Answer:
D
Step-by-step explanation:
change minutes to degrees
60minutes=1degree
47 mutes=?
47/60=0.78333333°
Add to 52°
52° + 0.78333333°
52.78333333°
so sin 52.7833 =0.7963540136
5n - 10 is the way to write the expression you wrote in English above.
It does not mean much until we set it equal to something.
For example:
The difference of five times a number n and 10 is 25.
Now
5n - 10 = 25
by subtracting 10 from each side we get 5n=35 and then if we divide both sides by 5, we get n=7.

Answer:
The larger number is 12 and the smaller number is 9
Step-by-step explanation:
Let us first deal with the first sentence of this word problem.
Let's call the larger number L
and the smaller number S
.
We know from the first sentence:
3
L =
4
S
We know from the second sentence:
L+S =
21
Let's solve this second equation for
L-
L+S =
21
-
L
S =
21
-
L
Now we can substitute 21
-
L for S in the first equation and solve for L :
3L = 4 (21
-
L)
3L + 4L = 84 - 4L + 4L
7L = 84
7L/7 = 84/7
L = 12
Next we can substitute 12 for L in the solution to the second equation:
s = 21 - 12
s = 9
her total estimate for the repairs= $210
Here, we add the cost of all repairs.
The costs of repairs
Wheel alignment =$110
Transmission fluid flush=$75
Cabin air filter=$23
Total repairs =$110+$75+$23 =$208
Rounding to the nearest $10 becomes $210
