All angles would have a sum of 180 degrees, so 180-140 is 40. And if you divide 40 by 2, the two side angles will be 20 degrees.

A cookie recipe calls for 1 2/3 of sugar if you plan on changing the recipe to make it 2 1/2 times as much how many cups of suga

Dimas [21]

Answer:

$4\frac{1}{6}\ cups$

Step-by-step explanation:

we know that

The recipe calls for 1 2/3 of sugar

To make 2 1/2 times the recipe

Multiply 2 1/2 by 1 2/3

Convert mixed numbers to an improper fraction

$1\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}\ cups$

$2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}$

$\frac{5}{2}(\frac{5}{3})=\frac{25}{6}\ cups$

Convert to mixed number

$\frac{25}{6}=\frac{24}{6}+\frac{1}{6}=4\frac{1}{6}\ cups$

I need help please!!!!

zaharov [31]

Answer:

Step-by-step explanation:

The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)

_____

<em>Additional comment</em>

The point-slope form of the equation for a line is ...

y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

The equation might be easier to see if the point chosen were one at a grid intersection, such as (-4, -4) or (6, 8).
