4(4y - 3x) Need help​

Answer:

-235

Step-by-step explanation:

hope that helps :)))

Answer:

3

Step-by-step explanation:

What we can see from your table is that as x goes up by 1 y goes down by one

This means that the slope is -x

We also see that when x=0 y=6 which means that the y intercept is 6

this means your equation is

-x+6

We can now plug in x for 3 and get

-3+6=y

y=3

the answer is 3

Answer: There are 3 quarters , 9 dimes and 14 pennies.

Step-by-step explanation:

Let x= Number of quarters

Then, Number of dimes = 3x

Number of pennies = 3x+5

1 quarter = $ 0.25

1 dime = $0.10

1 penny = $ 0.01

So, Total amount = 0.25x+ 0.10(3x) + 0.01(3x+5)

= 0.25x+0.30x+ 0.03x+0.05

= 0.58x+0.05

Since Total amount = 1 dollar and 79 cents = $ 1.79  [1 cent = $ 0.01]

So,

[tex]0.58x+0.05=1.79\\\\\Rightarrow\ 0.58x= 1.74\\\\\Rightarrow x=\dfrac{1.74}{0.58}\\\\\Rightarrow x=3[/tex]

Thus, there are 3 quarters , 9 dimes , 14 pennies.

Step-by-step explanation:

His total hours he worked is;

21

Step-by-step explanation:

The of hours between 9:00 A.M.  and 4:30 P.M. are;

[tex]\begin{array}{ccc}From \ 9:00 \, A.M. & to \ 10:00\, A.M. & = 1 \, Hour\\From \ 10:00 \, A.M. & to \ 11:00\, A.M. & = 1 \, Hour\\From \ 11:00 \, A.M. & to \ 12:00 \, P.M. & = 1 \, Hour\\From \ 12:00 \, P.M. & to \ 1:00 \, P.M. & = 1 \,Hour\\From \ 1:00 \, P.M. & to \ 2:00 \, P.M. & = 1 \,Hour\\From \ 2:00 \, P.M. & to \ 3:00 \, P.M. & = 1 \,Hour\\From \ 3:00 \, P.M. & to \ 4:00 \, P.M. & = 1 \,Hour\\From \ 4:00 \, P.M. & to \ 4:30 \, P.M. & = 0.5 \, Hour \end{array}[/tex]

Sum of the hours Harold Crispen spends at the workplace on a workday = (1 + 1 + 1 + 1 + 1 + 1 + 1 + 0.5) hours = 7.5 hours

The time Harold Crispen take for launch each workday = 0.5 hour

The number of hours Harold Crispen spend working each day = (7.5 - 0.5) hour

The number of hours Harold Crispen spend working each day = 7.0 hours/day

The number of days he worked = Monday + Tuesday + Thursday = 3 days

The total hours he worked = (The number of hours he works each day) × (The number of days he worked)

His total hours he worked = 7.0 hours/day × 3 days = 21.0 hours.

Answer:

  [tex]\dfrac{5}{2}\left(k-\dfrac{4}{5}\right)[/tex]

Step-by-step explanation:

When you factor out 5/2, each term gets divided by 5/2. Equivalently, each term is multiplied by 2/5.

  [tex]\dfrac{5}{2}k-2=\dfrac{5}{2}\cdot\dfrac{2}{5}\left(\dfrac{5}{2}k-2\right)=\dfrac{5}{2}\left(\dfrac{2}{5}\cdot\dfrac{5}{2}k-\dfrac{2}{5}\cdot2\right)\\\\ =\boxed{\dfrac{5}{2}\left(k-\dfrac{4}{5}\right)}[/tex]

Answer:

Step-by-step explanation:

The angles marked with x-expressions are complementary, so ...

