The value of equation when n = 3 is 50

<em><u>Solution:</u></em>

<em><u>Given equation is:</u></em>

(4n -2)(7-2)

We have to find the value of equation when n = 3

By plugging in n = 3 in given equation we can find the value of given equation

<em><u>Substitute n = 3 in given equation</u></em>

\rightarrow (4(3) -2)(7-2)\\\\Solve\ the\ above\ equation\\\\\rightarrow (12-2)(7-2)\\\\\rightarrow (12 - 2)(5)\\\\Simplify\ the\ above\ equation\\\\\rightarrow 10 \times 5 = 50

Thus the value of equation when n = 3 is 50

ANTONII [103]

Answer:

  $102

Step-by-step explanation:

The pay for the day of work is the total of morning hours worked and afternoon hours worked. In each case, the hours worked is the difference between the "Out" time and the "In" time.

  morning hours = 12:15 -8:15 = 4:00

  afternoon hours = 17:30 -13:00 = 4:30

  total hours worked = morning hours + afternoon hours

  total hours worked = 4:00 +4:30 = 8:30

This notation tells you (hours):(minutes). You know that 30 minutes is 1/2 hour, so the total time worked is 8 1/2 hours.

The pay is the product of the hours worked and the pay per hour:

  pay = (8 1/2 hours) × ($12 /hour) = $102

457 gummy bears ÷ 5 people = 94 gummy bears each with a remainder of 4

You could divide the remaining 4 gummy bears amongst each person but one would be left out.

Finger [1]

Answer:

\textsf{b.} \quad 3x+5y=2

Step-by-step explanation:

<u>Define the given points</u>:

\textsf{let}\:(x_1,y_1)=(4,-2)

\textsf{let}\:(x_2,y_2)=(-1,1)

Use the <u>slope formula</u> to determine the slope of the line:

\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-(-2)}{-1-4}=\dfrac{1+2}{-1-4}=-\dfrac{3}{5}

Use the <u>point-slope formula</u> to determine the equation of the line.

\implies y-y_1=m(x-x_1)

Substitute the found slope and point (4, -2):

\implies y-(-2)=-\dfrac{3}{5}(x-4)

\implies y+2=-\dfrac{3}{5}(x-4)

Multiply both sides by 5:

\implies 5(y+2)=-3(x-4)

Expand the brackets:

\implies 5y+10=-3x+12

Add 3x to both sides:

\implies 5y+10+3x=-3x+12+3x

\implies 3x+5y+10=12

Subtract 10 from both sides:

\implies 3x+5y+10-10=12-10

\implies 3x+5y=2

Answer:

G: 4,13 (4 lbs costs 13 dollars)

H: 1,3 (1lb costs 3 dollars)

Step-by-step explanation:

first, the horizontal line (the one going left to right) is the x axis.

the vertical line (up and down) is the y axis

look at the x axis first the point G is on the 4th mark

and then look at the y axis, the point G is on the 3rd mark

therefore, the coordinate is: 4,3

*tip: always put the x axis before the y!! a way to remember that is in the alphabet, x comes before y

(I know I already answered this in the comments but I wanted to explain it further, so here you are! )
