4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5

Morgarella [4.7K]

Hey there! Let's figure this question out for you!

A math conjugate, is formed by changing the sign between two terms in a binomial.

An example would be:

4+7x would become 4 - 7x.


I hope this helps!

A local theatre sells out for their show. They sell all 500 tickets for a total purse of $8,040.00. The tickets were priced at $
Sever21 [200]

Answer:

number of children ticket sold = 70

number of adult ticket sold = 70 × 3 = 210

number of student ticket sold = 500 - 4(70) = 500 - 280 = 220

Deshaun works as a tutor for 15 an hour and as a waiter for an hour. This month, he worked a combined total of hours at his two
Valentin [98]

Answer:

Total Earning = 15b + M(N - b)

where:

b is the total hours worked as a tutor

M is the amount earned by Deshaun per hour as a waiter

N is the total number of possible hours Deshaun can work in a month

Step-by-step explanation:

Let the number of hours Deshaun works daily as a waiter be w

and the time worked daily as a tutor be t

Deshaun earns $15 per hour as tutor hence daily earnings on tutoring = 15t

Let Deshaun earn $M per hour as waiter, hence daily earning as a waiter is Mw

The total possible hours Deshaun can work in a month is dependent on conditions not specified.

However, assuming 24 working days (6 days weekly for 4 weeks) in a month with maximum approved work hours of 12 hours daily

total hours Deshaun can work will equal 24 x 12 = 288hrs

Note: This 288hrs is an estimate and can change based on applicable hours of work daily and number of working days in a month; it can also be represented as N

If b is the total hours Deshaun worked as a tutor this month,

the hours Deshaun can work as a waiter in a month is equal to 288 - b

Hence in a month, Deshaun will earn 15b as a tutor and M(288-b) as a waiter or optionally M(N - b)

Therefore combined dollar amount earned in a month is

Total Earning = 15b + M(N - b)

Factor the expression below.
Mrac [35]

Answer:

A. (x - 5)(x - 5)

Step-by-step explanation:

We will do this the old fashioned way...just plain old factoring.  

This polynomial is of the form

y=ax^2+bx+c

The product of a and c have to add up to equal the "middle" term, -10.  

a = 1, b = -10, c = 25

a * c = 1 * 25 = 25

Now we need the factors of 25 to find the combination of factors that will result in a -10.  The factors of 25 are: 1, 25 and 5, 5

5 and 5 add up to be 10, but since we need a -10, we will use -5 and -5.  The product of -5 * -5 = 25, so we are not messing anything up by using the negative 5.

Putting them in order in standard form we have

x^2-5x-5x+25

Factor by grouping:

(x^2-5x)-(5x+25)

There is an x common to both terms in the first set of parenthesis, so we will factor that out; there is a 5 common to both terms in the second set of parenthesis, so we will factor that out:

x(x - 5) - 5(x - 5)

NOW what's common in both terms is the (x - 5) so we factor THAT out, and what's left gets grouped together:

(x - 5)(x - 5)
