1 answer:
Wittaler [7]3 years ago

Answer:

-4 5/12

Step-by-step explanation:

-23/3 + (-11/2) + 35/4

<em>Find a common denominator (12).</em>

-92/12 + (-66/12) + 105/12

<em>Reform the equation to have this as a single fraction.</em>

(-92 + (-66) + 105)/12

<em>Subtract 66 from -92 to get -158.</em>

(-158 + 105)/12

<em>Add 105 to -158 to get -53.</em>

-53/12

<em>Convert into a mixed number by dividing by 12.</em>

-4 5/12 (Choice A) is your answer.

TEA [102]
76 out of 80 people for David.

Therefore, 76/80 people for David.

Further simplifying, every 19 out of 20 people voted for David.

What's 19 out of 20? 

20 x 5 = 100
19 x 5 = 95

95% of the club members voted for David.

(9x−2.25)=(1.6+9x)<br><br> help
mel-nik [20]
Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.

Can some help me with this question
Luden [163]

To find the equation of this line in slope-intercept form (y = mx + b, where m is its slope and b is its y-intercept), we naturally need the slope and the y-intercept. We can see that the line intersects the y-axis at the point (0, 4) so our y-intercept is 4, and the line rises 4 along the y-axis for every 2 it runs along the x-axis, so its slope is 4/2 = 2. With this in mind, we can write the line's equation as

y = 2x + 4

Describs how to identify the coordinate of an improper fraction on a number line.
Ainat [17]

Answer:

Step-by-step explanation:In order to graph the improper fraction you have to change it to a mixed number

say we have 4/3 ,as a mixed number it would be 1 1/3 so we would graph

the 1 1/3 at 1 and break the space in between 1 and 2 into 3 and mark the first 3rd tally
