Several designers created scale drawings of a new technology lab. Each designer used a different scale. The actual length of a rectangular platform used for assembling robots is 6 feet. In Jamal's
drawing, the platform measures 1.2 inches in length and 1 inch in width. What is the actual width of
the platform? Write a proportion to justify your answer.
Let w be the actual width of the platform, in feet. Write a proportion for the actual width.

step-by-step explanation:

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

• before the lesson, students attempt the assessment task individually. you then review students’

solutions and formulate questions that will them improve their work.

• during the lesson, students work collaboratively in pairs or threes, plotting graphs, completing

tables of values and deducing equations. then, based on the number of common solutions,

students link these representations.

• in a follow-up lesson, students receive your comments on the assessment task and use these to

attempt the similar task, approaching it with insights gained from the lesson.
