1. c + 3/10 = 31/70
2. w + 6 1/2 = 10 1/6

Answers

Answer 1
Answer:

Answer:

1. c = 1/7

2. w = 11/3

Step-by-step explanation:

1. c + 3/10 = 31/70

move 3/10 to the opposite to get c, we can do this by subtracting 3/10 from both sides

c = 31/70 - 3/10

c = 1/7

2. w + 6 1/2 = 10 1/6

same thing, move 6 1/2 by subtracting it from both sides

w = 10 1/6 - 6 1/2

w = 11/3

Answer 2
Answer: 1. C=1/7
Work:
You have to subtract 3/10 on both sides.
2. -4/3
You have to subtract 6 1/2 on both sides.

24 multiplied with 12 is 288 and dividing that with 10656 equal up to 37 days of food supply.

If you know the rate of a water leak in gallons per hour, how can you find the number of hours it takes for 1 gallon to leak out?

Answers

You will need to take the rate it's leaking out at, and figure out how many times that unit goes into one full gallon. Then you will need to multiply your answer by the time given in the rate.

.5 gallon goes into 1 full gallon twice. And 2 x 2 = 4

So figure it out.
You will need to take the rate it's leaking out at, and figure out how many times that unit goes into one full gallon. Then you will need to multiply your answer by the time given in the rate.

Example: If the rate is .5 gallon per 1 hour, then we already know that it will take 2 hours...but to calculate it, we will take the .5 gallon and see how many times it goes into a full gallon, Its 2. Now multiply by 1 (since the rate was .5 gallon per 1 hour). So the answer is in fact 2.

Example 2: If the rate was .5 gallon every 2 hours, we will use the same method. If we think about it, we probably already know it will be 4 hours...but lets calculate!

.5 gallon goes into 1 full gallon twice. And 2 x 2 = 4

Determine the domain and range of the function F(x)=(x-3) {exponent of 2 behind the parentheses}

Answers

That's a parabola. Inside the parenthesis the x-3 affects the placement on the x axis. since is subtracting you move the vertex 3 to the right(because its backwards like that) There is no limit to the x, as it will slowly mom out forever even when its so steep that in reality you dont care, so domain is infinite or all real numbers. the parabola is positive so it moves up forever, but it never goes below its vertex on the x axis. 
Domain=all real numbers
Range= all real numbers>or = 0
