Pierce works at a tutoring center on the weekends. at the center, they have a large calculator to use for demonstration purposes that is a scale model of calculators available for the students to use. each key on the student calculators is 14 millimeters wide, and each key on the demonstration calculator is 2.8 centimeters wide. if the student calculators are 252 millimeters tall, how tall is the demonstration calculator?

504 millimeters (or 50.4 cm)

Step-by-step explanation:

Thus, the demonstration calculator's dimensions are twice that of students' (in cm)

Also given, student calculator height as 252 millimeters (25.2 cm)

Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
