C=3.14d solve for d

Answers

Answer 1
Answer: you would divide both sides by 3.14, to get d by itself.  so c/3.14=d

Answer 2
Answer: 3.14d=c\ \ \ \ |divide\ both\ sides\ by\ 3.14\n\nd=(c)/(3.14)\n\nd=(100c)/(314)\n\nd=(50c)/(157)

1) While your family is visiting Deep Creek Lake, you and your brother decide to go boating. Thepark rangers require a $25.00 down payment to rent a canoe and a rental fee of $10.00 per hour.

a) Write a linear function to model this scenario.

Answers

Answer:

Y=10x+25

Step-by-step explanation:

Hey so let’s take the number of hours we go boating as “x” and the TOTAL cost of this whole trip as “y”.

So obviously y would equal everything else so we can write

Y=

Next, it says we rent a canoe for $10 an hour. That means we would have to multiply 10 and x to find the cost of the rent.

So

Y=10x

Finally, it says we paid a registration fee of $25. This 25 is not affected by the number of hours or anything else. It is a fixed amount so we can represent it as

Y=10x+25

Hope this helps!

–12x + 9 = –15x solve for x

Answers

Answer:

hi there!

the correct answer to question is: x=-3

Step-by-step explanation:

you move -12x to the other side by adding it on both sides to get: -3x=9 then you divide -3 on both sides to get x=-3

-12x +9 = -15x
+15x +15x

3x +9 = 0
-9 -9

3x = -9

3

x= -3

3x = 81? A. adittion B. subtraction C. multiplication D. division

Answers

3 × x = 81

This is a multiplication problem. To solve for x you must divide 81 by 3.

So your answer is D. division.

its D) Division because you are going to divide both sides by 3 to get x by its self
