A rectangle has a length of 28 feet less than 6 times its width. If the area of the rectangle is 48 square feet, find the length of the rectangle.
brainliest and thanks <3
help asap
Answer:
length = 8
Step-by-step explanation:
l x w = 48
let l = 6w - 48
x(6w - 28) = 48
6w² - 28w - 48 = 0
(6w + 8) (w - 6) = 0
w = 6
l = 6(6) - 28 = 36 - 28 = 8

-31-4=-5-25x-5
Answer:
x = 1
Step-by-step explanation:
- 31 - 4 = - 5 - 25x - 5
− 3 5 = − 5 − 2 5 − 5
− 3 5 = − 2 5 − 1 0
− 3 5 + 1 0 = − 2 5 − 1 0 + 1 0
− 2 5 = − 2 5
− 2 5 = − 2 5
-25/-25 = - 25x/- 25
x = 1
Answer:
X=1
Step-by-step explanation:
1)Subtract the numbers
-31-4=-5-25x-5
-35=-5-25x-5
2)Subtract the numbers
-35=-5-25x-5
-35=-10-25x
3)Rearrange terms
-35=-10-25x
-35=-10-25x
4)Add 10 to both sides of the equation
−35=−25−10
−35+10=−25−10+10
5)Simplify
−25=−25x
X=1

Veronica is saving $100 each month. Verónica wants to
accumulate $1100 in savings. About how many years will
it take Veronica to save that much?
A. A little under 1 1/2 years
B. Exactly 1 1/2 years
C. A little under 1 year
D. Exactly 1 year
Answer:
C. A little under 1 year
Step-by-step explanation:
Since Veronica is saving $100 each month.
So,
in the first month she will save = $100
in the second month she will save = $200
in the third month she will save = $300
Following the same pattern, she will accumulate $1100 in 11 month.
11 moths is 1 month less than a year.
So, Veronica will take A little under 1 year to accumulate $1100.

En una heladería, la nave de envasado está a 12 *C y en el interior a 15*C bajo cero cuál es la diferencia de temperatura?
Answer:
La diferencia de temperatura es de 27 ºC.
Step-by-step explanation:
Los procesos de transferencia de calor se deben a la presencia de gradientes térmicos, es decir, diferencias de temperatura que implican transferencia de energía desde puntos a mayor temperatura a puntos a menor temperatura. Entonces, la diferencia de temperatura ([tex]\Delta T[/tex]), medida en grados Celsius, queda descrita por la siguiente fórmula:
[tex]\Delta T = T_{o}-T_{i}[/tex] (1)
Donde:
[tex]T_{o}[/tex] - Temperatura exterior, medida en grados Celsius.
[tex]T_{i}[/tex] - Temperatura al interior de la nave de envasado, medida en grados Celsius.
Si tenemos que [tex]T_{o} = 12\,^{\circ}C[/tex] y [tex]T_{i} = -15\,^{\circ}C[/tex], entonces la diferencia de temperatura es:
[tex]\Delta T = 12\,^{\circ}C-(-15\,^{\circ}C)[/tex]
[tex]\Delta T = 27\,^{\circ}C[/tex]
La diferencia de temperatura es de 27 ºC.

24 men working at 8 hours perday can do a piece of work in 15 day. in how many days can 20 men working at 9 hours day can complete the same work?
Answer:
16 days
Step-by-step explanation:
24 men works 8 hours a day to complete a work in 15 days. While 20 men works at 9 hours per day to complete the same work in x days. We can find the number of days it took the 20 men by using the expression below:
24 men * 8 hours/day * 15 days = 20 men * 9 hours/day * x days
[tex]x (days)=\frac{24\ men * 8\ hours/day * 15\ days }{20\ men * 9\ hours/day} \\\\Simplifying\ gives:\\\\x(days)=16\\\\x=16\ days[/tex]
Therefore it took 20 men working 9 hours/day, 16 days to complete the same work

Answer:
The correct option is [tex]\frac{4}{15}[/tex].
step-by-step-explantion;
It is Given: Three teaches equally shared [tex]\frac{4}{5}[/tex] of a flat of paper that was donated to the school.
Solution:
3 teachers equally shared [tex]\frac{4}{5}[/tex] of paper.
The fraction of paper each teacher receive = [tex]\frac{4}{5} \div 3[/tex]
The fraction of paper each teacher receive = [tex]\frac{4}{5} \times \frac{1}{3}[/tex]
The fraction of paper each teacher receive = [tex]\frac{4}{15}[/tex]
Hence, the correct option is [tex]\frac{4}{15}[/tex].
