10 6v + 3 = 30
Please answer!!! 3x+4=9x+3
Answer:
x = 1/6
Step-by-step explanation:
"solve for x" would be better and clearer than "please answer."
We start the solution by subtracing 3x from both sides, obtaining
4 = 6x + 3
and then isolate the 3x term by subtracting 3 rom both sides:
6x = 1
Finally we divide both sides of this result by 6, obtaining
x = 1/6 This is the "answer" to the problem "solve 3x + 4 = 9x + 3 for x."
Sarah makes $16 and hour. She works 44 hours this week. Optional
deductions are $50 for health insurance and $100 for child care. Federal
taxes are 8% State taxes are 7% and FICA is 7.65%. What is Sarah's NET
pay?
Answer:
$437.74
Step-by-step explanation:
16 x 44 = 704 -150=554 x 0.08= 554-44.32= 509.68 x 0.07= 509.68 - 35.6776 = 474 x 0.0765 = 474 - 36.261 = 437.74
Answer:
$ 394.54
Step-by-step explanation:
Sarah makes $16 and hour. She works 44 hours this week.
Optional deductions are
- $50 for health insurance and
- $100 for child care.
- Federal taxes are 8%
- State taxes are 7% and
- FICA is 7.65%.
What is Sarah's NET pay?
salary for a week: $16 x 44 = $704
deductions:
- health insurance and - $50
- child care. - $100
- Federal taxes are 8% = 0.08 (704) = - $53.32
- State taxes are 7% 0.07 (704) = - $49.28
- FICA is 7.65% = 0.0765 (704) = -$53.86

Solve the following equation for a. 5b + 6a – 7 = 2b + 9a
Answer:
[tex]a=\dfrac{3b-7}{3}[/tex]
Step-by-step explanation:
Given that,
The given equation is :
5b + 6a – 7 = 2b + 9a
We need to solve the above equation for a. Taking he terms having a and b in LHS and constants in RHS.
5b+6a-2b-9a=7
taking like terms together
(6a-9a)+(5b-2b)=7
-3a+3b=7
Subtracting both sides by 3b. So,
-3a+3b-3b=7-3b
-3a=7-3b
Dioviding both sides by (-3). So,
[tex]a=\dfrac{7-3b}{-3}\\\\a=\dfrac{3b-7}{3}[/tex]
Hence, the value of a is [tex]a=\dfrac{3b-7}{3}[/tex].
Answer:
[tex]a = \frac{3b-7}{3}[/tex]

Data will be collected on the following variables. Which variable can be considered discrete? A. The height of a person B . The weight of a person C. The length of a person’s arm span D The time it takes for a person to solve a puzzle E The number of books a person finished reading last month
Answer: E: The number of books a person finished reading last month
Step-by-step explanation:
First, a discrete variable is a variable that only can take some given values in a set, the discrete variables are usually not dense, and a continuous variable is a variable that can take any value in a range (where the accepted values are dense).
So, for example, the set of the natural numbers is discrete, and the set of the real numbers can represent a continuous variable.
Here the only option that is really discrete will be the number of books that a person finished reading last month because here only positive whole numbers are accepted (you can not finish a 0.454 of a book)
The other options are continuous because all are classical measures.
For example, the weight of a person can jump between:
75.6kg and 75.7kg.
So you could think that this is discrete because the values between 75.6kg and 75.7g are not shown with our measuring device, but those will be added in the error of the measure because the weights between 75.6kg and 75.7kg are actually possible, so they must be accepted.
Option E is right.
A. The height of a person. Height is a continuous variable.
B . The weight of a person. Weight is a continuous variable.
C. The length of a person’s arm span. Length is a continuous variable.
D. The time it takes for a person to solve a puzzle. Time is a continuous variable.
E. The number of books a person finished reading last month. The number of books is discrete variable.
