I need to collect 30 stickers. Each bag of crisps contains 3 stickers. How many bags will I need to buy?
soldier1979 [14.2K]
Hey there :)

Let p represent the number of bags to be bought

We need to collect 30 stickers and each bag has 3 stickers

                    3p                                =                        30
                      ↑                                                           ↑
Number of stickers in a bad       Number of stickers to be collected

\frac{3p}{3} = \frac{30}{3}
p = 10

We need to buy 10 bags of crisps to have 30 stickers

Find the y intercept of -2,5 and 3,25
AlexFokin [52]

Answer:

Y-intercept = 13

Step-by-step explanation:

Since, given points are:  

(-2,5) and (3,25)

Now, by slope intercept form:

y= mx + b

Here, m= slope and b= y-intercept

In order to find y-intercept, we must find slope firstly:  

Since,

Slope= m= y2-y1 / x2-x1  

m= 25 - 5 / 3 - (-2)

m= 20 / 5  

m= 4  

Put ‘m’ in slope intercept form:

y= 4x + b  

Substitute either point into above equation:

25= 4(3) +b

25= 12 + b  

25 - 12 = b

or b= 25 - 12

b= 13

Hence, y-intercept is 13.

Dorothy types 120 words per minute. How many words does Dorothy type in 1.75 minutes?
nirvana33 [79]
As you are looking for 1.75 minutes (or 105 seconds), the best thing to do is to find how many words she can type in 0.25 minutes (this is a quarter, and you can divide 1.75 by this). To find a quarter, you have to divide by 4, 120/4= 30. Therefore, every 15 seconds, Dorothy can type 30 words. As you've got 105 seconds, divide this by 15, and this gives you 7. Then multiply 30 by 7, and this gives you 210.
Dorothy can type 210 words in 1.75 minutes
Hope this helps :)
