Mathematics

barxatty [35]3 years ago
5 0

Step-by-step explanation:

Let us add x to 2\frac{1}{8} to make 4.

\therefore \: x + 2 \frac{1}{8}  = 4 \\  \\  \therefore \: x + \frac{2 \times 8 + 1}{8}  = 4 \\  \\  \therefore \: x + \frac{16 + 1}{8}  = 4 \\  \\ \therefore \: x + \frac{17}{8}  = 4 \\  \\ \therefore \: x = 4 - \frac{17}{8} \\  \\ \therefore \: x = \frac{4 \times 8 - 17}{8} \\  \\ \therefore \: x = \frac{32- 17}{8} \\  \\ \therefore \: x = \frac{15}{8} \\  \\ \therefore \: x =1 \frac{7}{8} \\  \\  \therefore \:1 \frac{7}{8} \: should \: be \: added \: in \: 2 \frac{1}{8} \: to \: \\  \:  \:  \:  \:  \:  make \:  it \: \: 4.

Complete table below then write an equation that relates to x and y
kvasek [131]
I think y is always 3 less than x. So for the first blank it would be 3 less than -1, that is -4. That makes the second blank -3. The third -8. And the last, -5.
The equation might be x-3=y
I might be wrong, please tell me if this is correct.

how many ways are there to distribute 11 identical candies between 4 children such that each child receives at least 2 candies
GREYUIT [131]

There are 15 / 2 ways to distribute 11 identical candies between 4 children such that each child receives at least 2 candies.

If we give child A four candies and so we were left with 9 candies.

In addition, we will take child A away from consideration to ensure he received exactly four candies, and thus we were left with 9 dots and 2 slashes, separating the 4 remaining distinct children.

So the possible ways are:  (11 + 4 / 2) = (15 / 2).
