Latisha has $40 in her checking account. She makes a withdrawal of $20 and then writes a check for $40. Then she deposits $30. Use the number line and complete the equation to find her final balance.
The final balance that will be in the account of Latisha is $10.
What is a checking account?A checking account simply means the account that makes use of a check. It is usually used by business owners.
From the information, Latisha has $40 in her checking account, she makes a withdrawal of $20 and then writes a check for $40 and then she deposits $30.
The appropriate operations to find the balance will be:
= 40 - 20 - 40 + 30
= 10
She will have $10 left. Note that a withdrawal is subtraction.

When 12 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.
When 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2
Consider the number as x
Square of the number = [tex]x^{2}[/tex]
12 subtracted from the square of a number = [tex]x^{2} -12[/tex]
4 times the number = 4x
Then the equation will be [tex]x^{2} -12=4x[/tex]
Rearrange the terms and it will become a quadratic equation
[tex]x^{2} -4x-12=0[/tex]
Split the middle term and solve the equation
[tex]x^{2} +2x-6x-12=0[/tex]
Take common terms
x(x+2)-6(x+2) = 0
Take common term outside
(x-6)(x+2) = 0
Therefore
x = 6, -2
The negative solution is -2
Hence, when 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2

Step-by-step explanation:
In the diagram below, isosceles triangle ABC is drawn with AB is congruent AC and side BC extended through point D. If
m/ACB=2x+16 and m angle ACD=5x+24, find the measure of angle A.
Answer:
32°
Step-by-step explanation:
Angle A + angle B = angle ACD
Since it is an isosceles triangle angle a = angel b
2(2x + 16) = 5x +24 distribute the 2
4x + 32 = 5x + 24 Subtract 4x from both sides
32 = x + 24 Subtract 24 from both sides
8 = x
Now plug in 8 for x in 2x + 16
2(8) + 16
16+ 16 = 32
us the data set to choose the two measures that are equivlent 4, 5, 6, 7, 8
The mean and median of the data are equivalent and the value is 6.
The mean (average) of a data set can be calculated by adding up all the numbers in the collection and dividing by the total number of values in the set.
When a data set is sorted from least to greatest, the median is the middle. The value that pops up most frequently in a data set is its mode.Between the lowest and highest value is the range. You subtract the lowest value from the greatest value to calculate it.The exact midpoint between the lowest and highest values in a set of data is the midway value. Finding the middle requires adding the smallest and greatest values together, then dividing the result by two.Let us find the mean of the data set :
mean = (4 + 5 + 6 + 7 + 8) ÷ 5 = 30÷ 5 = 6
Median = 6 middle value.
Therefore the mean and median are equivalent.

2x+5+7x = 8x-11 solve for x
Answer:
x
Step-by-step explanation:
2x + 5 + 7x = 8x -11 Combine like terms
9x + 5 = 8x -11 Subtract 8x from both sides of the equation
x + 5 = -11 Subtract 5 from both sides of the equation.
x= -16
Answer: -16
Step-by-step explanation:
2x+5+7x = 8x-11 simplifies into 9x+5 = 8x -11.
Move 8x to the other side - put like terms together : 9x-8x+5 = -11
Which is simplified into x+5 = -11
Move 5 to the other side to isolate x: x = -11 -5
Combine -11 and -5
x = -16

0.68 is a rational number and the reason is because:
It is a decimal that terminatesWhy is 0.68 a rational number?0.68 can be regarded as a rational number because it is a finite number that is also a fraction of two whole integers. In this case, the integers are 68 and 10. Another feature by which rational numbers are known is the fact that they are repeating in nature.
However, it is important to note that the decimal here is terminating in nature because it has a finite number of zeros behind the number 8. So, the reason for selecting 0.68 as a rational number is that it terminates.

Answer: I think the answer is $1.21
Step-by-step explanation: Instead of 3 pairs it says 3 dozen. A dozen is 12.
3 x 12 = 36
Then you should do 43.56 / 36
For one pair of gloves it should be $1.21
The contractor got $14.52 because he did a dozen (12) divided by 43.56.
