Answer:
x = 22
Step-by-step explanation:
rearange the equation to 25-3=x. 25-3 = 22, therefore x = 22
Answer: X =22
Step-by-step explanation: Switch sides x + 3= 25 then subtract 3 from both sides x + 3 - 3= 25-3 then simplify and you get X=22
which expression represents purely real numbers and which expression represents non-real complex number?
Incomplete question. However, I provided some explanation about non-real complex numbers.
Explanation:
In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.
For example, the numbers 3i, 3 + 5i, 3i/4 are non-real numbers because of the addition of an imaginary part which is denoted by 'i'.
While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.

Rita and Lumiere are solving a problem about driving to Scream N Barf theme park... They know that the theme park is 30 miles away and that they will drive an average of 15 miles per hour. They need to write an equation and solve it to find out how long it will take to get there.
Rita says they should the formula `d=rt`, where `d` is the distance traveled in miles, `r` is the rate of speed in miles per hour, and `t` is the time in hours.
Lumiere says they should use the equation `t=\frac{d}{r}` instead. Who is right? Explain.

Answer:
Lumiere
Step-by-step explanation:
Rita is correct that the relation between distance, speed, and time is given by ...
d = rt
Since they want to find the time, they would have to solve this equation for t, which would give ...

Find the discriminant of the equation and give the number and type of solutions of the equation 4x^2+2x-5=0
Please help fast!!
Answer:
The answer is 84.
Step-by-step explanation:
The given equation is
4x*2 + 2x -5 = 0
Here a= 4, b= 2, c= -5
Since Discriminant= b*2 -4ac
Putting values
Discriminant= (2)*2 - 4(4)(-5)
= 4 + 80
= 84
Since our Discriminant(84) is >0 and is not a perfect square so the roots of the given equation are unequal and irrational(real).

show me a Graph x=−4.
Answer:
The graph of line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,
Step-by-step explanation:
Given the line
x=−4
The given line x=-4 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-4 is undefined.
As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
The graph of the line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,

Two-Way Frequency Tables Please Help.
Answer:
17%
Step-by-step explanation:
Percentage of full time employees who ride bus to and fro from work?
Since the table as been arranged as a two way frequency table., we only need to find the value at the intersection of the two Given conditions ;
Horizontally, the type of ride = bus
Vertically, the type of employee = full-time
Hence, full time employees who take bus to and fro = 0.17
As a percentage =, (0.17 * 100) = 17%

Sissy wants to enlarge a picture of a constellation so that she can put it on the wall in her daughter’s room. What will be the area of the enlarged picture on the wall?
24 in.2
108 in.2
224 in.2
486 in.2
Answer: 486 in
Just did this on edge
The enlargement transformation applied to the rectangular figure gives
a rectangle that is enlarged and similar to the figure.
Correct response:
The area of the enlarged picture is 486 in.²The given dimensions of the picture are;
Height, [tex]\overline{MN}[/tex] = 6 in.
Width, [tex]\overline{LP}[/tex] = 4 in.
The length of QL' = 12 + 42 = 54
By similar triangles, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{ \dfrac{\overline{QL'}}{\overline{QL}}}[/tex]
Which gives;
[tex]\dfrac{\overline{L'P'}}{6} = \mathbf{ \dfrac{54}{12}}[/tex]
[tex]\overline{L'P'} = \dfrac{54 }{12} \times 6 = \mathbf{27}[/tex]
Given that an enlargement gives similar figures, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{\dfrac{\overline{L'M'}}{\overline{LM}}} = Scale \, factor \ of \ the \ enlargement[/tex]
Therefore;
[tex]\dfrac{27}{6} = \dfrac{\overline{L'M'}}{4}[/tex]
Which gives;
[tex]\overline{L'M'} = \dfrac{27}{6} \times 4 = \mathbf{ 18}[/tex]
The area of the enlarged picture is, A = [tex]\overline{L'M'}[/tex] × [tex]\overline{L'P'}[/tex]
Which gives;
A = 27 × 18 = 486
The area of the enlarged picture on the wall is A = 486 in.²

Step-by-step explanation:
Answer:
10.5 or 21/2
Step-by-step explanation:
The question is asking how many 2/7 are in 3. So let make 3 a equivalent fraction that has 7 as it denomanater. 7/7 is 1, 14/7 is 2, so 21/7 is 3. Now let divide 21/7 by 2/7. flip 2/7 around to 7/2 then multiply by 21/7 which equals
[tex]\frac{147}{14}[/tex] which equals 10.5 or 21/2.

Chanelle deposits $7,500 into the bank. She does not withdraw or deposit money for 6 years. She earns 6% interest during that time. a. How much interest will she have earned at the end of 6 years? She will earn $2,700 interest b. What will the balance be when she is finally able to withdraw her money?
Answer: a. $2700
b. $10200
Step-by-step explanation:
a. The interest she would have earned at the end of the 6 years can be gotten using the formula
= PRT/100
= $7500 × 6% × 6
= $7500 × 6/100 × 6
= $7500 × 0.06 × 6
= $2700
b. Her balance when she wants to withdraw the money would be:
= $7500 + $2700
= $10200
