Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.
Y :!2!298-76-6-7-8-&-8-7-6
Equation:
500-30x=130+20x
Since you want to find when they are the same, you put an equal sign. Also, since one is gaining and the other is losing, you have an addition and subtraction sign.
Solution:
370= 50x
x=7.4
Answer:
After 7.4 years, the clubs will have the same members, which is 278 members.
Tell me if this helps!!
3x - y = 9
4x + y = 5
---------------add
7x = 14
x = 14/7
x = 2
3x - y = 9
3(2) - y = 9
6 - y = 9
-y = 9 - 6
-y = 3
y = -3
C. (2,-3) is a solution to the system of linear equations
Answer:
V = 13/2
Step-by-step explanation:
When finding volume you must know the formula on doing so.
<em>Volume = length × width × height</em>
length = 
--> 
width = -->
height = 
--> 
<u>mixed number --> fraction</u>
or
