What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The algebraic expression represents the phrase:
“seven more than half of a number”
As we know, expression can be defined as the combination of constants and variables with mathematical operators.
Let y be the number:
y = 7 + (1/2)x
The above equation represents the linear equation.
Thus, the expression is 7 + (1/2)x which represents the phrase “seven more than half of a number option (C) is correct.

The radius of a circle is 4 miles. What is the area of a sector bounded by a 180 arc?
Answer:
The area of sector is [tex]25.12 miles^2[/tex]
Step-by-step explanation:
Radius of circle = 4 miles
We are supposed to find the area of a sector bounded by a 180 arc
[tex]\theta = 180^{\circ}[/tex]
Area of sector =[tex]\frac{\theta}{360^{\circ}} \pi r^2[/tex]
Area of sector = [tex]\frac{180^{\circ}}{360^{\circ}} \times \frac{22}{7} \times 4^2[/tex]
Area of sector = [tex]25.12 miles^2[/tex]
Hence The area of sector is [tex]25.12 miles^2[/tex]

what is 10 1/3 x 1/4? that is, what is ten and one third times one fourth?
Answer: 31/12, or 2 7/12
Step-by-step explanation: The answer is actually very simple. All you have to do is to simplify 10 1/3 into 31/3, as 10x3+1=31. Then, you have to multiply 31/3 with 1/4. Do a simple fraction multiplication, and you get 31/12, or 2 7/12 if your teacher is asking for a mixed number. Sometimes simplifying is better

2) Find a quadratic equation that has two solutions x = 7
Give your answer without brackets.
1) You need to work this problem backwards.
x=0 and x=5 and those are the roots so the factoring must have looked something like this:
(x-0)(x-5) Then you would FOIL it:

44 is equal to 8 times a number minus 4. what is the number?
Answer:
6
Step-by-step explanation:
Let "a number" = x
44 = 8x - 4
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First add 4 to both sides:
44 (+4) = 8x - 4 (+4)
44 + 4 = 8x
48 = 8x
Isolate the variable, x. Divide 8 from both sides:
(48)/8 = (8x)/8
x = 48/8
x = 6
6 is your answer.

Evaluate 5 + 1.3 • 8.7
Step-by-step explanation:
16.31
.......................
Answer:
16.31
Step-by-step explanation:
You want to start with multiplying because of PEMDAS, so
1.3 x 8.7
so 7 x 3 = 21, and carry the two, then 7 x 1 = 7 + 2 = 9.
at the bottom you now have that it equals 9.1
so, now you start your next line and put a 0.
then, 8 x 3 = 24, of course carry the 2, and 8 x 1 = 8 + 2 = 10.
you will now have 10.40 under that
you then add 9.1 + 10.40 to get your answer of
11.31
lastly, just simply add
11.31 + 5
and you get your final answer of 16.31

The expression on the left side of an equation is shown below.
3(x+1)+9=0
If the equation has no solution, which expression can be written in the box on the other side of the equation?
3[x+4)
2[x+8)+x
4(x-3) -
03(x+1)+9x
Answer:
A. 3(x + 4)
Step-by-step explanation:
All we have to do to get the expression on the other side is to expand the bracket on the left and factorise the expression.
The equation given is:
3(x + 1) + 9 = 0
Expanding the left hand side and factorising:
3x + 3 + 9
=> 3x + 12
=> 3(x + 4)
Therefore, the expression that can be written on the other side is 3(x + 4)

Kelly rolls two number cubes 50 times. After each roll, she records whether the number on
each cube is even (E) or odd (O). Her results are shown in the graph. Based on Kelly's results,
which is the most reasonable prediction for the number of times two odd numbers will occur
when two number cubes are rolled 2,000 times?
Answer:
480
Step-by-step explanation:
First add the numbers in the table together and put the total as a denominator in a fraction then the amount of times 2 odd numbers appeared as the numerator then put another fraction with 2,000 as the denominator and divide 2,000 by the total then multiply the numerator by that answer to get the correct answer.
Hope this helped!
Using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.
What is fraction?A fraction is " a number is expressed as a quotient in which numerator is divided by denominator".
According to the question,
Kelly rolls two number cubes 50 times, each cube is even (E) or odd (O).
The graph shows frequency of two numbered cube roll. The frequency of getting EO is 14, frequency of getting OE is 8, frequency of getting EE is 16 , frequency of getting OO is 12.
Total number of frequency = 14 + 8 + 16 + 12
= 50
The fraction of getting two odd numbers when cube is rolled 50 times
= [tex]\frac{12}{50}[/tex]. →(1)
In order to find, when two number cubes are rolled 2,000 times the number of times two odd numbers will occur.
= [tex]\frac{x}{2000}[/tex]. →(2)
Equating two fraction, to get value of 'x'.
[tex]\frac{12}{50} = \frac{x}{2000}[/tex]
[tex]\frac{12*2000}{50}[/tex] = x
x = 12 × 40
x = 480.
Hence, using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

Answer:
The answer is B
STEP BY STEP EXPLANATION BOIZ:
if its an odd number four times the result = 4 x (1 + 3 + 5)
If result is even you must pay five times the result = 5(2 + 4 + 6)
So 4 x (1 + 3 + 5) x 1/2 - 5(2+4+6) x 1/2 is the answer

Answer:
The positive whole-number factors of 30 are:
1, 2, 3, 5, 6, 10, 15 and 30.
So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that
