1.
3n + 5 = 6
3n = 6 - 5
3n = 1
n = 1/3
2.
4 + 5x = 1
5x = 1 - 4
5x = -3
x = -3/5
3.
4y - 15 = -10
4y = -10 + 15
4y = 5
y = 5/4
4.
3 - 4d = 13
-4d = 13 - 3
-4d = 10
d = -10/4
d = -5/2
5.
8 = 9x - 7
8 + 7 = 9x
15 = 9x
15/9 = x
5/3 = x
hope this helped, God bless!
<span>Let f(n) = 2n + 5. Then we must simply calculate (f1), f(2), ..., (f12). And we have that f(1) = 2*1 + 5 <=> f(1) = 7; f(2) = 2*2 + 5 <=> f(2) = 9; f(3) = 2*3 + 5 <=> f(3) = 11. And so on. It's easy to see that the rest of the results will be 13, 15, 17, 19, 21 and so on. So the summation will be S = 7 + 9 + 11 +... + 29 <=> S = 216</span>
Answer:
D because it costs less for 7 hours
Answer:
The answer is B.
Step-by-step explanation:
So, there are 46,000 seats for a baseball game and 49,442 attended. You need to subtract 46,000 from 49,442 to get the answer that is 3,442.
Answer:
quarts
Step-by-step explanation:
Total amount of drinks = 
+ 
You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.
+ = 
+ 
Now we can directly add them together while keeping the denominator the same.
+ = quarts
