Sam's height is 15 centimeters less than 2 times Martha's height. If Sam is 185 centimeters tall, and Martha's height is x, the relationship between the heights can be represented by the equation 2x − 15 = 185. What is Martha's height? A)90 b)95 c)100 d)105.
En resumen
Sólo sería despejar a "x" 2x - 15 = 185 2x = 185 + 15 x = 200 / 2 x = 100 cm. Altura de martha. Opción c) - - >R / .

2x - 15 = 185
2x = 185 + 15
x = 200 / 2
x = 100 cm.

Elena tenia 50 y martha 25 elena perdio 10 y martha 5 entonces quedaria elena con 40 y martha 20.
A = 2 b = 4 c = - 3 d = - 2 So : 3ab - 6cd (3(2)(4)) - (6( - 3)( - 2)) (3(8)) - (6(6)) 24 - 36 - 12 I hope it worked.
5 cm = 40 miles 5 cm x 3 = 15 cm = 120 miles (10 miles remain) 5 cm / 2 = 2. 5 cm. 2. 5 cm = 20 miles 2. 5 cm / 2 = 1. 25 cm. 1. 25 cm = 10 miles 15 cm (120 miles) + 1. 25 cm (10 miles) = 16. 25 cm (130 miles).
