Answer:

The segment should be 36 centimeters long

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ The original scale is 1 cm : 8 m

∵ In the original drawing, the length of a segment is 9 centimeters

→ By using the ratio method

→  cm   :  m

→  1      :  8

→  9     :  x

→ By using the cross multiplication

∵ 1 × x = 9 × 8

∴ x = 72 m

∴ The actual length of the segment is 72 m

∵ The new scale is 1 cm : 2 m

∵ The actual length of the segment is 72 m

→ By using the ratio method

→  cm   :  m

→  1      :  2

→  y      :  72

→ By using the cross multiplication

∵ y × 2 = 1 × 72

∴ 2y = 72

→ Divide both sides by 2 to find y

∴ y = 36

∴ The drawing length of the segment is 36 cm in the new scale

∴ The segment should be 36 centimeters long

What is 35 = -2x - 15 ?
gtnhenbr [62]

Answer:

x=-25

Step-by-step explanation:

35=-2x-15

add 15 to both sides, cancels the 15 from the right

50=-2x

divide both sides by -2, isolates the x

-25=x
