Kisachek [45]

Answer: 2/3

Explanation: Assume that the number of smarties he picked is c.

Now, we are given that:

1- He picked 3 times as many cola bottles as smarties. This means that:

Number of cola bottles he picked = 3s

2- He picked twice as many smarties as marshmallows. This means that:

number of marshmallows he picked = 0.5s

Now to get the proportion o f cola bottles, we will divide the number of cola bottles by the total number of sweets as follows:

proportion of cola bottles =  

Hope this helps :)

36/49 = 5/n find n. will mark for whoever answers
Crazy boy [7]

Answer:

  n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

  1. eliminate fractions by multiplying by the LCM of the denominators
  2. divide by the coefficient of the variable.

Doing that, we have ...

  (49n)(36/49) = (49n)(5/n)

  36n = 49·5 = 245 . . . . . simplify

  n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

  49/36 = n/5

Now, all you need to do is multiply by 5.

  n = 5(49/36) = 245/36

__

Or, you can do both of the original steps at the same time:

  (49n/36)(36/49) = (49n/36)(5/n)

  n = (49·5)/36 = 245/36

-2x + y = -4 <br><br> Need help asap
liraira [26]

Answer:

y = 2x - 4

Step-by-step explanation:

Can I ask which variable you are solving?

PS I will assume you need the formula y=mx+b

-2x + y = - 4

Here you would translate the m and x variables to the right side making them positive.

y = 2x - 4

Now the formula is in proper form
