Mathematics

forsale [732]3 years ago
6 0

Answer:

11

Step-by-step explanation:

Making the appropriate substitutions, we get

3/7 r + 5/8 s  =>  3/7 (14) + 5/8 (8).

Notice how this can reduced:

                             3(14)            5(8)

                           ----------- +     ---------   =   6 + 5 = 11

                                  7                8

If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Helga [31]
Hello!

To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.

y=4(0)-1
y=-1

So here, an ordered pair could be (0,-1)

We can try this again for different x-values.

y=4(1)-1
y=3

This gives us the ordered pair  (1,3)

y=4(100)-1
y=399

This would give us the ordered pair (100,399)

I hope this helps!

17. What's the difference between 1,968 and 3,000? Check your answer using inverse operations.
Georgia [21]
The difference between 1,968 and 3,000 is 1,038. You can check the answer using inverse operations by adding 1,038 and 1,968. If it gives 3,000 then the answer is right. 3, 000 - 1,968 = 1,038.

1,038 + 1,968 = 3,000
