a. or c.
Step-by-step explanation:
.18 21/5 27
18 10/ 5 12
Answer:
10 days to complete
Step-by-step explanation:
for mixed rate problems, the sum of each individual reciprocal rates equals the sum of the combined rate
i.e
we are given,
A's rate = 15 days to complete
Combined rate = 6 days to complete
B's rate = need to find
substituting' the given info into the equation above,
1/15 + 1/ (B's Rate) = 1/6
1 / (B's Rate) = 1/6 - 1/15 (convert right side to same denominator)
1 / (B's Rate) = 5/30 - 2/30
1 / (B's Rate) = 3/30
1 / (B's Rate) = 1/10 (taking reciprocal of both sides)
B's rate = 10 days to complete
The probability that Rebecka selects a terrier and Aaron selects a retriever is 10/121
<h3>How to determine the probability?</h3>
The distribution of the puppies is given as:
4 poodles, 5 terriers, and 2 retrievers
The probability of selecting a terrier is;
P(terrier) = 5/11
The probability of selecting a retriever is;
P(retriever) = 2/11
The required probability is
P = 5/11 * 2/11
Evaluate
P = 10/121
Hence, the probability that Rebecka selects a terrier and Aaron selects a retriever is 10/121

-(7x + 4)- 2x + 2 = 52
Distribute the negative sign:
-7x -4 - 2x + 2 = 52
Combine like terms:
-9x - 2 = 52
Add 2 to both sides:
-9x = 54
Divide by -9:
x = -6
Answer: x = -6
