Step-by-step explanation:
Remark
I'm going to assume that the edges of the cubes are 1/2 inch on each side.
V = 1/2 * 1/2 * 1/2 = 1/8 cubic inches.
Volume of the box
V = L * w * h
Givens
L = 2 inches
w = 3.5 inches
h = 5.5 inches
Solution
V = L * w * h
V = 2 * 3.5 * 5.5
V = 38.5
1/8 has the decimal equivalent value of 0.125
Number of cubes needed = Volume of the box / volume of the cube
Number of cubes needed = 38.5 / 0.125
Number of cubes needed = 308

–19w + 11 = –17w − 19
w=
Please help, will mark brainliest to correct answer!
Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15

The third term in an arithmetic sequence is 9 and the fifth term is 21 . If the first term if a1, which is an equation for the nth term of this sequence?
A:an=6n-9
B:an=14n+6
C:an=6n+14
D:an=9n-6
Answer:
A: an = 6n - 9
Step-by-step explanation:
third term in an arithmetic sequence is 9
a3 = a + 2d
a + 2d = 9
the fifth term is 21
a5 = a + 4d
a + 4d = 21
a + 2d = 9 (1)
a + 4d = 21 (2)
Subtract (1) from (2) to eliminate a
4d - 2d = 21 - 9
2d = 12
d = 12/2
d = 6
Substitute d = 6 into (1)
a + 2d = 9 (1)
a + 2(6) = 9
a + 12 = 9
a = 9 - 12
a = -3
nth term of this sequence = a + (n - 1)d
= -3 + (n - 1)6
= -3 + 6n - 6
= 6n - 9
an = 6n - 9
A jacket sells for $24.99. All the merchandise in the store is on sale at a 25% discount. If the sales tax is 8%, what will a customer pay for the jacket?
Answer:
$20.24
Step-by-step explanation:
Since the 25% discount takes off a quarter of the price, we multiply 24.99 by 3/4
24.99 x 3/4 = 18.74
So with the discount and without tax, the cost of the jacket is 18.74
Then we add 8% for sales tax
8% of 18.74 is $1.50
18.74 + 1.5 = 20.24
So the final cost of the jacket is $20.24

Solve by Elimination:
x - 2y = 4
X - 1y = 2
its urgent
Answer:
x = 0 and y = -2
Step-by-step explanation:
x - 2y = 4 and X - 1y = 2
you mentioned elemination aka substraction
so you when substract x - x = 0 -2y -( -y) = -y and 4 -2 = 2
so - y = 2
or y = 2
now substitute the numbers
x + 4 = 4
x = 0
and try it with one of the equation or sometimes trying on both of them can be very helpful

3. A sprinkler rotates 75°, pauses, and then rotates another 75°, How many degrees did it rotate altogether?
0 degrees
140 degrees
150 degrees
160 degrees
Help?
Answer: 150 degrees
Step-by-step explanation:
The number of degrees did it rotate altogether should be considered as the 150 degrees.
Calculation of the number of degrees:Since A sprinkler rotates 75°, pauses, and then rotates another 75
So, here total degrees be like
= 75 degrees + 75 degrees
= 150 degrees
hence, The number of degrees did it rotate altogether should be considered as the 150 degrees.

1A. Nayeli wants to earn some extra money so she sells lemonade for $2 per cup and orange juice for $3 per cup. She sells a total of 100 cups and earns $240. Later she wants to find the number of cups of lemonade and the number of cups of orange juice she sold. Which system of equations below represents this situation?
1. 2x + 3y = 240 AND x + y = 100
2. 2x + 3y = 100 AND x + y = 240
3. x + 2y = 100 AND 3x + y = 240
4. 2x + 100 = 240.AND x = 3y
1B. In the context of the problem, what does your solution (x,y) mean? Fill in the blanks for the solution sentence below: Nayeli sold ____ cups of lemonade and ____ cups of orange juice. Write your answer in this form: 20, 40
Answer:
1. 2x + 3y = 240 AND x + y = 100
Nayeli sold 60 cups of lemonade and 40 cups of orange juice.
Step-by-step explanation:
Let
Number of cups of lemonade sold = x
Number of cups of orange juice sold = y
The system of equation could be represented by:
2x + 3y = 240 (1)
x + y = 100 (2)
from (2)
x = 100 - y
Substitute into (1)
2x + 3y = 240 (1)
2(100 - y) + 3y = 240
200 - 2y + 3y = 240
- 2y + 3y = 240 - 200
y = 40 cups
Substitute y = 40 into (2)
x + y = 100 (2)
x + 40 = 100
x = 100 - 40
x = 60 cups
Nayeli sold 60 cups of lemonade and 40 cups of orange juice.
(x, y) = (60, 40)

3. Which of the following equations would not have a solution that is the same as the solution to the system
shown below
2x + 3y = 1. x-y=5
(1) 3x+2y=6
(3) 5y=-9
(4) 2x-2y=5
(2) 4x+6y=2
Answer:
A
Step-by-step explanation:
The solution that is not the same as the solutions to the system of equations is 2x - 2y = 5.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
2x + 3y = 1 _____(1)
x - y = 5 _______(2)
From (1) and (2) we get,
x = 5 + y
2 (5 + y) + 3y = 1
10 + 2y + 3y = 1
10 + 5y = 1
5y = -9
y = -9/5
Now,
x = 5 - 9/5
x = (25 - 9)/5
x = 16/5
The solutions are x = 16/5 and y = -9/5.
Now,
(1) 3x + 2y=6
3 x (16/5) + 2 x (-9/5) = 6
48/5 - 18/5 = 6
30/5 = 6
6 = 6
(2) 5y = -9
5 x (-9/5) = -9
-9 = -9
(3) 2x - 2y = 5
2 x (16/5) - 2 x (-9/5) = 5
32/5 + 18/5 = 5
50/5 = 5
10 ≠ 5
(4) 4x + 6y = 2
4 x (16/5) + 6 x (-9/5) = 2
64/5 - 54/5 = 2
10/5 = 2
2 = 2
Thus,
3x+2y=6, 5y=-9, and 4x+6y=2 have the same solutions.
