what is x - (14x-4) + 12 = 6x + 32
Answer:
x= -16/19
Step-by-step explanation:
x−14x+4+12=6x+32
−13x+16=6x+32
16=6x+32+13x
16=19x+32
16−32=19x
−16=19x
-16/19=x

What should be done to both sides of the equation in order to solve y - 4.5 = 12.2?
Given: What should be done to both sides of the equation in order to solve y - 4.5 = 12.2?
To Find: What should be done on both side of equation.
Solution:
Step1 : Add 4.5 both sides so that +4.5 gets eliminated from LHS ,
=> y-4.5+4.5=12.2+4.5
=> y = 16.7
Hence the value of y is 16.7.
To need to solve the equation we need to add 4.5 on both sides and the value of y will be 16.7.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In other words, the equation must be constrained with some constraints.
As per the given equation,
y - 4.5 = 12.2
Add 4.5 on both sides of the equation,
y - 4.5 + 4.5 = 12.2 + 4.5
y = 16.7
Hence "To need to solve the equation we need to add 4.5 on both sides and the value of y will be 16.7".

Question 1 of 5 The Ridgeport school district collected data about class size in the district. The table shows the class sizes for five randomly selected kindergarten and seventh-grade classes. Number of students in randomly selected class Mean Mean absolute deviation Kindergarten 18, 20, 21, 19, 22 20 1.2 27, 32, 33, 33, 35 32 2 Seventh grade Based on these data, which statement is true?
sorry I couldn't fit the answer in it
Answer:
C is the correct answer
Step-by-step explanation:
Based on the data provided, the correct statement is:
A. The average size of a seventh-grade class is larger and varies more than that of a kindergarten class.
Here's the explanation:
1. Average class size:
The mean (average) class size for kindergarten is given as 20, while for the seventh grade, it is given as 32. Since 32 is greater than 20, we can conclude that the average size of a seventh-grade class is larger than that of a kindergarten class.
2. Variation in class sizes:
The mean absolute deviation (MAD) is provided as 1.2 for kindergarten and 2 for the seventh grade. The MAD measures the average amount by which each data point differs from the mean. A higher MAD indicates greater variability. In this case, the MAD for the seventh grade (2) is higher than that for kindergarten (1.2), indicating that the class sizes in the seventh grade vary more than those in kindergarten.
Therefore, the average size of a seventh-grade class is larger and varies more than that of a kindergarten class.

A shipment of 5 boxes of toys weighed
34.53 pounds. Each box measures the same
weight, so what's the weight of 1 box?
Answer:
Each box weighs 6.906 pounds.
Step-by-step explanation:
We know the total weight of the boxes. We also know how many boxes we have. To find the weight of one box, we want to divide the total weight by the total number of boxes.
34.53 / 5
= 6.906
Each box weighs 6.906 pounds.

The Leungs sold a valuable painting for $55,000. This price is $1,000
more than twice the amount they originally paid for it. How much
did they originally pay?
A. $25,000 B. $27,000 C. $27,500 D. $28,000
Answer:
B. $27,000
Step-by-step explanation:
So 55,000 = 2x + 1,000
Simply for x
55,000 = 2x + 1,000
54,000 = 2x
x = 27,000

In the standard (x, y) coordinate plane which equation represents a line through the point (6, 1) and perpendicular to the line with the equation =3/2 + 1?
A.) = −3/2 − 8
B. ) = −2/3 − 3
C.) = −2/3 + 1
D.) = −2/3 + 5
E.) = −3/2 + 10
Answer:
d. -2/3x+5
Step-by-step explanation:
Because the line is perpendicular, the slope must be the inverse of the original slope. The inverse of 3/2 is -2/3. To find the b value, you plug (6,1) into the equation y=-2/3x+b
1=-2/3(6)+b
1=-4+b
5=b
The final equation is y=-2/3x+5

JK and LM are perpendicular diameters of a circle. They are each 12 inches long. What is the approximate length of chord LK? With Explanation Please
Answer:
8.5 inches
Step-by-step explanation:
Let the center of the circle = C
Now CK = CL = 6
Using Pythagoras theorem
LK^2 = CL^2 + CK^2
= 6^2 +6^2
= 36 + 36
= 72
LK = 72 ^1/2
= ( 36*2)^1/2
= 6(2)^1/2
= 8.5 inches

Answer:
1824 in.
Step-by-step explanation:
First find the area of the two shapes you split that are the rectangle and triangle:
Rectangle Area:
48 * 32 = 1536
Area- 1536 in.
Triangle Area:
48 * 12 * 1/2
or
48 * 12 divided by 2
= 288 in.
Now add the two areas up:
1536 + 288 = 1824 in.
Answer:
1824
Step-by-step explanation:
I assume you want to find the area of the shape. So in order to find the area of the triangle it is height times base than divide it by 2 which looks like this
(12*48)/2 which equals 576
than to find the area of the rectangle it is height times width which is
48*32 which equals 1536
add them together and you get 1824

i need more helppppppppp, i have to find the area of this circle
Answer:
You need to find the radius first,
Half of 23 is = 11.5
Formula you must remember when finding area of circle is:
πr^2
(pie (3.14 or 22/7) x radius squared)
Our pie is 3.14 because they said to use it in this particular question.
3.14 x 11.5^2 (remember we are making our radius squared) <--- Before
Let's evaluate first:
3.14 x 132.25 <--- After evaluating
So, 3.14 x 132.25 = 415.265 <----- your answer
