Could someone please help answer this, please no spam, will give brainliest, thank you!

Answer:

$x>-5$

Step-by-step explanation:

$\frac{-1}{5} x+1$

Subtract 1 from both sides

$\frac{-1}{5} x+1-1$

Simplify

$\frac{-1}{5} x$

Multiply both sides by -1, which reverses the inequality also

$\frac{-1}{5} x(-1)>1(-1)$

Simplify

$\frac{1}{5} x>-1$

Multiply both sides by 5

$5*\frac{1}{5} x>5(-1)$

Simplify

$x>-5$

this is kinda confusing but it says “if 1 cm represents 2 meters, how long would each measurement be on an actual basketball cou

frosja888 [35]

Answer:

28 m
15 m
24.8 m
1.0 m

Step-by-step explanation:

The given statement is the scale factor:

$\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}$

This can be rearranged to the formula ...

$\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}$

Filling in the given scale distances, you find the actual distances to be ...

$\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\$
