Answer:
2<x<3
Step-by-step explanation:
the first one
Answer:
x > -2
Step-by-step explanation:
3(1 – x) < 9
Divide each side by 3
3/3(1 – x) < 9/3
1-x < 3
Subtract 1 from each side
1-x-1 < 3-1
-x < 2
Multiply each side by 1, remembering to flip the inequality
-x*-1 > 2*-1
x > -2
Open circle at -2, line going to the right
Answer:
<h2>
64 cm²</h2>
Step-by-step explanation:
given:
the scale from a square park to a drawing of the park is 5 m to 1 cm
the actual park has an area of 1,600 m²
find:
what is the area of the drawing of the park
solution:
drawing scale is 5m : 1cm
<u>1,600 m² </u> = <u> 5² m² </u>
x 1² cm²
cross multiply:
5² m² x = 1600 m² (1 cm²)
x =<u> 1600 m² </u>
5² m²
x = 64 cm²
therefore, the area of a square park in the drawing is 64 cm²
