B) Models the equation, because:
Because y = money earned and x = amount of books she sells
When she sells a copy of each book this can be modeled by "2x"
When ever she sell's books, she get's a $5 tip (not affected by x),
Please vote mine the brainliest answer if I helped!
It's $6.48 divided by 4. So the answer is $1.62
Represent the unknowns.
<span>Let x = length </span>
<span>since the width is 3/4 of the length, </span>
<span>Let (3/4)x = width </span>
<span>Recall that the area of rectangle is just width multiplied by the length, </span>
<span>A = w * l </span>
<span>Substituting, </span>
<span>432 = (3/4)x * x </span>
<span>432 = (3/4)x^2 </span>
<span>432 * 4/3 = x^2 </span>
<span>576 = x^2 </span>
<span>Get the square root of both sides, </span>
<span>x = 24 feet (length) </span>
Answer:
The answer is x=2
Step-by-step explanation:
81∧x = 3∧x + 6
3∧4x = 3∧x + 6
4x = x + 6
4x - x = 6
3x = 6
x = 2
