answer as a mixed number if possible. A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl8a week, how many gra
GrogVix [38]

<em>7 grams of sugar</em>

<h2>Explanation:</h2>

________________________________________

I'll assume your answer is as follows:

<em>A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl a week, how many grams of sugar would he have eaten?</em>

________________________________________

If so, then we know that:

  • A bowl of cereal had 3 3/6 grams of sugar in it.
  • Victor ate 2 bowl a week

In other words, the total of sugar he ate can be calculated as:

3\frac{3}{6}\times2 \\ \\ Converting \ mixed \ fraction \ into \ improper \ fraction: \\ \\ =(3+\frac{3}{6})\times2 \\ \\ =(\frac{3(6)+3}{6})\times 2 \\ \\ =(\frac{21}{6})\times 2 \\ \\ =(\frac{7}{2})\times 2 \\ \\ =7

So <em>he'd have eaten 7 grams of sugar</em>

Justin has $7.50 more than Eva, and Emma has $12 less than Justin. Together , they have a total of 63.00. How much money does ea
Setler [38]
Since no value is given to Eva, we'll call her x. Justin, then, is 7.50+x. That leaves Emma, who would be Justin (7.50+x) -12. If we add them all together we get 63. So our equation is

x + (7.50+x) + (7.50+x)-12 = 63

Combine like terms

x+x+x + 7.50+7.50-12 = 63
3x + 3 = 63
3x = 60
x = 20

Since we said Eva is x then Eva has 20 dollars.

Justin is 7.50 + x so 7.50+20=
$27.50

Emma is Justin - 12 so 27.50-12= $15.50

Let's check our answer...

15.50+27.50+20 = 63
63=63

It checks!

Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) an
Tcecarenko [31]
The y-coordinate of the midpoint of a line segment is the average of the y-coordinates of the endpoints of the line segment.

This is: call y1 the y-coordinate of one endpoint and y2 the y-coordinate of the other endpoint of the line segment, then the midpoint is [y1 + y2] / 2.

The method, then, is to add the two y-coordinates and divide by 2.

For the vertical line segment with endpoints  (0,0) and (0,15) theprocedure is [0 + 15] / 2 = 15/2 = 7.5, and the result is 7.5

koban [17]

Answer:

<h2>The slope m = 3</h2>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (2, 5) and (-1, -4). Substitute:

m=\dfrac{-4-5}{-1-2}=\dfrac{-9}{-3}=3
