Answer:

x= -8

Step-by-step explanation:

This can be done several ways:

The easiest is to factor out 12 from both sides so:

12(9-6x) = 12 (58-1)

12(9-6x) = 12 (57)

Cancel 12 from both sides so:

9-6x = 57, then...

-6x = 48

x= -8

Xavier can work no more than 40 hours in a week. He has already worked 24 hours this week. What is the maximum number of 8-hour

MrRissso [65]

Answer:

He can work a maximum of 2 8-hour days for the remainder of the week

Step-by-step explanation:

Firstly, from the question, we are made to know that the maximum work hours is 40 hours.

Now, we know that he has already worked 24 hours this week, the number of hours remains to work will be 40-24 = 16 hours

Now, given that his working hour is 8-hours per day, we want to know the number of days he has to work for the remainder of the week

Mathematically, that would be 16 hours divided by 8-hours days

That is 16/8 = 2

Answer:

see below

Step-by-step explanation:

27.

We can use ratios to solve

152 dollars 532 dollars

---------------- = ----------------

4 days x days

Using cross products

152x = 4*532

152x =2128

Divide each side by 152

152x/152 = 2128/152

x =14

14 days

29.

1 inch 2/3 inches

------------ = ----------------

6.5 ft x ft

Using cross products

1x = 2/3 * 6.5

x = 4.333333

c = 4 1/3 ft

Select the correct responses in the table. The relationship between two numbers is described below, where x represents the first

Answer:

x² = y + 16
4y - 1 = 7x
(5, 9)

Step-by-step explanation:

Writing equations from words is mostly a matter of understanding what the English words mean.

If the first number is x, then the square of the first number is x². That is said to be equal to the sum of the second number (y) and 16:

x² = y + 16 . . . . the first equation

The wording "the difference of A and B" is usually intended to be interpreted to mean A-B. Here, we have the difference of 4 times the second number (4y) and 1, so ...

4y -1

This is equal to the first number (x) multiplied by 7, so ...

4y -1 = 7x . . . . the second equation

These can be solved a variety of ways. When no method is specified, I like to use a graphing calculator. It shows the only integer solution for this pair of equations is ...

(x, y) = (5, 9)
