Rhea sold 6 boxes of blueberry muffins and 8 boxes of corn muffins at the bake sale. Each box contained 18 muffins. The muffins
Elenna [48]
6 boxes of blueberry muffins and 8 boxes of corn muffins

Since we know that each box has 18 muffins, we can multiply both 6 and 8 to determine the amount of muffins present

6 • 18 = 108 blueberry muffins
8 • 18 = 144 corn muffins

To determine the price, you multiply each type of muffin by 0.50 as each muffin is worth $0.50

108 • 0.50 = 54
144 • 0.50 = 72

You add these two together to get the price

54 + 72 = $126

If you explain what the estimate is, if I didn’t answer that along the way, I can help answer it for you.

What is the slope of the line that contains the point (13,-2) and (3,-2)
ra1l [238]

The slope of the line that contains the point (13,-2) and (3,-2) is 0

<em><u>Solution:</u></em>

Given that we have to find the slope of the line

The line contains the point (13,-2) and (3,-2)

<em><u>The slope of line is given as:</u></em>

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

Where, "m" is the slope of line

Here given points are (13,-2) and (3,-2)

(x_1, y_1) = (13, -2)\\\\(x_2, y_2) = (3, -2)

<em><u>Substituting the values in formula, we get,</u></em>

m = \frac{-2-(-2)}{3-13}\\\\m = \frac{-2+2}{3-13}\\\\m = 0

Thus the slope of line is 0

Divide 260 in the ratio 1:3
den301095 [7]
The divided will 65 and 195.

1:3 =260
1x+3x =260
Add 1x and 3x
4x=260
Divide the four on both sides
4x/4=260/4
x=65
Now find the one for 3 by multiplying
1x=65
3x=195
