Answer:

(a) 75 minutes

(b) 50 minutes

Step-by-step explanation:

Firstly, she has 750 books to label and she labels 10 books in a minute. Hence, the number of minutes it will take her will equal the number of books divided by the number of books labeled in a minute.

This will be 750/10 = 75 minutes

Secondly, we use the same approach here but the number of books she labeled in a minute is different. Hence we get 750/15 = 50 minutes.

Lastly, the relationship between her labeling speed and the number of minutes is shown as follows.

The speed has a unit of books/minute since it is a rate and this is equal to number of books labeled ÷ Time taken to label them

X+y=8 solve by substitution <br> and<br> Y=3x with substitution too

inna [77]

Answer:

x=2

Step-by-step explanation:

Convert the Y to 3x since we know that y=3x.

You would get x+3x=8.

Add the x and 3x to get 4x

Then, you would get 4x=8.

Divide by 4 on both sides to get x=2.

1) A bag contains six red marbles and eight blue marbles. You randomly pick a marble and then pick a second marble without retur

Elena-2011 [213]

Answer:

You would have 4 red marbles and 8 blue marbles since you didn't return the ones you took out to the bag.

Step-by-step explanation:

6 - 2 = 4

The 8 would stay the same

There for you would have 4 red marbles and 8 blue marbles left in the bag. Totalled you have 12 marbles in the bag and 2 out of the bag. (8 + 4 = 12)

Including the marbles in and out of the bag you have 14 marbles. The 12 inside the bag + the 2 outside of the bag = 14 marbles totalled.

Kiley, Jermaine, and Gunther are playing tug-of-war. Kiley and Jermaine are on the same side of the rope, and Gunther is on the

Naya [18.7K]

First we define a reference system.

Let's assume the horizontal axis as positive towards the right.

Suppose Kiley and Jermaine pull the rope to the left, while Gunther pulls the rope to the right.

The equilibrium equation is given by:

$-20 - 25 + F = 0$

Where,

F: force with which Gunther pulls the rope.

Clearing F we have:

$F = 20 + 25\\F = 45$

The positive sign indicates that Gunther pulls to the right.

Answer:

A force that would result in a balanced force for the game is:

$F = 45 N$

Line SU intersects Line TV at point R. What is the value of x, in degrees?

umka2103 [35]

Answer: X is equal to 30

Step-by-step explanation: I found this by taking 75 + 15 which is 90 then dividing it by 3 so 30. This is correct because since the linear pair is equal to 75 degrees then this also needs to be 75 degrees and 3 x 30 = 90 and 90 - 15 = 75.

Hope this helps.
