Answer:
2
Step-by-step explanation:
You would replace the x with -2x so you would end up with -2×-2 and that is 4 then minus 2 is 2.

Approximate √10 to the nearest whole number
Answer:
3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Since square rooting (√) is the opposite function of squaring a number (exponent of 2), to approximate √10 to the nearest whole number, determine the two squares it is in between.
If you square 3, you will get 9 (3 x 3 = 9) and if you square 4, you will get 16 (4 x 4 = 16). Since 10 is in between 9 and 16, √10 will be in between 3 and 4.
The difference between 9 and 10 is only 1, while the difference between 10 and 16 is 6. Therefore, √10 is closest to 3.

1.Tu familia compro un paquete de galletas, al abrirlas se comieron la mitad de ellas, entre tu papá, mamá, hermano mayor, hermana menor y tú, comiendo la misma cantidad de galletas; después llego tu tía y primo y ellos se comieron la mitad de lo que quedaba, donde tu primo se comió 10 galletas más que tu tía; luego llego tu tío y se comió la mitad del resto y finalmente, tú tomas de galletas de lo que queda, sobrando 30 galletas.
1. Cuantas galletas había en el paquete
Cuántas galletas se comió tu
1. mamá
2. papá
3. hermano mayor
4. hermano menor
5. tía
6. primo
7. ¿Cuántas galletas comiste tú?
8. Quién comió más galletas?
Answer:
Para determinar cuantas galletas comió cada integrante de la familia, se debe realizar la siguiente ecuación:
P + M + HMA + HME + YO = 1/2 X
(PR+10) + TIA = 1/4 X
TIO = 1/8 X
Sobran 30 galletas, es decir, 1/8 X
Punto 1)
Si 1/8 X es igual a 30, en el paquete había 240 galletas (30 x 8).
Punto 2)
1- Mamá comió 24 galletas (30 x 4 / 5)
2- Papá comió 24 galletas (30 x 4 / 5)
3- Hermano mayor comió 24 galletas (30 x 4 / 5)
4- Hermano menor comió 24 galletas (30 x 4 / 5)
5- Tía comió 25 galletas ((30 x 2 - 10) / 2)
6- Primo comió 35 galletas ((30 x 2 + 10) / 2)
7- Yo comí 24 galletas (30 x 5 / 5)
8- Quien comió mas galletas fue primo, que comió 35 galletas.
How much more expensive is it, per pound, to buy ground beef at Store B than at Store A?
Answer:
2.42
Step-by-step explanation:
First you need to use two points from store b to find the slope (y1-y2)/(x1-x2). I chose the first two points. (15.54-25.9)/(1.5-2.5)= 10.36. After you take another point from store b to plug into the equation y1-y2=m (x1-x2). M is the slope we just found and I used the first point.
Y1-15.54=10.36 (x1-1.5) distribute the 10.36 to the parentheses.
Y1-15.54=10.36x -15.54 get y1 by itself
Y=10.36x so store b is 10.36 a pound and store a is 7.94 a pound. 10.36-7.94= 2.42

Determine whether the sequence 12, 40, 68, 96 could be geometric or arithmetic. If possible, find the common ratio or difference.
a
It could be arithmetic with d = 28.
b
It could be arithmetic with d = –28.
c
It could be geometric with r = 28.
d
It is neither.
Answer:
A
Step-by-step explanation:
it is Arithmetic because if you subtract 12 from 40 you'll get 28 , same for the others. but if you get the common ratio by dividing 40/12 which is 3.333... it's doent work for the sequence

Brett shaded 4/8 of a sheet of notebook paper. Aisha says he shaded 1/2 of the paper. Are the two fractions equivalent? if so, what is another equivalent fraction
Answer:
The two fractions are equivalent; another equivalent fraction is 3/6
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] x 4 = 4/8, therefore the fractions are equivalent.
1/2 x 3 = 3/6 which is equivalent to 1/2.

Step-by-step explanation:
1 1/4 = 5/4
4 x 3 = 12
5/4 x 3/3 = 15/12
1/3 can be converted to 4/12
15/12 - 4/12 = 11/12

- 3x + y = 3
2y = -3x - 12
Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6

36 • (-9)
SHOW WORK PLEASE!!!
Answer:
-324
Step-by-step explanation:
First, you need to just multiply the two numbers together.
36 * 9
This would give you the overall answer. Then you determine if when you multiply the numbers, if you'd need to add the integer, a.k.a, the negative sign.
Since when you multiply a negative and a positive, the answer will be negative.
So, 36 * (-9) = -324
