Ans: Let it started from zero. And it lasts 6 yards means that -6 represents a loss of 6 yards.
After that, the team lost 5 yards. So, -11 will represent a loss of 5 yards
<span>The team after gaining 12 yards on next day will not be at their starting position. Instead, it will be at ‘1yard’ more than the starting position. The number will be ‘1’ which will represent the position of the team after gaining 12 yards.</span>
So,
1/4(3c + 5) + -1/2(2c + 3) = 1/2
First, we distribute to get rid of the parentheses. (PEMDAS)
3/4c + 1 1/4 - c - 1 1/2 = 1/2
Now, we collect like terms.
-1/4c - 1/4 = 1/2
Add 1/4 to both sides.
-1/4c = 3/4
Now, multiply by the reciprocal (-4/1).
c = -3
Check your answer.
1/4(3[-3] + 5) + -1/2(2[-3] + 3) = 1/2
1/4(-9 + 5) + -1/2(-6 + 3) = 1/2
-2 1/4 + 1 1/4 + 3 - 1 1/2 = 1/2
-1 + 1 1/12 = 1/2
1/2 = 1/2
Answer:
an = 7 + 5n
Step-by-step explanation:
First we know that for each number of days rented the cost increase by 5 so we get an - (?) + 5n.
We also know the first number is 12 for 1 day, so for 0 days, or the starter cost, is 7. We get this by subtracting 5 from 12.
Hence the answer an = 7 + 5n
Answer:
10
Step-by-step explanation:
divide each side by -4
5x-1=-49
5x=50
x=10
Answer: The conclusion is that all samples of the same size between 18% to 20% indicate that people living in a certain region use sunscreen regularly when going outdoors.
Explanation: Given percentage from the recent survey, the possible range is calculated as below:
All possible range : (19% ± 1% ) = (18%, 20%)
