8 x 6 = (4 6) + (
x6)
= 24 +
Answer:
4,24,48
Step-by-step explanation:
For the first equation, they are splitting 8 in half. So 8/2 would be 4. The 4 would go in the first box.
Then 4x6 is 24 in the second box.
Then just add 24 and 24. 24+24=48
And your last answer is 48.
the length of a new rectangular playing field is 9 yards longer than double the width. if the perimeter of the rectangular playing field is 288 yards, what are it's dimensions?
Answer:
Step-by-step explanation:
Width = w
Length =2w + 9
Perimeter = 288 yards
2*(length + width) = 288
2*(2w + 9 + w) = 288
2*(2w + w +9) = 288 {Combine like terms}
2*(3w + 9 ) = 288
2*3w + 2*9 = 288 {Use distributive property}
6w + 18 = 288 {Subtract 18 from both sides]
6w = 288 - 18
6w = 270 {Divide both sides by 6}
w = 270/6
w = 45 yards
Length = 2*45 + 9 = 90 +9 = 99 yards
Length = 99 yards
Width = 45 yards

3) 68, 55, 42, 29, 16, 3
4) 10, 15, 20, 25, 30, 35, 40
5) ½, 1, 3/2, 2
How to solve arithmetic sequence?
1. Using the formula for the nth term of an arithmetic sequence:
a_n = a₁ + (n - 1)d , find d.
a₁ = 2 n = 3
a_n = a₁ + (n – 1)d
32 = 2 + (3 – 1)d
32 = 2 + (2)d
32 = 2 + 2d
32 – 2 = 2d
30 = 2d
30/2 = 2d/2
15 = d
Using d = 15, find a₂.
a₂ = a₁ + (2 – 1)15
a₂ = 2 + (1)15
a₂ = 2 + 15
a₂ = 17
2. Using the formula for the nth term of an arithmetic sequence:
a_n = a₁ + (n - 1)d , find d.
a₁ = 6 n = 5 a_n = 54
a_n = a₁ + (n – 1)d
54 = 6 + (5 - 1)d
54 = 6 + (4)d
54 = 6 + 4d
54 - 6 = 4d
48 = 4d
48/4 = 4d/4
12 = d
Using d = 12, find a₂, a₃, and a₄.
a₂ = a₁ + (n - 1)d a₃ = a₁ + (n - 1)d a₄ = a₁ + (n - 1)d
a₂ = 6 + (2 - 1)12 a₃ = 6 + (3 - 1)12 a₄ = 6 + (4 - 1)12
a₂ = 6 + (1)12 a₃ = 6 + (2)12 a₄ = 6 + (3)12
a₂ = 6 + 12 a₃ = 6 + 24 a₄ = 6 + 36
a₂ = 18 a₃ = 30 a₄ = 42
3. Using the formula for the nth term of an arithmetic sequence:
a_n = a₁ + (n - 1)d , find d.
a₁ = 68 n = 6 a_n = 3
a_n = a₁ + (n – 1)d
3 = 68 + (6 - 1)d
3 = 68 + (5)d
3 = 68 + 5d
3 - 68 = 5d
-65 = 5d
-65/5 = 5d/5
-13 = d
Using d = -13, find a₂, a₃, a₄ and a₅.
a₂ = a₁ + (n - 1)d a₃ = a₁ + (n - 1)d a₄ = a₁ + (n - 1)d
a₂ = 68 + (2 - 1)-13 a₃ = 68 + (3 - 1)-13 a₄ = 68 + (4 - 1)-13
a₂ = 68 + (1)-13 a₃ = 68 + (2)-13 a₄ = 68 + (3)-13
a₂ = 68 - 13 a₃ = 68 - 26 a₄ = 68 - 39
a₂ = 55 a₃ = 42 a₄ = 29
a₅ = a₁ + (n - 1)d
a₅ = 68 + (5 - 1)-13
a₅ = 68 + (4)-13
a₅ = 68 - 52
a₅ = 16
4. Using the formula for the nth term of an arithmetic sequence:
a_n = a₁ + (n - 1)d , find d.
a₁ = 10 n = 7 a_n = 40
a_n = a₁ + (n – 1)d
40 = 10+ (7 - 1)d
40 = 10 + (6)d
40 = 10 + 6d
40 - 10 = 6d
30 = 6d
30/6 = 6d/6
5 = d
Using d = 6, find a₂, a₃, a₄ a₅ and a₆.
a₂ = a₁ + (n - 1)d a₃ = a₁ + (n - 1)d a₄ = a₁ + (n - 1)d
a₂ = 10 + (2 - 1)5 a₃ = 10 + (3 - 1)5 a₄ = 10 + (4 - 1)5
a₂ = 10 + (1)5 a₃ = 10 + (2)5 a₄ = 10 + (3)5
a₂ = 10 + 5 a₃ = 10 + 10 a₄ = 10 + 15
a₂ = 15 a₃ = 20 a₄ = 25
a₅ = a₁ + (n - 1)d a₆ = a₁ + (n - 1)d
a₅ = 10 + (5 - 1)5 a₆ = 10 + (6 - 1)5
a₅ = 10 + (4)5 a₆ = 10 + (5)5
a₅ = 10 + 20 a₆ = 10 + 25
a₅ = 30 a₆ = 35
5. Using the formula for the nth term of an arithmetic sequence:
a_n = a₁ + (n - 1)d , find d.
a₁ = 1/2 n = 4 a_n = 2
a_n = a₁ + (n – 1)d
2 = 1/2+ (4 - 1)d
2 = 1/2 + (3)d
2 = 1/2 + 3d
2 - 1/2 = 3d
3/2 = 3d
3/2/3 = 3d/3
1/2 = d
Using d = 1/2, find a₂, and a₃.
a₂ = a₁ + (n - 1)d a₃ = a₁ + (n - 1)d
a₂ = 1/2 + (2 - 1)1/2 a₃ = 1/2 + (3 - 1)1/2
a₂ = 1/2 + (1)1/2 a₃ = 1/2 + (2)1/2
a₂ = 1/2 + 1/2 a₃ = 1/2 + 1
a₂ = 1 a₃ = 3/2

