
<em>6a+2c=66------1 x2</em>
<em>5a+4c=62-------2 x1</em>
<em />
<em> 12a+4c=132</em>
<em> -5a+4c=62</em>
<em> 7a=70</em>
<em>divide both sides by 7</em>
<em>a=$10</em>
<em />
<em>put a=70 in 1</em>
<em>6(10)+2c=66------1</em>
<em>60+2c=66</em>
<em>2c=66-60</em>
<em>2c=6</em>
<em>c=$3</em>
