< means open circles

x-21<3 x≥21

-x+21<3 x<21

18<x<21 and 21≤x24

Josie is making pizza dough. Complete the double number line by filling in the missing values. Then write an equation that model

coldgirl [10]

Answer:

First part:

To complete the top number line use the numbers

$1\dfrac{1}{2}$

and

$2\dfrac{1}{4}$

To complete the bottom number line use the numbers:

3, and

Second part:

The relationship between the total cups of flour, c, and number of batches n, is:

$c=\dfrac{3}{4}n$

Explanation:

Find the complete question if the file attached.

First part.

The number line on top shows the number of cups of flour, c.

Each mark corresponds to 3/4 of cups. Thus the numbers that complete the number line are:

$\dfrac{3}{4}+\dfrac{3}{4}=\dfrac{6}{4}=\dfrac{4}{4}+\dfrac{2}{4}=1+\dfrac{1}{2}=1\dfrac{1}{2}$

$1\dfrac{1}{2}+\dfrac{3}{4}=1+\dfrac{1}{2}+\dfrac{3}{4}=\dfrac{4}{4}+\dfrac{2}{4}+\dfrac{3}{4}=\dfrac{9}{4}=\dfrac{8}{4}+\dfrac{1}{4}=2+\dfrac{1}{4}=2\dfrac{1}4}$

The the two numbers that complete the top number line are:

$1\dfrac{1}{2}$

and

$2\dfrac{1}{4}$

The bottom number line models the number of batches of dough, n.

Each mark corresponds to one unit, i.e. one batch.

Thus, the missing values are:

2 + 1 = 3, and

3 + 1 = 4.

Second part. Find the relationship between the total cups of flour, c, and number of batches n.

The relationship is indicated by the marks that are at equivalent position:

You can notice that you must multiply the number of batches, n, by 3/4 to get the number of cups of flour, c, that correspond to the same position:

For instance:

$1\times \dfrac{3}{4}=\dfrac{3}{4}$

$4\times \dfrac{3}{4}=3$

Therefore,

$c=\dfrac{3}{4}n$

2p/9+5p/18-5/6=2/3+p/12+1/6

Murljashka [212]

$\frac{2p}{9} + \frac{5p}{18} - \frac{5}{6} = \frac{2}{3} + \frac{p}{12} + \frac{1}{6}$
$\frac{4p}{18} + \frac{5p}{18} - \frac{5}{6} = \frac{2}{3} + \frac{p}{12} + \frac{1}{6}$
$\frac{9p}{18} - \frac{5}{6} = \frac{4}{6} + \frac{1}{6} + \frac{p}{12}$
$\frac{p}{2} - \frac{5}{6} = \frac{5}{6} + \frac{p}{12}$
$\frac{p}{2} - \frac{5}{6} + \frac{5}{6} = \frac{5}{6} + \frac{5}{6} + \frac{p}{12}$
$\frac{6p}{12} = 1\frac{2}{3} + \frac{p}{12}$
$\frac{6p}{12} - \frac{p}{12} = 1\frac{2}{3} + \frac{p}{12} - \frac{p}{12}$
$\frac{12}{5} * \frac{5p}{12} = 1\frac{2}{3} * \frac{12}{5}$
$p = 4$

Select the favorable outcomes for rolling a sum less than five

Anvisha [2.4K]

We want the sum of the two rolls to be less that five.
Therefore, we will examine each given set of choices and choose the one where all the points have a sum less than 5.

First set: all the point are 5 added to another number. Therefore, the sum is definitely not less than 5. This choice is rejected.

Second set: We have two points having 6 added to a number. Therefore, this choice is also rejected.

Third set: We have the points (5,5) and (6,6) which have a sum greater than 5. Therefore, this set is also rejected.

Fourth set: We have:
(1,1) with sum = 2
(1,2) with sum = 3
(1,3) with sum = 4
(2,1) with sum = 3
(2,2) with sum = 4
(3,1) with sum = 4
Therefore, all sums are less than 5. This is the correct choice.

Based on the above, the correct option is the last one.
