Answer:
Y=-1
Step-by-step explanation:
-4(y-2)
-4y+8=12
-8. -8
-4y=4
-4. -4
y=-1
Answer: Y = -1
Step-by-step explanation:
This is solved using the distributive property.
1. Distribute, so now it should look like -4y + 8 = 12
2. Now subtract the 8 from both sides to isolate -4y = 4
3. Divide -4 on both sides to get y = -1

What is 2/5 divided 1/3
Answer:
1.33
Step-by-step explanation:
Answer:
1 and 1/5
Step-by-step explanation:
2/5 divided by 1/3, so keep change flip applies to this so keep 2/5 change division to multiplication and flip 1/3 to 3/1 that changes the equation to 2/5 times 3/1 and that equals 1 and 1/5
Element X decays radioactively with a half life of 6 minutes. If there are 260 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 113 grams
Answer:
7.2 minutes
Step-by-step explanation:
The formula to find the time using the radioactive decay rate formula is given as:
t = t½ × In(Nt/No)/-In2
Where
t½ = half life = 6 minutes
No = Initial Amount = 260 grams
Nt = Amount after decay
= 113 grams
Hence:
t = 6 × In(113/260)/-In2
t = 7.2131331036796 minutes
Approximately = 7.2 minutes

James drove to the lake and back the trip there took four hours and the trip back took six hours he average 20 mph faster on the trip there on on the return tip find Jameses average speed on the trip
Answer: 60 mph
Step-by-step explanation:
Question wants the speed to the lake.
It took James 4 hours to get to the lake and he drove at a speed 20 mph faster than when he came back.
It took him 6 hours to come back.
Assuming the speed James used on the return trip is x:
Expression for distance is:
4(x + 20) = 6x
4x + 80 = 6x
2x = 80
x = 80/2
x = 40 mph
Speed to the lake = 40 + 20
= 60 mph
is a percent a constant of proportionality
Answer:
Yes.
Step-by-step explanation:
A percent can be represented as a fraction and a fraction is a constant of proportionality.

Binda is working on an art project that requires 32 feet of ribbon. She has 17 1/2 feet of ribbon, but needs to purchase more ribbon to have enough to finish her art project. All of the ribbon will be cut into piece that are 1/4 foot long. Write and solve an equation that can be used to determine the number of feet of ribbon, x, that Binda needs to purchase to finish her art. How many 1/4 foot pieces of ribbon can Binda make from all 32 feet of ribbon?
Answer:
x + 17.5 = 32 (subtract 17.5 from 32 to get your answer)
14.5 feet of ribbon Binda needs to purchase
32 / 0.25 = 128 pieces of 1/4 foot ribbon
Answer:
x + 17.5 = 32 (subtract 17.5 from 32 to get your answer)
14.5 feet of ribbon Binda needs to purchase
32 / 0.25 = 128 pieces of 1/4 foot ribbon

Which expression is equal to (7 * 2) 2?
A)(7 + 2) × 2
B)(2x2)+7
C)7x(2 x 2)
D)(2 x 7) + (2x2)
Answer:
C. 7 * (2 * 2)
Step-by-step explanation:
Figure out the original expression to see the equivalent expression.
(7 * 2) * 2
14 * 2
28
We have to look for an expression that equals 28.
A is (7 + 2) * 2.
(7 + 2) * 2
9 * 2
18
A equals 18, so it's not equivalent to the original expression.
Now B, which is (2 * 2) + 7
(2 * 2) + 7
4 + 7
11
B equals 11, so it is also not equivalent.
Now C; that is 7 * (2 * 2)
7 * 4
28
C equals 28, so that is equivalent. Although we have found our answer, we need to make sure it's right by evaluating D. ((2 * 7) + (2 * 2))
(2 * 7) + (2 * 2)
14 + 4
18
D, like A, equals 18, so it is also incorrect.
C is the only expression that is equivalent to (7 * 2) * 2, so it is the answer.
A: x/8=3/4
B: 2/5=x/40
C: 1/8=x/40
D:x/10=12/15
Which expression gives the distance between the points
(2,3) and (4, -3)?
O A. (2-4)* +(3+3)
O B. (2-3)* +(4+3)?
C. (2-4)2 + (3+3)2
O D. (2-3)* +(4 +3)
SUBMIT
Answer:
C
Step-by-step explanation:
The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is
d = √[(x2 - x1)² + (y2 - y1)²]
Here (x2, y2) = (2, 3) and (x1, y1) = (4, -3)
Plugging them gives us
d = √[(2 - 4)² + (3 - (-3))²]
d = √[(2 - 4)² + (3 + 3)²]
You'd like your pendulum to take 20 seconds to complete a cycle. How long will the pendulum need to be? Is this reasonable in your building, which is planned to be 20 feet high
Answer:
It would need to be 324.23 feet high (not reasonable)
Step-by-step explanation:
If you plug it into the pendulum formula given T = 2 π √(L/32), all you would have to do is set T=20 and solve for L
You would end up getting 3200/(π²)
this is equal to 324.227
This was the formula given to me by the assignment, not sure if it is the same on yours. Good luck! ;)
A leaking faucet drips into a bucket. The faucet drips at a constant rate. The level of water in the bucket rises
3 inches in 6 hours. What was the rate per hour of the water level change?
Answer:
The per hour rate is 0.5 inches per hour
Step-by-step explanation:
Here, we want to calculate the rate at which the level of the water increased
Mathematically, we can get this by dividing the amount of increment by the time it took
That would be 3 inches divided by 6 hours
= 3/6 = 0.5 inches per hour

When you reverse the digits in a certain 2 digit number you decrease its value by 81. What is the number if the sum of its digits is 9?
Answer: 90 is a number which has 9 as the sum of its digits, 9+0=9 and if the digits are reversed, 09 is 81 less than 90.
Step-by-step explanation: Since the number must be a 2-digit number, it seems that 90 is the only number that qualifies.
If you need some equations, here is a way to set up a system to solve:
x+y= 9 rewrite to get a value for y to substitute:
y = 9-x
10x +y = 10y + x + 81 rewrite by moving (subtracting variable terms from both sides)
10x -x + y-10y = 81 combine like terms
9x - 9y = 81
Substitute for y and solve for x
9x - 9(9-x)= 81 distribute.
9x - 81 + 9x = 81
18x = 162. 162/18 = 9
x = 9
Substitute in the original equation to solve for y
9 + y = 9
y = 0
10(9) + 0 = 10(0) + 9 +81
90 - 81 = 09

Alicia, Quentin, and Rosalyn are siblings. Alicia is the oldest sibling. Quentin is four years younger than Alicia. Rosalyn is two years older than Quentin. The sum of the siblings’ ages, in years, is 48. How old is Alicia?
Answer:
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
Step-by-step explanation:
Let the age of Alicia be x
Let the age of Quentin be y
Let the age of Rosalyn be z
If the sum of the siblings’ ages, in years, is 48 then;
x+y+z = 48.... 1
If Rosalyn is two years older than Quentin then;
z =y+2 ..... 2
Also if Quentin is four years younger than Alicia then;
y = x-4 ... 3
From 3:
x = y+4 ... 4
Substitute 2 and 4 into 1 to have:
y+4+y+y+2 = 48
3y + 6= 48
3y = 48-6
3y= 42
y = 14
Since x= y+4
x = 14+4
x = 18
Since z = y+2
z = 14+2
z = 16year
This means that;
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
