Answer:

P=25

Step-by-step explanation:

Hi! Let's start with with the average...

First we multiply 35 by the amount of numbers we have

We have 5 including the unidentified

so...

35x5=175

Now since we have 175 we have to add all the other numbers together

30+36+40+44=150

Next we subtract

175-150= 25

P= 25

To check our answer add all of them together

40+30+40+44+25=175

We were right!

Hope this helps! :)

The train station clock runs too fast and gains 8 minutes every 10 days. How many minutes and seconds will it have gained at the
Dvinal [7]

Answer:

At the end of 7 days, it will have gained 5 minutes and 36 seconds.

Step-by-step explanation:

This question can be solved using a rule of three.

It gains 8 minutes every 10 days. How much does it gains every 7 days?

7 days - x minutes

10 days - 8 minutes

10x = 7*8

10x = 56

x = \frac{56}{10}

x = 5.6

Each 7 days, it gains 5.6 minutes. That is, it gains 5 full minutes, plus 0.6 = 60% of a minute, in seconds.

A minute has 60 seconds. 0.6*60 = 36

So

At the end of 7 days, it will have gained 5 minutes and 36 seconds.

5y-3y+1=7<br><br> solve for y
Juli2301 [7.4K]

Answer:

y=3

Step-by-step explanation:

Let's solve your equation step-by-step.

5y−3y+1=7

Step 1: Simplify both sides of the equation.

5y−3y+1=7

5y+−3y+1=7

(5y+−3y)+(1)=7(Combine Like Terms)

2y+1=7

2y+1=7

Step 2: Subtract 1 from both sides.

2y+1−1=7−1

2y=6

Step 3: Divide both sides by 2.

2y /2 = 6 /2

y=3
