Answer:
a)Number of terms =15
Value of sum =
(b)Number of terms =6
Value of sum
Step-by-step explanation:
A.
nth term,
a=5, r=
Simce the bases are the same, the powers are equal.
n-1=14
n=14+1=15
Number of terms =
15
Value of sum =
B.
nth term,
a=,
Simce the bases are the same, the powers are equal.
4+n-1=9
n=9+1-4=6
Number of terms =
6
Value of sum
NOTE: For the sum, we desire an expression that gives the exact value, rather than entering an approximation
Answer:
<em>x</em> = 9.
Step-by-step explanation:
If you meant (x + 13) = 24, then we first must subtract 24 by 13.
24 - 13 = 9
Now, check your work by replacing the "x" with 9.
(9+ 13) = 24
24 = 24 <----- This is a true statement.
Therefore, <em>x</em> = 9.
Hope this helps! :D
<em>Answer: 24 </em>
<em>Step-by-step explanation:</em>
Equation: (1/3)x + 4 + 12 = x
Equation: (1/3)x + 16 = x
MULTIPLY EVERYTHING WITH 3
1/3 times 3 = x 16 times 3 = 48 x times 3 = 3x
Equation: x + 48 = 3x MINUS THE "X" BY 3X = 2X
Equation: 2x = 48 OR x = 24
CHECK THE EQUATION:
Sister: 8 Brother: 4 Herself: 12
8 + 4 + 12 = 24
is equal to
