Landon bought 4 pounds of walnuts for $10.92. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of walnuts, x?
Answers
Step-by-step explanation:
The constant of proportionality is the ratio of the cost to the number of pounds of walnuts. In other words, it is the price of one pound of walnuts.
$10.92 / 4 lb = $2.73 / lb
The constant of proportionality that relates the cost in dollars, y, to the number of pounds of walnuts, x is $2.73 lb
What is constant of proportionality?Firstly, there is proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called constant of proportionality.
The constant of proportionality can be calculated as the ratio of the cost to the number of pounds of walnuts.
x = number of walnuts
y = cost of walnutsin dollars
In other words, it is the price of one pound of walnuts now we have;
Constant of proportionality =$10.92 / 4 lb = $2.73 / lb

If an airplane travels at an average speed of 510 mph, how far does the airplane move in 50 minutes?
Answers
Answer:
425 miles
Step-by-step explanation:
Divide 510 by 60 to get miles per minute and then multiply by 50 to get miles in 50 minutes
The airplane move 425 miles in 50 minutes.
what is Speed- Distance Formula?Speed = Distance/TimDistance = Speed X Time, and Time = Distance / SpeedGiven:
Speed= 510 mph
Time= 50 min = 50/60 hour.
So, speed= Distance / Time
510 = Distance / (5/6)
510 x 5/6 = Distance
Distance = 425 miles
Hence, the Airplane travel 425 miles.

solve for x -5(-x+1)-3x-1=-12
Answers
Answer:
x = -2
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define equation
x - 5(-x + 1) - 3x - 1 = -12
Step 2: Solve for x
Distribute -5: x + 5x - 5 - 3x - 1 = -12Combine like terms: 3x - 6 = -12Add 6 to both sides: 3x = -6Divide 3 on both sides: x = -2Step 3: Check
Plug in x to verify it's a solution.
Substitute: -2 - 5(-(-2) + 1) - 3(-2) - 1 = -12Multiply: -2 - 5(2 + 1) + 6 - 1 = -12Add: -2 - 5(3) + 6 - 1 = -12Multiply: -2 - 15 + 6 - 1 = -12Subtract: -17 + 6 - 1 = -12Add: -11 - 1 = -12Subtract: -12 = -12Justin uses į of a gallon of paint to cover of his bedroom wall.

Dai is comparing how many trading cards he has with his friend Maura. Initially, they find that Dai has four more cards than twice the number that Maura has. Part B) If Dai must give Maura 8 cards so that they have the same amount, set up and solve an equation to determine the number of cards Maura initially had.
Answers
Answer:
Maura had 12 cards initially
Step-by-step explanation:
Represent Dai's card with D and Maura's card with M.
From the first statement, we understand that:
D = 4 more that twice of M
This is represented as:
D = 4 + 2M
From the second statement, we understand that.
When 8 is subtracted from D, M is increased by 8 and both are equal.
This is represented as:
D - 8 = M + 8
Hence, the equations of the system is:
D = 4 + 2M
D - 8 = M + 8
Substitute 4 + 2M for D in the second equation
4 + 2M - 8 = M + 8
Collect like terms
2M - M = 8 - 4 + 8
M = 12
To solve for D, we simply substitute 12 for M in D = 4 + 2M
D = 4 + 2 * 12
D = 4 + 24
D = 28
Hence, Maura had 12 cards initially

1. Which expression has a value of 30 when x = -1 and y = 3? A. (x - 3^2) · y - 6 B. (x - 3^2) · (y - 6) C. x - 3^2 · (y - 6) D. x - 3^2 · y - 6
Answers
Answer:
B. (x - 3²)(y-6)
Step-by-step explanation:
Find the expression with a value of 30;
when x = -1 and y = 3:
A. (x - 3²).y-6
(-1 - 9).3-6 = -10 x 3 -6 = -30 - 6 = -36
B. (x - 3²)(y-6)
( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30
C. x - 3² . (y-6) = -1 - 9.(3-6)
= -1-9.-3
= -1 - 9 x -3
= -1 + 27
= 26
D. x - 3².y-6 = -1 - 9. 3 - 6
= -1 - 27 - 6
= -34
