Answer:
Step-by-step explanation:
80% = 80/100 which also = 4/5
so the price was reduced by 4/5
20 minus 4/5 is = to 20 minus 16/20
which is 20/20 minus 16/20 = to 4/20
simplified is 4 dollars

[tex]\huge\boxed{\text{(C) } 6x > 4x-3}[/tex]
Step-by-step explanation:
We can convert this word problem into an equation by examining what it says.
6 times a number
Since we don't know the value of that number, we can represent it as [tex]x[/tex]. 6 times [tex]x[/tex] will be [tex]6x[/tex]
Greater than has this symbol: [tex]>[/tex]
3 less than 4 times a number. We can break this down. 4 times a number is [tex]4x[/tex]. 3 less than that will be [tex]4x-3[/tex].
Combining that all, we get [tex]6x > 4x-3[/tex]
Hope this helped!

Para executar um serviço, o trabalhador apoiou na laje de sua casa a escada de 4,3 m de comprimento como mostra o esquema abaixo: A base da escada, apoiada sobre um piso horizontal está afastada 1,8 m da parede. Qual é a altura aproximada da construção?
Responda:
3,91 m
Explicação passo a passo:
Dado o seguinte:
Comprimento da escada = 4,3 m
Distância da base da parede = 1,8m
Altura da parede =?
O problema pode ser resolvido usando Pitágoras:
hipoteno = sqrt (oposto² + adjacente ²)
Hipoteno = comprimento da escada = 4,3
4,3 = sqrt (1,8² + altura²)
Quadrar ambos os lados
4,3² = 1,8² + altura²
4,3² - 1,8² = altura²
18,49 - 3,24 = altura²
15. 25 = altura²
Tire a raiz quadrada de ambos os lados
Sqrt (15,25) = altura
Altura = 3,905
Altura = 3,91 m

6 men and 10 women can finish making pots in 8 days, while the 4 men and 6 women can finish it in 12 days. Find the time taken by the one man alone from that of one woman alone to finish the work.
Answer:
48 days
Step-by-step explanation:
Let us assume the following things
Work done by 1 man in 1 day is [tex]\frac{1}{x}[/tex]
Work done by 1 woman in 1 day is [tex]\frac{1}{y}[/tex]
It is mentioned that
six men + ten women finished in 8 days
So,
[tex]\frac{6}{x} + \frac{10}{y} = \frac{1}{8}[/tex] .............. (1)
And,
four men + six women finished in 12 days
[tex]\frac{4}{x} + \frac{6}{y} = \frac{1}{12}[/tex] ...............(2)
Now solve these two equations
And we assume [tex]\frac{1}{x}[/tex] be u and [tex]\frac{1}{y}[/tex] be v
So
Now the equation is
[tex]6u\ + 10v\ = \frac{1}{8} \\\\\4u\ + 6v\ = \frac{1}{12}[/tex]
So,
u = 1 ÷ 48 , v = 0
Therefore x = 48
So the time taken for finish the work is 48 days

If 58 out of 100 students in a school are boys. Write decimal expression for the part of the school that consists of boys.
Answer:

The measure of an angle is 12° more than twice the measure of its complement. Write and solve and algebraic equation to find the measure of each angle. I need help!
Answer:
∠64° and ∠26°
Step-by-step explanation:
Complementary angles add up to 90° total (two angles).
Lets give variable values to each angle:
x= 12 more than twice the measure of the complement
y= complement
Write an equation equaling to a total of 90:
[tex]x+y=90[/tex]
Write an algebraic expression for the value of x:
[tex]12+2y[/tex]
Insert the value for x into the equation:
[tex]12+2y+y=90[/tex]
Simplify and solve for y:
[tex]12+3y=90\\\\12-12+3y=90-12\\\\3y=78\\\\\frac{3y}{3}=\frac{78}{3}\\\\ y=26[/tex]
The value of y is 26. Insert this value into the original equation and solve for x:
[tex]x+26=90\\\\x+26-26=90-26\\\\x=64[/tex]
The value of x is 64. So, the complemenatry angles are 64° and 26°.
:Done
From the given measure whose angle is 12° more than twice the measure of its complement.
The measure of the two angles is 64° and 26° respectively.
Complementary angles are angles whose sum is equal to 90°. It is usually composed of two angles complementing themselves. Hence, the term complementary angles.
Mathematically;
Let the first angle be p and the second angle be q∴
p + q = 90° ( complemntary angles)
If one of the angles is 12 more than twice its complement;
i.e.
Let p = 12
SO, the algebraic equation for the value of p is:
12 + 2q = 90
Replacing the value of q to solve the equation, we have:
12 + 2q + q = 90
12 + 3q = 90
3q = 90 - 12
3q = 78
q = 78/3
q = 26°
From p + q = 90° ( complemntary angles)
Replacing the value of q = 26°, we have:
p + 26° = 90°
p = 90° - 26°
p = 64°
In conclusion, the measure of each angle is 64° and 26°.

Answer:
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one.

Midori cleans the hamster cage every 7 days, brushes the dog every 9 days, and cleans the frog aquarium
every 6 days. If Midori does all three today, how many days will pass before Midori takes care of all three of
these pets on the same day again?
Answer:
126
Step-by-step explanation:
The least common multiple of 7, 9, and 6 is the product of the unique factors.
7 = prime
9 = 3^2
6 = 3·2
The LCM is 7·3^2·2 = 126
Midori will take care of all three pets again after 126 days.
Your family is going to the movies. Your mom bought 5 tickets and spent $51. The tickets for the adults and children sold for $12 and $9, respectively. How many of each kind of ticket were sold? Write one of the equations needed for the system. (must use variables a and c. do not use the space bar when typing answer)
Answer:
adults 2
children 3
Step-by-step explanation:
x + y = 5
12x + 9y = 51
x = 5 - y
12(5 - y) + 9y = 51
60 - 12y + 9y = 51
-3y + 60 = 51
-3y = 51 - 60
-3y = -9
y = -9/-3
y = 3
x = 5 - y
x = 5 - 3
x = 2
