Answer:
Step-by-step explanation:
Hello!
To solve for x, we have to first isolate the variable.
<h3>Solve for x</h3>
The value of x is .
The surface
can be parameterized in cylindrical coordinates using
where
and
. The surface integral is then equivalent to
Emily can rake 1/5 of the lawn in an hr.
Andrew can rake 1/8 of the lawn in an hr.
Together, they rake 1 yardful. x represents time in hours.
(1/5)x+ (1/8)x= 1
Multiply all values by 40
8x+5x=40
13x=40
x= 40/13
x=3.0769...
Final answer: 3 hours
The statement is represented as 2(c- 5). Option D
<h3>
What are algebraic expressions?</h3>
Algebraic expressions are expressions consisting of variables, terms, factors, and constants.
They are also made up of mathematical operations such as addition, bracket, subtraction, division, multiplication, etc
From the information given, we have;
- total cost of 2 dance tickets
- price of c for each, less a one-time $5 discount
Expressed as;
2(c- 5)
Thus, the statement is represented as 2(c- 5). Option D

We can use proportion here. As we know, cost of a rocker is now 80% of original.
So:
