7x-(6x-1)=2. What is the answer?
Answer:
x=1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x−(6x−1)=2
7x+−1(6x−1)=2(Distribute the Negative Sign)
7x+−1(6x)+(−1)(−1)=2
7x+−6x+1=2
(7x+−6x)+(1)=2(Combine Like Terms)
x+1=2
x+1=2
Step 2: Subtract 1 from both sides.
x+1−1=2−1
x=1

what is the value of 10x^3 y^2 when x=-2 and y=-3
Answer:
-720
Step-by-step explanation:
We are given the expression:
[tex]10x^3y^2[/tex]
and asked to evaluate when x= -2 and y= -3.
Therefore, we must substitute -2 for x and -3 for y.
[tex]10(-2)^3*(-3)^2[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Evaluate the first exponent.
⇒ (-2)³ = -2 * -2 * -2= 4*-2= -8
[tex]10(-8)*(-3)^2[/tex]
Evaluate the second exponent.
⇒ (-3)²= -3 * -3= 9
[tex]10(-8)*9[/tex]
Multiply 10 and -8.
[tex]-80*9[/tex]
Multiply -80 and 9.
[tex]-720[/tex]
The value of 10x³y² at x= -2 and y= -3 is -720

PLEASE HELP Solve for w and simplify your answer.
Answer:
see below (I hope this helps!)
Step-by-step explanation:
To get rid of the coefficient of w, 3/2 in this case, we must divide the entire equation by 3/2, which is the equivalent of multiplying the entire equation by 2/3. Doing this, we get:
3/2w * 2/3 = -20 * 2/3
w = -40/3 = [tex]-13\frac{1}{3}[/tex]
A used bookstore sells hardback books and paperback books.A hardback book costs $11, including tax.A paperback book costs $5, including tax.Jamal bought 3 more paperback books than hardback books.Jamal spent $47. How many paperback books did Jamal buy? A.2 B.3 C.4 D.5
Answer:
D.5
Step-by-step explanation:
You can write the following equations from the information given:
y=x+3 (1)
11x+5y=47 (2)
x is the number of hardback books
y is the number of paperback books
You can replace (1) in (2):
11x+5(x+3)=47
11x+5x+15=47
16x=47-15
16x=32
x=32/16
x=2
Then, you can replace the value of x in (1) to find the value of y:
y=2+3
y=5
According to this, the answer is that Jamal bought 5 paperback books.
Mrs. Bell has an interest rate of 4.175% on her house. Mr. Bentley has an interest rate of 4.25% on his house. Which explains who has the lower interest rate?
Answer: Mrs Bell
Step-by-step explanation:
From the question, we are informed that Mrs. Bell has an interest rate of 4.175% = 0.04175 on her house and Mr. Bentley has an interest rate of 4.25% = 0.0425 on his house.
The person who has the lower interest is Mrs Bell. This is because 4.25% is higher than Mrs Bell's interest of 4.175%
Answer:
The answer is D
Step-by-step explanation:
Mrs bell has the lower interest rate because both decimals have a 4 in the ones place, and 1 tenth is less than 2 tenths.

Answer:
technically, unless it says somewhere that each ticket cost $1 none would be correct, but the answer your looking for is student B
Step-by-step explanation:
Answer:
im pretty sure student b is correct
because every 10 tickets they give away 5 dollars you replace y as 10 and 1/2 of 10 is 5 so you replace the 1/x with 5
btw im not 100% sure im correct

9:25 y 33:41:38 a que unidades de tiempo se refieren?
Answer:
Se refieren a las unidades de tiempo del sistema sexagesimal
9:25 son 9 minutos y 25 segundos
33:41:38 son 33 horas, 41 minutos y 38 segundos.
Step-by-step explanation:
El sistema sexagesimal se utiliza para medir tiempos y ángulos.
El tiempo se mide en horas,minutos y segundos
En cambio, los ángulos se miden en grados,minutos y segundos.
Los dos puntos '':'' sirven para separar las unidades.
La base de este sistema es el número 60 :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 hora
Eso en cuanto a tiempo
En cuanto a grados :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 grado
Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos
Entonces, 9:25 son 9 minutos y 25 segundos
Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).
Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.

What is the volume of the cube below?
A. 4x2
B. 16
C. 4x
D. 16x2
Answer:
a.
Step-by-step explanation:
The volume of cube 4x².
What is Volume?Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.
We have,
Edges of cube as = 4 , x and x.
So, volume of cube
= 4 x (x . x)
= 4 . x²
= 4x²
Thus, the volume of cube 4x².

Select each pair of functions that are inverses of each other. f (x) = left-brace (negative 5, negative 9), (negative 3, negative 4), (0, 1), (3, 7), (6, 13) right-brace. G (x) = left-brace (negative 9, negative 5), (negative 4, negative 3), (1, 0), (7, 3), (13, 6), right-brace. f (x) = x + 7; g (x) = x minus 7 2 2-column tables with 4 rows. Table 1 is titled f (x). Column 1 is labeled x with entries 2, 3, 4, 5. Column 2 is labeled y with entries 3, 8, 15, 24. Table 2 is titled g (x). Column 1 is labeled x with entries 5, 4, 3, 2. Column 2 is labeled y with entries 24, 15, 8, 3.
Answer:
The first two pairs of functions are inverse of each other
Step-by-step explanation:
Inverse functions?
1...................................
f(x) = {(-5, -9), (-3, -4), (0,1), (3,7), (6,13)}
g(x) = {(-9,-5), (-4, -3), (1,0), (7,3), (13,6)}
Yes, this pair is inverse as all points of the functions have inverse values2...................................
f(x) = x + 7 is given
Inverse of f(x) is
x = f'(x) + 7 ⇒ f'(x) = x - 7Since g(x) = x - 7 it is inverse with f(x)
Yes, this pair is inverse as described above3...................................
Data of f(x) and g(x)
x = {2, 3, 4, 5} f(x) = {3, 8, 15, 24}
x = {5, 4, 3, 2} g(x) = {24, 15, 8, 3}
No, as both functions have same domain and rangeexample is f(2) = 3 and g(2) = 3 as per tableThe price of an item has been reduced by 80% the original price was $20. What is the price of the item now ?
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

solve for the missing missing variable C=2πr; C=18.84, π=3.14
Answer:
The missing variable r = 3
Step-by-step explanation:
C = 2πr
Where,
C = 18.84
π = 3.14
r= ?
The missing variable is r
C = 2πr
Making r the subject
r = C / 2π
= 18.84 / 2*3,14
= 18.84 / 6.28
= 3
r = 3
The missing variable r = 3
Check:
C = 2πr
18.84 = 2*3.14*3
18.84 = 18.84
