Answer:

half the full amount of money he will earn in one full month

Step-by-step explanation:

The required algebraic expression for Alex's salary annually is 24x.

Given that,
Alex is paid semimonthly. His annual salary is y dollars.

To determine his semimonthly salary algebraically.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the salary Alex for semi-month be x,
Salary for a month would be = 2x
Now, his salary for the year is equal to 12 * 2x
Now,
accoding to the question,
y = 12*2x
y = 24x

Thus, the required algebraic expression for Alex's salary annually is 24x.

Answer:

Maybe  -3

Step-by-step explanation:

I am not 100% sure but it is better than nothing,

since 3+3=6 I think after 3 is 6, and after 6 is 9. I think that because the more right the line goes you add  3 to every move. So therefore, 3-3=0, and 0-3= -3

Hope this helps. Also, I hope I gave you the correct answer.

Answer:

x=6

Step-by-step explanation:

Because they are vertical angles, they are equal to one another, so the equation you have to set up would Be 5x=30 and you divide both sides by 5 and yopu get x=6 :)

Answer:

x= 100 degrees

Because the angles are vertical

Step-by-step explanation:

Answer:

Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15  minutes before the bell rings.

Step-by-step explanation:

Total distance from home to School [tex]= 4[/tex] km

Distance travelled by Jose in first [tex]30[/tex] minutes is equal to

[tex]\frac{30}{60} * 5\\= 2.5[/tex]

Distance to travel in next [tex]15[/tex] minutes is equal to

[tex]4 -2.5 = 1.5[/tex] Km

Required speed

[tex]\frac{1.5}{\frac{15}{16} } \\= 1.5 * 4\\= 6[/tex]

Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15  minutes before the bell rings.

Answer:

See the attachment for what goes on your X diagram.

Rewrite: x² -7x +4x -28

Grouping: (x² -7x) +(4x -28) = x(x -7) +4(x -7) = (x +4)(x -7)

Step-by-step explanation:

The given quadratic is ...

... x² -3x -28 . . . . . a=1, b=-3, c=-28

a) The value at the top of the X diagram is the product a·c = 1·(-28) = -28.

The value at the bottom of the X diagram is the coefficient b = -3.

The values on the sides of the diagram are the factors of -28 that add up to make -3. These are -7 and 4. That is, ...

(-7)·(4) = -28

(-7)+(4) = -3

b) Since the two values on the sides of the diagram add up to give "b", the value of "b" in the equation can be rewritten as the sum of these two numbers. Doing that, we have ...

... x² -3x -28

... = x² +(-7+4)x -28

... = x² -7x +4x -28 . . . . . . order does not matter. It could also be x² +4x -7x -28

c) We can group pairs of terms in the rewritten expression and factor each pair.

... = (x² -7x) +(4x -28) . . . . . first pair has a common factor of x; second pair, 4

... = x(x -7) +4(x -7) . . . . . . . these terms now have a common factor: (x -7)

... = (x +4)(x -7) . . . . . . . . . . the complete factorization of x² -3x -28

Comment on extended application

When a ≠ 1, there are a couple of additional steps. Effectively, you reduce the fractions ax/p and ax/q to a'x/p' and a''x/q'', then rewrite those as the factors (a'x+p')(a''x+q'') where the ' and '' numbers are after reducing the fractions. (The numbers may be the same as the original if the fraction cannot be reduced.) As a check, a'·a'' = a, and p'·q'' = c.
