There are only blue cubes,yellow cubes and green cubes in a bag.There are twice as many blue cubes as yellow cubes and four time
USPshnik [31]
Hey there :)

Let us translate the sentence into mathematics step by step:
There are twice as many as blue cubes as yellow cubes
2 x yellow = 2 cubes = blue         
1 cube = yellow 

There are four times as many as green cubes as blue cubes
4 x 2 ( blue cubes ) = 8 cubes = green

Total cubes = yellow + blue + green
                    =      1      +   2    +    8
                    = 11 

Hannah takes random cube
Probability that Hannah takes yellow cube:
P = number of Yellow cubes ÷ Total number of cubes
P = \frac{1}{11}

-1.3n =7.8 need help​
xxMikexx [17]

Hey there!

-1.3n = 7.8

First, you have to DIVIDE both sides by -1.3

-1.3n / -1.3 = 7.8 / -1.3

Cancel out: -1.3 / -1.3 because it gives you the value of 1

Keep: 7.8 / -1.3 because it gives us the value of n

7.8 ÷ -1.3 = -6

Thus, n = -6 ✅

Good luck on your assignment and enjoy your day!
