The solution to -3(2 - 5x) = 3x + 12 is
1. -2.25
2. -1.625
3. 1.5
4. 3
Answer:
1.5
Step-by-step explanation:
i am not certain but this is how I got it
First distribute which gives you the -3 with 2 I switched them around so I did -3(-5x+2) and you will get 15x-6
Then the opposite of subtraction is addition so you add 6 to both sides so you add six to 12 and to 6 leaving you with 15x=3x+18 you then will subtract 3x from 15x and 3 leaving you with 12x=18 the divide the numbers
After you divide you get 3/2 then put it has a decimal and you get 1.5

Michael accidently dropped his conducting baton off the top of the bleachers while performing with the marching band at a football game. The
bleachers are 144 feet high, and the baton landed after 3 seconds. Complete the table modeling the height of the baton, h(t), after t seconds.
Answer: the first bubble is 144, the last bubble is 3
Step-by-step explanation:
at 0 seconds the height is 144. at 3 seconds the height is 0.
The required missing values in the table are (0,176) and (3.67, 0).
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The equation representing the given data in the table is given by the equation of the line,
y - y₁ =(y₂ - y₁) / (x₂ - x₁) (x - x₁)
Substitute the value in the above equation from the table.
y - 128 = (80-128)/(2-1) (x - 1)
y - 128 = -48/1(x - 1)
y = -48x + 48 + 128
y = -48x + 176
Put x = 0 in the above equation,
y = 176 feet high
Again put y = 0
0 = -48x = +176
48x = 176
x = 176 / 48
x = 3.67
Thus, the required missing values in the table is (0,176) and (3.67, 0).

Last month, Curtis bought a new mountain bike for $250. In a store advertisement, the mountain bike is on sale for $210. What is the percent of the decrease in the value of the mountain bike?
Answer:
16%
Step-by-step explanation:
say the percent decrease = x. Then
x/100 x 250 = 210.
x/2 x 5 = 210
x/2 = 210/5
x/2 = 42
x = 42 x 2
x = 84.....
BUT this is not the answer. We need 100-84=16 for the answer.
So the bike dropped 16%. Thank me later :)
If Curtis bought a new mountain bike for $250. In a store advertisement, the mountain bike is on sale for $210. Then 16% of the decrease in the value of the mountain bike
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity
Given,
Curtis bought a new mountain bike for $250.
the mountain bike is on sale for $210.
We need to find the percent of the decrease in the value of the mountain bike.
Let the percent decrease be x.
x/100 x 250 = 210.
5x/2= 210
Divide both sides by five
x/2 = 210/5
x by two equal to two ten by 5, we get x by two equal to forty two
x/2 = 42
Apply cross multiplication
x = 42 x 2
x = 84.
We need 100-84=16.
Hence 16 percent of the decrease in the value of the mountain bike

What is the relationship between the values of the given digits 7's in 7'700
Step-by-step explanation:
The given number is 7700.
We need to find the relationship between the values of the digit 7s in it.
The digit in the extreme left is 7 and second no is again 7.
The place value of first 7 is 7000
The place value of second 7 is 700.
Taking ratio of place value of 7 in first 7 and for second 7 as follows :
[tex]R=\dfrac{7000}{700}\\\\R=10[/tex]
So, value of first 7 is 10 times that of the value of second 7.
Dada una distribución t de Student con 15 grados de libertad, calcule el valor de t1 tal que a) el área a la derecha de t1 sea 0.01, b) el área a la izquierda de t1 sea 0.95, c) el área a la derecha de t1 sea 0.10, d) el área a la derecha de t1 junto con el área a la izquierda de –t1 sea 0.01, e) el área entre a –t1 y t1 sea 0.95.
Answer:
a) t₁ = 2,947
b) t₁ = 2,131
c) t₁ = 1,753
d) t₁ = 2,947 -t₁ = -2,947
e) t₁ = 2,131 -t₁ = -2, 131
Step-by-step explanation:
a) t₁ para el área a la derecha de 0,01
En la tabla t- student el t correspondiente a 0,01 es:
t₁ = 2,947
b) t₁ para el área a la izquierda sea de 0,95. Es igual al t para el cual el área de la drecha es 0,05
t₁ = 2,131
c) t₁ para que el área de la derecha sea 0,10
t₁ = 1,753
d) Buscar t₁ para el cual las áreas de derecha de (t₁) más la de la izquierda de (- t₁ ) sea 0,01.
Si el área es de 0,01 quere decir que la mitad, es decir 0,005 es el área para una cola, luego
t₁ = 2,947 y -t₁ = -2,947
e) Para que el área entre - t₁ y t₁ sea 0,95
t₁ = 2,131 y -t₁ = -2, 131
The lengths of the sides of a triangle are in the extended ratio 7: 9 : 10. The perimeter of the triangle is 52 cm. What are the lengths of the sides?
Answer:
14 cm, 18 cm, 20 cm
Step-by-step explanation:
7x + 9x + 10x = 26x
equation: 26x = 52
divide each side by 26: x = 2
7 * 2 = 14
9 * 2 = 18

If 4/5 – 3/10 = x + 11/2, find the value of
X.
Answer:
x = 85/60 or 17/12
Step-by-step explanation:
4/5 - 3/10 = x + 11/12
=> 8/10 - 3/10 = x + 11/12
=> 5/10 = x - 11/12
=> x - 11/12 = 5/10
=> x = 5/10 + 11/12
=> x = 5 * 6 / 10 * 6 + 11 * 5 / 12 * 5
=> x = 30 / 60 + 55/60
=> x= 85/60

B) 176 ft²
Step-by-step explanation:
Answer:
39.53 ft2
Step-by-step explanation:
If you are having a hard time with this it is most likely due to the semicircle. First you need to divide the diameter (3) by 1/2, next you multiply the now radius (radius is always 1/2 of the diameter) and pi to get 3.53.
Now you have to find the area of the rectangle, 3*12 = 36.
36 + 3.53 = 39.53 rounded.

a. If sea level is represented by 0, then something below sea level would be a value of something less than zero, a negative number. Because the Challenger Deep is 35,814 feet below sea level, it will be represented by -35,814.
b. Trieste is trying to reach the bottom of the challenger deep, which is y, and descending the ocean at -3 feet per second. So the equation would be like this
-35,814 = -3x
We are just looking for x. Notice how both number values are negative so the time it would take Trieste to reach the bottom would be a positive value.
-35,814 divided by -3 = 11938, so it would take 11938 seconds to reach the bottom.
c. y and x would be used in the same context as it would just now. Except that Trieste is coming up to the surface, so the depth of the Challenger Deep is positive.
35814 = k * 11938
k = 3, the amount of time it took to reach the surface in hours.

Hello friend!!!
here's ur answer
1) <y = 180 - 74 = 106° ( linear pair )
<x = <y ( alternate angles )
therefore, <x = <y = 106°
2) <x = 68° ( corresponding angles )
<y = 180 - 68 = 112° ( linear pair )
<z = 112° ( vertically opposite angles )

Hence, It is not between the numbers - 8.423 and - 8.395.
Clearly, - 8 1/2 is less than - 8.423 and - 8.395.
Hence, It is not between the numbers - 8.423 and - 8.395.
Clearly, - 8 2/5 = - 8.4 is in between - 8.423 and - 8.395.
Hence, It is between the numbers - 8.423 and - 8.395.
