a - 6 - 6a = 4
find the value of a
Answer:
-2
Step-by-step explanation:
a - 6 - 6a = 4
a-6a=10
-5a=10
a=10/-5
a=-2
Answer:
a = -2
Step-by-step explanation:
Add like terms:
a - 6 - 6a = 4
-5a - 6 = 4
Solve for a:
-5a = 10
a = -2
So, a = -2

1. Rút gọn biểu thức A(x) = (x+2)(x+3)(x+5) - (x-1)(x+4)(x+7). Từ đó tìm tất cả các giá trị x sao cho A(x) = 0.
x = -29/7
Step-by-step explanation:
A(x) = (x^2 + 5x + 6)(x + 5) - (x^2 + 3x - 4)(x + 7)
= (x^3 + 10x^2 + 31x + 30) - (x^3 + 10x^2 + 17x - 28) = 14x + 58
A(x) = 0 => 14x + 58 =0 => x = -58/14 = -29/7

find three consecutive integers for which 3 times the sum of the first and third integers is -342? show step by step
Answer: The integers are -58, -57, -56.
Step-by-step explanation:
The difference between two consecutive integers is 1.
If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.
Integers: x, x + 1, x + 2
The sum of the first and third is: x + x + 2
3 times the sum of the first and third is: 3(x + x + 2)
That product equals -342.
3(x + x + 2) = -342
3(2x + 2) = -342
Divide both sides by 3.
2x + 2 = -114
Subtract 2 from both sides.
2x = -116
Divide both sides by 2.
x = -58
x + 1 = -57
x + 2 = -56
The integers are -58, -57, -56.
I'm always forgetting how to do mean absolute deviation. Can someone remind me what the process is please?
Answer:
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.

A group of 5 friends went to a baseball
game and spent a total of $93.75. If the
total money spent was divided evenly, how
much did they each spend?
Answer:
They each spent 18.75.
Step-by-step explanation:
Divide 93.75 by 5.
Find the simple interest on \$5,000 at 4% interest for 3years.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 < -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 864 < 1512
2. 12 > 0
3. question 3 is wrong -2 = -2
4. -0.5 < 1
5. In the above operations, they did not effect the inequality sign because the same operation is being done to both sides, therefore the inequality sentences all remained true.
Step-by-step explanation:
1. (3)(4) < (7)(3)
(2)12 < 21(2)
(4)24 < 42(4)
(9)96 < 168(9)
= 864 < 1512
2. 3+11 > -2+3
3+ 13 > 1 + 3
-4+16 > 4-4
= 12 > 0
3. -2 = -2 (question 3 is wrong)
4. -4/-4 < 8/-4
1/-2 > -2/-2
= -0.5 < 1

If x is an integer, what is the least possible value for x that satisfies the inequality?
-5x - 12 < 33
A. -10
B. -9
C. -8
D. 9
E. 10
Answer:
C. -8
Step-by-step explanation:
We have to solve the inequality by isolating x.
-5x - 12 < 33
Add 12 to both sides.
-5x < 45
Divide both sides by -5 (remember to flip the sign when dividing by a negative).
x > -9
The least possible value for x that satisfies this inequality is -8.
Joseph said that a rhombus with side lengths of 6 meters and a height of 4 meters has the same area as a parallelogram with a base of 12 meters and a height of 2 meters. Is he correct? Critique Joseph's reasoning. help plzz
Answer:
Area(s) of both rhombus and parallelogram are equal at 24 meters squared. Therefore Joseph had the correct reasoning in regards to area(s) of both rhombus and parallelogram are equal at 24 meters squared.
Step-by-step explanation:
To equate area of the rhombus, multiply the side length and height of rhombus in meters. (6 meters×4 meters=Area of 24 m°2). Area of parallelogram = (12meters ×2 meters= 24 m°2. Area(s) of both rhombus and parallelogram are equal at 24 meters squared. therefore

Find prime factorization of 50.
1st find the factors of 50 until you only have prime numbers.

2x25=2x5x5
So the prime factorization of 50 is: 2x5^2
Answer:

Step-by-step explanation:
Length = 500
500= 5 *100
100=10^2

Rewrite using a negative exponent.
1/3^2
Answer:
1/9 or 3^-2
Step-by-step explanation:
Ignore the value of 1/3 for now and just focus on the 3^2.
Find 3^2:
3*3 = 9
Now 9 is the denominator, therefore our answer would be 1/9 once you reassemble the fraction.
Because 1/9 is our new fraction, we can use a negative exponent to create the same result. This is because the negative exponent rule tells us that a number with a negative exponent should be put to the denominator. Therefore we can then use 3^-2.
Answer:
3^-2

What is the value of the independent variable at point A on the graph?
Answer:
6
Step-by-step explanation:
The independent value refers to the x values of a graph. Point A is located at (6, 3). Therefore, the value of the independent variable is 6.
The value of the independent variable at point A on the graph is 6.
What is Independent Variable?The cause is the independent variable. Its value is unaffected by the other study variables.
In an experimental study, an independent variable is one that you change or alter to examine its effects. It is named "independent" because it is unaffected by any other study variables.
Given:
We have two quantities from the graph one is mass in grams and another is time.
as, the masses totally depends on growth of bay with time.
So, the dependent variable is Mass and independent variable is Time.
Now, the coordinates for Point A is (6, 3).
Hence, the value of point A is 6.

i have 30 coins. some of them are dimes, and some of them are quarters. in total, i have $4.05. how many of each coin do i have?
Answer: 23 dimes & 7 quarters
Step-by-step explanation:
Dimes = 10¢ = $0.10Quarters = 25¢ = $0.25Number of dimes = xNumber of quarters = yYou can create two equations:
[tex]\left \{ {{x + y = 30} \atop {0.10x + 0.25y =4.05}} \right.[/tex]
Rearrange x + y = 30:
[tex]y=30-x[/tex]
Substitute it into the x-value of the other equation & solve:
[tex]0.10x + 0.25y =0.10x + 0.25(30-x)=4.05\\0.10x+7.5-0.25x=4.05\\0.10x-0.25x=4.05-7.5\\-0.15x=-3.45\\x=\frac{-3.45}{-0.15} =23[/tex]
With the x-value, substitute it back to the original equation to find y-value:
[tex]y=30-x=30-23=7[/tex]
Therefore, there are 23 dimes & 7 quarters.
There are 23 dimes and 7 quarters.
Given that, the total number of coins=30.
How to convert dimes to dollars?To convert dimes to dollars we need to multiply the number of dimes by 0.1.
Let the number of dimes be x, and then the number of quarters will be 30-x.
Now, x×0.1+(30-x)×0.25=4.05
⇒-0.15x=-3.45
⇒x=23
30-x=7
Hence, there are 23 dimes and 7 quarters.
