-7
Step-by-step explanation:
Evaluate the expression for u=10. Subsitute u for 10 and substract it by 17. 10-17= -7
Your answer is -7
Answer:
Step-by-step explanation:
X is the missing number
Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.
<h3>How to form equation and solve ?</h3>
The fundraiser only have 3 prices for books which are $2, $5 and $10.
There were 6 more $5 books sold than $10 books sold.
Let
x = number of $10 book sold
Therefore,
number of $5 books sold = x + 6
There are 8 more $2 book sold than $10 book sold. Therefore,
number of $2 books sold = x + 8
A total of $250 was raised.
Therefore, the total amount sold forms the following equation:
10x + 5(x + 6) + 2(x + 8) = 250
10x + 5x + 30 + 2x + 16 = 250
17x = 250 - 30 - 16
17x = 204
x = 204 / 17
x = 12

Answer:
d = (5√53)t
Step-by-step explanation:
After 1 hour, A is 10 miles north of the port, and B is 35 miles east of the port. Since these directions are at right angles, the Pythagorean theorem can be used to find the distance between the ships:
d = √(10² +35²) = √(100 +1225) = √1325 = 5√53 . . . . miles
The distance between the ships is increasing this number of miles each hour, so the desired expression is ...
d = (5√53)t ≈ 36.4t
