So do 21/7 to give you how much they do in a day. The answer is three so they do 3 aceres in a day.
Answer:
$63.36
Step-by-step explanation:
The home audio system costs $264 wholesale.
The system's price had been increased by 60 percent at the electronics retailer.
Consequently, the increased cost is 60/100x264=$158.40.
The audio system's total cost is now $422.40 (264 + 158.40).
Given that Lori received a commission of = 15% on $422.40, her commission is now (15/100) x 422.40
= $63.36
Answer:
she started with 50 marbles
Step-by-step explanation:
The total is 100 than you just subtract 20 and 30 becasue that is what is added later on. After you subtract 20 and 30 from 100 you will get 50. Therefore Sara had started out with 50 marbles.
Hope that helps :)
Recuerda que
• |<em>x</em>| = <em>x</em> si <em>x</em> ≥ 0
• |<em>x</em>| = -<em>x</em> si <em>x</em> < 0
Necesitas considerar dos casos:
• si <em>x</em> - 3 ≥ 0,
|<em>x</em> - 3| < 1 ⇒ <em>x</em> - 3 < 1 ⇒ <em>x</em> < 4
• si <em>x</em> - 3 < 0,
|<em>x</em> - 3| < 1 ⇒ -(<em>x</em> - 3) = 3 - <em>x</em> < 1 ⇒ -<em>x</em> < -2 ⇒ <em>x</em> > 2
Entonces la solución consta de todos los números reales <em>x</em> tales que <em>x</em> > 2 y <em>x</em> < 4, o simplemente 2 < <em>x</em> < 4.
El método para resolver las otras desigualdades es el mismo.
|4<em>x</em> + 1| > 0 ⇒ 4<em>x</em> + 1 > 0 o -(4<em>x</em> + 1) > 0
… ⇒ 4<em>x</em> + 1 > 0 o -4<em>x</em> - 1 > 0
… ⇒ 4<em>x</em> > -1 o -4<em>x</em> > 1
… ⇒ <em>x</em> > -1/4 o <em>x</em> < -1/4
⇒ <em>x</em> ≠ -1/4
|<em>x</em> - 1| < 5 ⇒ <em>x</em> - 1 < 5 o -(<em>x</em> - 1) < 5
… ⇒ <em>x</em> - 1 < 5 o -<em>x</em> + 1 < 5
… ⇒ <em>x</em> < 6 o -<em>x</em> < 4
… ⇒ <em>x</em> < 6 o <em>x</em> > -4
⇒ -4 < <em>x</em> < 6
2 positive unit tiles are needed to complete the factorization.
Given
The partial factorization of x^2 – 3x – 10 is modeled with algebra tiles.
<h3>Partial factorization;</h3>
Partial fractions are the fractions used for the decomposition of a rational expression.
When an algebraic expression is split into a sum of two or more rational expressions, then each part is called a partial fraction.
In the second line, we can see that first term 1 is labeled + x squared, second is labeled +<u> </u><u>2x</u><u> (two positive </u><u>tiles </u><u>above),</u> then the 5 tiles below + x squared are labeled negative x, and the 10 tiles below the + x tiles are labeled negative.
The negative values are represented as tiles labeled below (negative tiles) while positive values are tiles labeled above (positive tiles).
Therefore,
The factorization is;
Hence, 2 positive unit tiles are needed to complete the factorization.
