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

A race is 25 miles long. There is a water station every 1 1/4 miles along the race route. How many water stations are needed for

Vikentia [17]

Answer:

Step-by-step explanation:

21 water stations

Step-by-step explanation:

From the question, we are informed that a marathon is 26.2 miles long and that there is a water station every 1 1/4miles along the race route and at the finish line.

To get the number of water stations that are needed for this marathon, we divide 26.2 miles by 1 1/4miles. This will be:

= 26.2miles/1 1/4 miles

= 26.2 miles/1.25 miles

= 20.96

= 21 water stations

What is the value for y in the following equation when x = -10?

nadezda [96]

Answer:

B.-38

Step-by-step explanation:

2x - 18 = y ...(1)

x = -10 (Given)

Now,

Put the value of x in equation (1) we get,

2(-10) - 18 = y

-20 - 18 = y

-38 = y

y = -38

Thus, the value of y is -38

What is the slope of the line graphed below (3,5) (0,-1)

Leona [35]

You can just do rise over run to find the slope or use the slope equation which is
$y = y1 - y2 \div x1 - x2$
3=x1
0=x2
5=y1
-1=y2
input those and you can get the slope graphed.

Make b the subject a=4b+2/3-b

Rasek [7]

Answer:

b = $\frac{3a-2}{9}$

Step-by-step explanation:

Given

a = 4b + $\frac{2}{3}$ - b, that is

a = 3b + $\frac{2}{3}$

Multiply through by 3 to clear the fraction

3a = 9b + 2 ( subtract 2 from both sides )

3a - 2 = 9b ( divide both sides by 9 )

$\frac{3a-2}{9}$ = b

Savings = $150.00

Electric = 156.33

Gas = 9.38

Water = 98.42

TV = 52.54

Total bills = 466.67

Remaining = $ 780.59
