The ratio of the number of miles run to the number of miles biked is equivalent for each row in the table.

Mathematics

Shalnov [3]3 years ago

Answer:

Option C is correct.

A = 2\frac{3}{4} miles.

Step-by-step explanation:

Find the missing quantities in a ratio table where a total is given,

first determine the unit rate from the ratio of two given quantities and use it to find the missing quantities in each equivalent ratio.

Find the constant rate;

We can  use the row that gives both quantities, not the total.

\frac{7}{3\frac{1}{2} } = \frac{7}{\frac{7}{2} } =\frac{7 \times 2}{7} = 2

Now, we write the equation of relationship:

B'= 2R where B' is the distance Biked (in miles) and R is the distance Run(miles)

To find the missing value of A;

using above relationship;

5\frac{1}{2} =2 \times A

\frac{11}{2} = 2A

Divide both sides by 2 we get;

\frac{11}{2 \times 2} =A

Simplify:

A =\frac{11}{4} = 2\frac{3}{4} miles.

Similarly; find the missing value of B;

Using above relationship;

B = 2 \times 2\frac{1}{8} = 2 \times \frac{17}{8}

Simplify:

B = \frac{17}{4} =4\frac{1}{4}

Therefore, the value of A=2\frac{3}{4} miles.

Examine this system of linear<br> equations.<br> y – 3x=-2,<br> y = 4
Verdich [7]

Answer:

2, 4

Step-by-step explanation:

Ok so for this you have to substitute. y=4 so you put a 4 where the y is. This becomes

4 - 3x = -2 We can already rule out (2,2) and (4,2) Why? Because the y is not a 4. So it’s gonna be either (0,4) or (2,4). Now, we have to find x. We have to isolate it. You do this by subtracting 4 from both sides.

4 - 4 - 3x = -2 - 4 Now Simplify

-3x = -6 Why -6? Because you can’t subtract a positive from a negative so it becomes -2 + -4. Since they are both negatives, you just add them together, then put the negative sign.

Now divide -3 from both sides. Which becomes

x = 2

What is the minimum number of fish in the pond? (Hint: You caught 100 fish both days, but you caught 3 of the same fish twice.)
nevsk [136]

Answer:

197

Step-by-step explanation:

So, if you catch 100 fish on both days, that means that you have caught 200 fish. 100 on one day and 100 on the next. But, since you've caught 3 fish twice, that means that three out of 200 fish are the same and cannot be counted as new fish. So 3 from 200 is 197 fish. Hope this helped!

Day 1: 100 (3 tagged)

Day 2: 97 (3 tagged)

100+97=197

or

Day 1: 100 (3 tagged)

Day 2: 100 (3 tagged)

100+100= 200

200-3=197

Answer, 197 fish.
