$\huge\text{Hey there!}$

$\large\text{When you hear/see the word of in mathematics, it usually means }\\\large\text{\bf multiplication. }$

$\large\text{So, when you think of think of the word \underline{of} think of its asking you to}\\\large\text{\bf multiply }$

$\large\text{Now that we got that run down out of the way lets answer your given}\\\large\text{question}$

$\large\textsf{0.25\% of 2,000}$

$\large\textsf{= 0.25\%} \times \large\textsf{2,000}$

$\large\textsf{0.25\%} = \mathsf{\bf \dfrac{25}{100}}$

$\mathsf{= \dfrac{25}{100} \times 2,000}$

$\mathsf{\dfrac{25}{100}= \bf 0.0025}$

$\large\textsf{= 0.0025} \times \large\textsf{2,000}$

$\large\text{= \bf 5}$

$\boxed{\boxed{\huge\text{Therefore, your ANSWER is: \textsf 5}}}\huge\checkmark$

A ladder leans against a window in a two-story building. the window is 16 feet off the ground. the base of the ladder is 12 feet

Kitty [74]

A^2 + b^2 = c^2
16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2
sqrt 400 = c
20 = c <== the ladder is 20 ft long

How do I solve this system of equations by substitution? <br> y - 3x = 2, y=(x + 1)^2 - 5

Arada [10]

Hello,

y-3x=2==>x=(y-2)/3
==>(x+1)²=((y-2)/3+1)²=(y+1)²/9

y=(x+1)²-5
==>y=(y²+2y1)/9 -5
==>y²-7y-44=0 ; Δ=7²+4*44=225=15²
==>y=(7+15)/2 or y=(7-15)/2

==>y =11 and x=(11-2)/3=3
or y=-4 and x=(-4-2)/3=-2

sol={(3,11);(-2,-4)}
