X+y=57
y=x+15
x+x+15=57
2x=42
x=21
y=21+15
y=36
How do you want this solved?
Answer:
c. 130
Step-by-step explanation:
Let call B the quantity of voters who voted yes for both propositions.
From the question we know that twice as many voters voted "yes" for R as for S, that can be written as the following equation:
R+B=2(S+B)
Where R is the number who voted "yes" for R but "no2 for S and S is the number who voted "yes" for S but "no" for R.
Replacing R by 750 and S by 310 and solving for B, we get:
750+B=2(310+B)
750+B=620+2B
2B-B=750-620
B=130
So, 130 voters voted yes for both propositions
Answer:
A.
Step-by-step explanation:
y=mx + b where m is the slope and b is the y-intercept. So substituting 4/5 for m and 5 for b, you get answer A.
Answer:
0.25 Converges
Step-by-step explanation:
First, we need to expand our series so that we get the following:

We can then use the series ratio test on each term. (L < 1 = absolutely convergent)

=
⇒ converges


⇒ converges
converges + converges
= converges
