5) 9x + 2 =119

9x +2 - 2 = 119 - 2

9x= 117

9x/9 = 117/9

x=13

6) 12x - 8 + 104 = 180

12x + 96 = 180

12x + 96 -96 = 180 - 96

12x = 84

12x/12 = 84/12

x=7

4x=44

4x/4=44/4

x=11

13(11)-19+17y+5=180

143-19+17y+5=180

129+17y=180

129-129+17y=180-129

17y=51

17y/17=51/17

y=3

10) 8y+17=6x-7

3x-29+6x-7=180

9x-36+36=180+36

9x=216

9x/9=216/9

x=24

8y+17= 6(24)-7

8y+17= 144-7

8y+17= 137

8y+17-17=137-17

8y=120

8y/8=120/8

y=15

Answer:

Equation:

y = x+1

Distance Equation:

sqrt[x^2 + y^2] = 5

===========================

Substitue for "y" and solve for "x":

sqrt[x^2 + (x+1)^2] = 5

x^2 + x^2 + 2x + 1 = 25

2x^2 + 2x -24 = 0

x^2 + x - 12 = 0

Factor:

(x+4)(x-3) = 0

x = 3 miles (eastbound distance)

x+1 = 4 miles (southbound distance)

Step-by-step explanation:

64.50=5x+58.50

64.50=5(1)+58.50

64.50=63.50 CORRECT

It can't be 2 because it will be over 64.50

5(2)+58.50

10+58.50

68.50 WRONG

Avery can use up to 1.2 gigabytes of data while staying within her budget of $64.50 per month.

The equation to determine the number of gigabytes of data Avery can use while staying within her budget can be written as:

$58.50 + $5x = $64.50

Where:

$58.50 represents the flat cost per month

$5x represents the cost based on the number of gigabytes used (x gigabytes)

$64.50 is the total budget she wants to stay within

To solve for x, we can subtract $58.50 from both sides of the equation:

$5x = $6.00

Then, divide both sides by $5:

x = 1.2

So, Avery can use up to 1.2 gigabytes of data while staying within her budget of $64.50 per month.

#SPJ3

Answer:

Let's make each of these workers' salaries a variable. For our purposes:

x = the annual salary of the warehouse manager

y = the annual salary of the office manager

z = the annual salary of the truck driver

*Since all of our variables describe an "annual salary" in dollars, we do not have to perform unit conversions.

From the sentence, "The sum of the annual salaries of the warehouse manager and office manager is $75000," we can derive the equation:

warehouse manager + office manager = 75000

x + y = 75000

From this sentence, "The sum of the  annual salary of the office manager and the truck driver is $75000," we get:

office manager + truck driver = 75000

y + z = 75000

Finally, since "The annual salaries of the warehouse  manager and the truck driver total $70000," we know that:

warehouse manager + truck driver = 70000

x + z = 70000

From the above equations, we can create a system of equations to reach the solution.

x + y = 75000

y + z = 75000

x + z = 70000

Using the substitution method and basic algebra, this question is easy! Let's solve for x, the warehouse manager's salary, first:

x + z = 70000

z = 70000 - x

y + z = 75000

y + (70000 - x) = 75000

y + 70000 - x = 75000

y - x = 5000

y = 5000 + x

x + y = 75000

x + (5000 + x) = 75000

x + x + 5000 = 75000

2x + 5000 = 75000

2x = 70000

x = $35000 = warehouse manager's annual salary

Now that we have solved for one of the variables, we can substitute our answer back in to get a quicker result:

x + z = 70000

(35000) + z = 70000

z = 35000$ = truck driver's annual salary

y + z = 75000

y + (35000) = 75000

y = $40000 = office manager's salary

So, our answers would be that:

The warehouse manager's annual salary is $35000.

The office manager's annual salary is $40000.

The truck driver's annual salary is $35000.

Answer:

(- 1, 3 )

Step-by-step explanation:

y = - x + 2 → (1)

3x - y = - 6 → (2)

Substitute y = - x + 2 into (2)

3x - (- x + 2) = - 6 ← distribute parenthesis and simplify left side

3x + x - 2 = - 6

4x - 2 = - 6 ( add 2 to both sides )

4x = - 4 ( divide both sides by 4 )

x = - 1

Substitute x = - 1 into (1)

y = - (- 1) + 2 = 1 + 2 = 3

solution is (- 1, 3 )

12x62=$744 for 62 packs of Expo markers

Answer:

Step-by-step explanation:

The maximum area of the figure is 4.5 square units.

Given,

Write an equation for area A of the figure.

Then determine the maximum possible area of the figure.

It is given by:

Area = 1/2 x base x height

When we maximize an area we must differentiate the area.

If A is the area.

A' = 0

We have,

From the figure:

Base = 6 - b

Height = b

Now,

Area = 1/2 x base x height
Area = 1/2 x ( 6 - b ) x b

A = (6b - b²) / 2

A = 3b - b²/2

When we maximize an area we must differentiate the area and thus,

A' = 0

So,

A' = 3 - 2b/2

0 = 3 - b

b = 3

Now,

A = 3b - b²/2

A = 3 x 3 - 3²/2

A = 9 - 9/2

A = (18 - 9) / 2

A = 9/2

A = 4.5 square units.

Thus the maximum area of the figure is 4.5 square units.

Answer:

±√5 are the solutions to x^2=5

Step-by-step explanation:

Write out x^2=5.  Now enclose each of the two sides in parentheses.  Apply the exponent (1/2) to both sides:

(x^2)^(1/2) = (5)^(1/2)

The left side simplifies to x and the right side to ±√5.

So ±√5 are the solutions to x^2=5.
