Answer:
[tex]w=-9/8[/tex]
Step-by-step explanation:
We are given the equation [tex]-2 \frac{1}{4} = 2w[/tex]. To solve this equation, we can divide both sides by 2 to get that [tex]w = -2\frac{1}{4} \div 2 = -\frac{9}{8}[/tex].
Answer:
w = - [tex]\frac{9}{8}[/tex]
Step-by-step explanation:
Given
- 2 [tex]\frac{1}{4}[/tex] = 2w ( change the mixed number to an improper fraction )
- [tex]\frac{9}{4}[/tex] = 2w ( multiply both sides by 4 to clear the fraction )
- 9 = 8w ( divide both sides by 8 )
- [tex]\frac{9}{8}[/tex] = w
A 4-column table with 5 rows. Column 1 has entries 25 percent, 25 percent, 25 percent, 25 percent, 100 percent. Column 2 has entries 0.25, 0.25, 0.25, 0.25, 1. Column 3 has entries one-fourth, one-fourth, one-fourth, one-fourth, 1. Column 4 has entries 14, 14, 14, 14, 56.
Which expressions can you use to find 75% of 56? Check all that apply.
0.25 × 56
Three-fourths × 56
0.75 × 56
One-fourth × 56
3 × 14
Answer:
Three-fourths × 56
0.75 × 56
3 × 14
Step-by-step explanation:
To obtain 75% of 56 ;
Mathematically ;
75% of 56 = 75/100 * 56 = 42 (valid)
= 0.75 * 56 ( valid)
(75/100) * 56 = (3/4) * 56 = 42 (valid)
(75/100) * 56 = (3/4) * 56 = 3 * (56/4) = 3 * 14 = 42 (valid)
0.25 * 56 = 14 ( invalid)
(1/4) * 56 = 14 (invalid

Is 2 a solution of 4x + 12= 4? Complete the statement. The equation is (true, false) when x = 2, so 2 (is, is not) a solution. WILL MARK BRAINLIEST
Answer:
The answer is false and is not
Explanation:
Given the equation - [tex]4x+12=4[/tex]
Substitute x = 2 in the equation
[tex]4(2)+12=4\\8+12=4\\20=4[/tex]
Thus, the equation is false. When the equation is false, meaning that the coordinate x-term isn't passed by the line. (Rather say that the point is not the part of the graph.)
The equation is false is our first answer.
If the equation is false, that means the given value is not part of the graph, thus making the x-value not the solution.
Answer:
The equation is FALSE when x=2, so 2 IS NOT a solution.
Write two expressions with unlike denominators whose sum is x-3/x+2, I need help it is confusing for me.
Answer:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Step-by-step explanation:
We need to find two expressions with unlike denominators what sum
[tex]\displaystyle S=\frac{x-3}{x+2}[/tex]
Let's suppose one of the expressions is:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
Now we subtract S minus A to find the other expression B:
[tex]\displaystyle B=S-A=\frac{x-3}{x+2}-\frac{x-2}{x+3}[/tex]
Multiply the first fraction by x+3 and the second by x+2;
[tex]\displaystyle B=(x+3)\frac{x-3}{(x+3)(x+2)}-(x+2)\frac{x-2}{(x+3)(x+2)}[/tex]
Operating:
[tex]\displaystyle B=\frac{x^2-9}{(x+3)(x+2)}-\frac{x^2-4}{(x+3)(x+2)}[/tex]
Subtracting both fractions with like denominators:
[tex]\displaystyle B=\frac{x^2-9-(x^2-4)}{(x+3)(x+2)}[/tex]
Simplifying:
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Thus the two expressions are:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
And
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Diego compro un libro y tres cuadernos,pago por ellos 180 solo recuerda que el libre le costó el doble de lo que le costaron los tres cuadernos juntos
Answer: Cada cuaderno cuesta 20, y el libro 120.
Step-by-step explanation:
Vamos a definir:
L = precio de un libro
C = precio de un cuaderno.
Sabemos que Diego compro un libro y tres cuadernos por 180, entonces tenemos:
1*L + 3*C = 180
También sabemos que el libro costo el doble de lo que costaron los 3 cuadernos juntos, entonces:
L = 2*(3*C) = 6*C
Tenemos un sistema de ecuaciones:
1*L + 3*C = 180
L = 6*C
Para resolverlo, podemos reemplazar la segunda ecuación en la primera, para así obtener:
1*(6*C) + 3*C = 180
6*C + 3*C = 180
9*C = 180
C = 180/9 = 20
Cada cuaderno costo 20.
Y el precio del libro se puede obtener con la ecuación:
L = 6*C = 6*20 = 120
El libro costo 120

64 + 144 = 208
Jamie went to dinner. Her meal cost $12.40. She wanted to leave a 15%
tip. How much was her tip?
Answer:
Hi there! The answer is $1.86. Hope this helps! c:
Step-by-step explanation:
First, convert 15% to a decimal.
15% / 100 = 0.15
Then, multiply.
0.15 * 12.40 = $1.86
Since 15% of 12.40 is $1.86, then Jamie left a $1.86 tip.

f(x) = 5x^2 – 20
Answer:
x=-2, 2.
Step-by-step explanation:
5x^2-20=0
factor out the 5
5(x^2-4)=0
5(x+2)(x-2)=0
(x+2)(x-2)=0/5
(x+2)(x-2)=0
x+2=0, x-2=0
x=0-2=-2,
x=0+2=2.
