Answer:

Step-by-step explanation:

5x-4+7x-8=180

12x-12=180

12x=192

x = 16

5(16)-4= 80-4= 76 degrees

7(16)-8= 112-8= 104 degrees

9y  +  5 = 104

9y = 99

y = 11

9(11) + 5 = 99 + 5 = 104

Answer:

Domain: (-3, 1]

Range: [-4, 0)

Step-by-step explanation:

Domain is all the x-values that can be plugged into the graph.

Range is all y-values that are outputted from inputting x.

We can see that our x-values span from -3 to 1. Since -3 is open dot, it is not included. Brackets signify inclusion.

(-3, 1]

We can see that our y-values span from -4 to 0. Since when x = -3 is open dot, the output y = 0 is also not included.

[-4, 0)

You don't multiply liters of gasoline by distance.

They are directly proportional - the more gasoline you have the longer is the dictance you can go.

So it's cross multiply.

Another examlpe:

you are paid by hour for your work. The more hours you have worked, the more you are paid:

hours      payment

2 h            $36

5 h             x    

[tex]x=\dfrac{5\cdot36}2=90[/tex]

You would multiply 10•70 if they were inversely poportional values

For example:

1. speed and time of ride by given distance {the greater the speed the less time you need for a ride}

speed          time

10 m/s          75 s

 8 m/s           x

[tex]x=\dfrac{10\cdot75}{8}=93.75\,s[/tex]

Answer:

5 x + 2

Step-by-step explanation:

Answer:

y = (-1/5)x + 2

Step-by-step explanation:

A line perpendicular to y = 5x + 2 would have a flipped opposite slope. Note the slope in the slope-intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Flip the slope:

y = 5x + 2

y = (-1/5)x + 2

y = (-1/5)x + 2 is your answer.

Answer:

b = (F - g)/2M

Step-by-step explanation:

2Mb = F - g

Divide each side by 2M

2Mb/2M = (F - g)/2M

b = (F - g)/2M

Answer: Answer in steps

Step-by-step explanation:

2Mb =f-g    Divide both sides by 2M

b= [tex]\frac{f}{2M} - \frac{g}{2M}[/tex]

Answer:

$328.13

Step-by-step explanation:

First, find the amount of time she works every day.

Between 8:45 and 5:15, there are 8.5 hours.

Subtract 1 for her lunch break, so there are 7.5 hours worked every day

Then, calculate how much she gets every day:

7.5(8.75)

= $65.625

Multiply this by 5 to find her pay for the week:

65.625(5)

= $328.13 is her total pay for the week

The total pay for the week will be $318.75.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Amanda Roberts works a Monday through Friday work week at a rate of $8.75 per hour. She takes a 1- hour lunch break. If she clocks in each day at 8:45 am and leaves at 5:15 pm.

The number of hours from 8:45 am to 5:15 pm will be 8.5 hours.

And the number of working days will be 5.

Then the total pay for the week will be

⇒ $8.75 x 5 x (8.5 - 1)

⇒ $8.75 x 5 x 7.5

⇒ $318.75

The total pay for the week will be $318.75.

Answer:

x  = 3√3 - 3

x  = -3√3 - 3

Step-by-step explanation:

(3+x)² + 9 = 36

(x + 3)² + 9 - 9 = 36 - 9

(x + 3)² = 27

x + 3 = 3√3

x + 3 = -3√3

therefore,

x  = 3√3 - 3

x  = -3√3 - 3

A multiple is a number that can be divided by that number with no remainder. For example, multiples of 5 are 5, 10, 15, and 20.

A multiple of 12 is basically 12 × (number of multiple), for example, if you want the second multiple of 12, you would multiply 2 by 12.

So multiply 12 by 1, 2, 3, 4, and 5.

12×1=12

12×2=24

12×3=36

12×4=48

12×5=60

The first five multiples of 12 are 12, 24, 36, 48, and 60.

Answer:

y=4 , x= 12

Step-by-step explanation:

This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.

x + y = 16

8 + y = x

Now you know that x = 8 + y, so replace it in the opposing equation.

8 + y + y = 16 (simplfy)

8 + 2y = 16  (subtract  8 from each side)

2y = 8 (divide each side by 2)

y = 4

plug into other formula

8 + 4 = x

x =12

Answer:

y=4 , x= 12

Step-by-step explanation:

x + y = 16

8 + y = x

8 + y + y = 16 (simplfy)

8 + 2y = 16  (subtract  8 from each side)

2y = 8 (divide each side by 2)

y = 4

8 + 4 = x

x =12

Shown work is on the image below.

Answer:

Step-by-step explanation:

1.6(15x + 25)= -6x -5

Multiply the terms

That's

24x + 40 = - 6x - 5

Add 6x to both sides

24x + 6x + 40 = 6x - 6x - 5

30x + 40 = - 5

Subtract 40 from both sides

That's

30x + 40 - 40 = - 5 - 40

30x = - 45

Divide both sides by 30

We have the final answer as

Answer:

Bill's exchange rate was $1 to £1.62

Gwyll's exchange rate was $1 to £1.56

Step-by-step explanation:

Given

Bill changed £450 into $729

Gwyll changes £500 into $780

Required

Determine their exchange rates

Exchange rate is calculated by dividing the currencies against one another.

Given that they both changed from pound to dollar, the exchange rate is calculated as thus;

[tex]Rate = \frac{Amount\ in\ pound}{Amount\ in\ dollar}[/tex]

Calculating Bill's Exchange Rate

[tex]Rate = \frac{\£729}{\$450}[/tex]

[tex]Rate = \frac{\£1.62}{\$1}[/tex]

Represent as a ratio

[tex]Rate = \£1.62:\$1[/tex]

Hence, Bill's exchange rate was $1 to £1.62

Calculating Gwyll's Exchange Rate, using the same formula and steps

[tex]Rate = \frac{\£780}{\$500}[/tex]

[tex]Rate = \frac{\£1.56}{\$1}[/tex]

Represent as a ratio

[tex]Rate = \£1.56:\$1[/tex]

Hence, Gwyll's exchange rate was $1 to £1.56

Answer:

Answer:

The difference between the two weekly salaries is $122

Step-by-step explanation:

One job pays $64,600 per year. Since there are 52 weeks in a year, the weekly salary for this job is the quotient: $64600/52 = $1242.31 which rounded to the nearest dollar gives: $1242 per week

The other job pays $1120 per week. Therefore the difference in weekly salary for the two is:

$1242 - $1120 = $122

Answer:

The total resulting gallons of water is 4,000 gallons

The concentration of the resulting solution is 2.625% salinity

Step-by-step explanation:

The salinity of the fresh water from the Mississippi River Delta = 0%

The salinity  of the water from the Gulf of Mexico = 3 1/2%

Therefore, if 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, we have;

The total resulting gallons of water = 1,000 + 3,000 = 4,000 gallons

The total resulting gallons of water = 4,000 gallons

The concentration of the resulting solution is found as follows;

The concentration of the resulting solution = (3 × 3 1/2)/400 × 100 = 2.625%

The concentration of the resulting solution = 2.625% salinity.

Step-by-step explanation:

Rotation is one of the three rigid transformation of which others are reflection and translation. In a rotation transformation of a figure about a fixed point, known as the center of rotation, the figure is turned in a circular path about the fixed point or center of rotation. The size and shape of the pre-image the rotation are the same however, depending on the angle of rotation, their facing directions may be different. The specification of a rotation can be in the clockwise direction or in the anti-clockwise direction

The shape of the triangle in the question and the image are the same and are therefore congruent. All interior angles of the triangle and those of its rotation will therefore be congruent.
