Annalisa, Keiko, and Stefan want to compare their heights. Annalisa is 64 inches tall. Stefan tells her, "I'm about 7.5 centimeters taller than you." Keiko knows she is 1.5 inches shorter than Stefan. Give the heights of all three people in both inches and centimeters to the nearest half unit. Annalisa is 64 inches or about cm tall. Stefan is about inches or about cm tall. Keiko is about inches or about cm tall.

As 1 inch = 2.54 cm.

As Annalisa is 64 inches tall,

so the height of Annalisa in centimeter = 64 x 2.54 cm = 162.5 cm (approximately).

Stefen is about 7.5 centimeters taller than Annalisa,

So, height of Stefen in centimeter= 162.5+7.5=170 cm.

and the height of Stefen in inches = 170/ 2.54 cm= 67 inches (approximately).

Keiko is about 1.5 inches shorter than Stefen,

So, the height of Keiko in inches= 67-1.5=65.5 inches.

and the height of Keiko in centimeter = 71.5 x 2.54 cm= 166.5 cm (approximately).

Hence, Annalisa is 64 inches or about 162.5 cm tall.

Stefan is about 67 inches or about 170 cm tall.

Keiko is about 65.5 inches or about 166.5 cm tall.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
