Answer:

-15

Step-by-step explanation:

We have the expression 3(2p - 5) - 6p and are asked to simplify.

Let's distribute, which is to multiply a number that is outside of a parenthesis bracket by the numbers inside the parenthesis.

3(2p - 5) - 6p

(3(2p) - 3(5)) - 6p

6p - 15 - 6p

Since you can only do changes to like terms and 15 and 6p are two different terms, we do 6p - 6p.

6p - 6p

Leaving us with -15.

Omar has 2-5/8 cups of dough to make dumplings. If he uses 3/16 cup of dough for each dumpling, how many whole dumplings can Oma

Arte-miy333 [17]

Answer:

The number of whole dumpling does Omar make is 14 .

Step-by-step explanation:

Given as :

The number of cups does Omar has to make dumplings = x = 2 $\dfrac{5}{8}$

i.e x = $\dfrac{16 + 5}{8}$

or, x = $\dfrac{21}{8}$

Again

The number of cups uses for each dumpling = y = $\dfrac{3}{16}$

i.e y = $\dfrac{3}{16}$

Let The number of whole dumpling does Omar make = z

So, number of whole dumpling does Omar make = $\dfrac{\textrm number of cups does Omar has to make dumplings}{number of cups uses for each dumpling }$

Or, z = $\dfrac{x}{y}$

Or, z = $\frac{\frac{21}{8}}{\frac{3}{16}}$

Or, z = $\frac{21\times 16}{8\times 3}$

∴ z = 7 × 2

i.e z = 14

So, The number of whole dumpling does Omar make = z = 14

Hence, The number of whole dumpling does Omar make is 14 . Answer

107,600 115,220 104,910 median, mode, mean

san4es73 [151]

Answer:

1. Mean = 342.7 (Rounding to the nearest tenth)

2. Median = 167.5

3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once.

Step-by-step explanation:

Given this set of numbers: 107, 600, 115, 220, 104, 910, find out these measures of central tendency:

1. Mean = 107 + 600 + 115 + 220 + 104 + 910/6 = 342.7 (Rounding to the nearest tenth)

2. Median. In this case, we calculate it as the average between the third and the fourth element, this way:

115 + 220 =335

335/2 = 167.5

3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once. All the data values occur only once.