  (3/4x -2) + (2/5x) = 90

  x(3/4+2/5) = 92 . . . . . . . add 2

  x(23/20) = 92 . . . . . . . . combine the fractions

  x = 92(20/23) . . . . . . . . multiply by 20/23

  x = 80

__

The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...

  y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32

  y = 122

Answer:

The system of equations is given as:

x + y = 2.5 .... Equation 1

1.8x + 1.8y = 4.05....Equation 2

Step-by-step explanation:

Kiran says, "I bought 2.5 pounds of red and yellow lentils. Both were $1.80 per pound. I spent a total of $4.05

Let

x represent red lentils

y represent yellow lentils.

x + y = 2.5 .... Equation 1

x = 2.5 - y

$1.80 × x + $1.80 × y = $4.05

1.80x + 1.80y = 4.05....Equation 2

The system of equations is given as:

x + y = 2.5 .... Equation 1

1.8x + 1.8y = 4.05....Equation 2

Answer:

The value of  [tex]x = \frac{1}{6}[/tex]

The length of the rectangle   [tex]= \frac{3}{2}[/tex] cm

The width of the rectangle  = [tex]\frac{16}{3}[/tex] cm

Step-by-step explanation:

Step(i):-

Given that area of the rectangle = 8 cm²

Length of the rectangle (l) = 3x+1

width of the rectangle (w) = 2x+5

The area of the rectangle = length × width

Given that area of the rectangle = 8 cm²

Step(ii):-

Now

                   (3x+1) ( 2x+5)    = 8

       ⇒      3x(2x+5) +1(2x+5) =8

                    6 x² + 15x + 2x +5 =8

         ⇒     6 x² + 17x -3 =0

        ⇒      6 x² + 18x -x -3 =0

       ⇒   6 x ( x+3) -1(x+3) =0

       ⇒   6x -1 =0  and  x +3 =0

              [tex]6x = 1[/tex]  and   x =-3

             [tex]x = \frac{1}{6}[/tex]

The length of the rectangle

                               [tex]= 3 (\frac{1}{6} ) +1 \\= \frac{3}{2}[/tex]

The width of the rectangle

                            [tex]= 2 (\frac{1}{6} ) +5[/tex]

                            = [tex]\frac{16}{3}[/tex]

Answer:

he makes $11.34 and hour and $113.40 in 10 hours

Step-by-step explanation:

you divide 453.6 by 40 to get the 1 hour part and then divide it by 4 to get the 10 hour part

The amount of money that he earns in one hour and in 10 hours will be $11.34 and $113.4, respectively.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Clifford works 40 hours per week while working as a laboratory technician. He earns $453.60 for each week of work.

The amount of money that he earns in each hour is given as,

Rate = $453.60 / 40

Rate = $11.34 per hour

The amount of money that he earns in 10 hours is given as,

⇒ $11.34 x 10

⇒ $113.4

Answer:

y =20 x + 25 (answer B in the list of options)

Step-by-step explanation:

y = 25 + 20 x = 20 x + 25

being 25 the flat fee and 20 the price per bottle

Answer:

B. y = 20x + 25

Step-by-step explanation:

The flat fee of $25 is our b, and the fee of $20 is our m. When we put this in slope intercept form, it looks like y = 20x + 25. That means B is the correct answer.

Answer:

100

Step-by-step explanation:

So in this problem, we have 5 base 10 blocks and 50 ones.

To find out the product we have to count by tens:

10, 20, 30, 40, 50

So 5 base 10 blocks = 50

Now we add the base ten blocks and the ones together:

50 + 50 = 100

So the answer is 100

Answer:

The equation is;

y = 20x + 150

Step-by-step explanation:

Firstly, let us identify the coordinates

(area, cost of area)

We start by getting the points;

(25,650) and (40,950)

The slope will be;

m = (y2-y2)/(x2-x1)

m = (950-650)/(40-25)

m = 300/15 = 20

So the partial equation is;

y = 20x + c

To get the value of c which is the y-intercept, we make use of any of the two points

650 = 20(25) + c

650 = 500 + c

c = 650-500

c = 150
