Hello!
To solve this, you need to distribute and combine like terms.
Like terms are equivalent types of numbers for example;
2x and 3x are like terms, so if the equation said 2x - 5 + 3x, you would only combine 2x and 3x.
If the equation said 5 + 9 - x, you add the like terms, 5 + 9, and the simplification would be 14 - x.
Distribution is when you multiply the number outside the parenthesis into the parenthesis. for example, if an equation says, 5(x-2) = y, you would multiply 5 on the numbers x and -2, resulting in the equation, 5x - 10 = y.
--------Now lets work on your math problem.
Step 1, right the equation, 7(-9a-3)-2a7(−9a−3)−2a
Step 2: distribute numbers (remember multiplying)
7(-9a-3)-2a7(−9a−3)−2a
For the first distribution, 7(-9a-3)-2a7(−9a−3)−2a
you multiply 7 to the numbers in the parenthesis,
resulting in,
-63a - 21
Second distribution is, 7(-9a-3)-2a + 7(−9a−3)−2a
in which you multiply -7 into the numbers in the parenthesis resulting in;
-63a - 21
(did you type the equation twice if so, there are now two problems i need to solve.)
now add like terms -2a + -2a = -4a
-63a - 21 + -63a - 21 = -126a - 42
-126a - 4a - 42
Answer is -130a - 42.
If your equation was actually this, : 7(-9a-3)-2a
Then the answer would have been, -65a - 21
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.
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
4. Tabatha is dining out at Mandee's and decides to get an order of curly fries.
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

Joan got fast food for lunch. Joan paid $2.41 on a salad and $2.15 on a sandwich
with a $10 bill. Joan got a combo deal. What was the change from the purchase?
Hello :D
To do this you need to add up the cost of the sandwich and salad.
$2.41 + $2.15 = $4.56
$10.00 - $4.56 = $5.44
The answer is $5.44. I hope this helps :)

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

Determine if 0.34375 is rational or irrational and give a reason for your answer.
Answer:
Rational
Step-by-step explanation:
The key detail in this problem is that the decimal is terminating so it's not infinitely continuous. A irrational number is a value that when in decimal form, it is infinitely continuous and never ends. Since the decimal we are working with terminates, it is rational.

2. 6 and 54 [3]
3. 68 and 3 [4]
4. 10and 40 [5]
5. 1⁄2 and 2 [2]
The complete Arithmetic Sequence for each of the sequences are;
1) 2, 17, 32
2) 6, 18, 30, 42, 54
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

A box of candy was divided into three bottles P, Q and R in the ratio 9:4:11. If, instead, the candy had been divided equally between them, there would be 21 fewer pieces of candy in bottle R. How many pieces of candy were there in the box?
There are a total of 44 candies in the box.
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

(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.