(50 Points) ∠1 and ∠2 are supplementary angles. m∠1 is 4y+7, and m∠2 is 9y+4. Find m∠2.
∠1 and ∠2 are supplementary angles. m∠1 is 4y+7, and m∠2 is 9y+4. Find m∠2.
Solution:The sum of supplementary angle is 180°
First, solve for the value of y.
∠1 + ∠2 = 180°(4y + 7) + (9y + 4) = 180°13y + 11 = 180°13y = 180° - 1113y = 169/13y = 13°Then, plug and substitute the value y = 13 to find the m∠2.
m∠29y + 49(13) + 4117 + 4121Answer:The angle of m∠2 is 121The measure of angle 2 is 121 degrees.
Given:
[tex]m\angle1=4y+7\\m\angle2=9y+4[/tex]
Recall: Supplementary angles are angles whose sum equals [tex]180^{o}[/tex]
To solve this problem, create an equation to find the value of x:
Thus:
[tex]m\angle1 +m\angle2=180[/tex]
Therefore:
[tex](4y+7)+(9y+4) = 180\\[/tex]
Solve for y:
[tex]4y+7+9y+4 = 180\\\\[/tex]
Add like terms:
[tex]13y+11 = 180\\\\[/tex]
Subtract 11 from both sides
[tex]13y+11 - 11= 180 - 11\\13y = 169[/tex]
Divide both sides by 13
[tex]\frac{13y}{13} = \frac{169}{13} \\y = 13[/tex]
Find the m∠2 by substituting [tex]y = 13[/tex] into [tex]9y +4[/tex]
[tex]m\angle= 9(13)+4\\m\angle = 121^{o}[/tex]
Therefore, m∠2 = 121 degrees.

chicken fingers, and a coca-cola. The total cost of the food with sales tax came to
$18.61. If Tabatha decides to give the cashier a 20% gratuity (tip), what does ber
total bill come to?
Answer:
$22.33
Step-by-step explanation:
A 20% tip would be 0.20. Multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total amount including tip.
subtotal --> $18.61
tip --> $3.72
18.61 x 0.20 = 3.72
total --> $22.33

How many pieces of candy were there in the box?The total ratio is 24
Let;
the total number of candies be xthe number of candies in R be11/22 * x = y ---- (1)
If the candies were shared equally
The ratio of candies in R will be 6
6/24 * x = y - 11 --- (2)
substitute y = 11/22 * x in (2)
6x/24 = 11x/22 - 11
x/4 = x/2 - 11

if each side of a square classroom is 25 feet then what is the perimeter of the room? what is the area of the floor of the room?
Answer:
P = 100
Area = 625
Step-by-step explanation:
Area = s^2
sqrt(area) = sqrt(s^2)
area = 25*25
sqrt(25*25) = sqrt(s^2)
s = 25
P = 4*s
P = 4 * 25
P = 100
Area = s^2
s = 25
Area = 25^2
Area = 625
