can you please help me​

Answer:

t = 7

Step-by-step explanation:

5(2t - 3) – 7.5t = 0.5(12 – t)

5*2t - 3*5 - 7.5t = 12*0.5 - t *0.5

10t - 15 - 7.5t = 6 - 0.5t           {Now, combine like terms}

10t - 7.5t - 15 = 6 - 0.5t

         2.5t -15 = 6 - 0.5t      {Add 15 to both sides}    

         2.5t      = 6 - 0.5t + 15

              2.5t = 21 - 0.5t       { Add 0.5t to both sides}

    2.5t + 0.5t = 21  

                 3t = 21     {Divide both sides by 3}

                   t = 21/3

t = 7

Work for E and F- 20/50=20X2=40                40 divided by 100 is 40%

                                           50X2=100               and 40/100

Answer:

A, C, and D.

-60/100

-60%

1. 50-20=30

2. There are 30/50 slices left.

3. 30/50 = 60/100

4. 60/100 written as a decimal is 0.6.

Answer:

60 inches

Step-by-step explanation:

Natalie will need to buy 60 inches of ribbon. This was calculated as 12 x 5 = 60

There are 12 inches in a foot, so I just multiplied that by how many feet she needs.

Answer:

21 i think

Step-by-step explanation:

to solve for the sine you have to look at the hypotenuse aka the opposite side.

Sorry I cannot solve for the Sin, I am a child of God, a brother to Jesus. I do not believe in sins, since I have never sinned in my life. I have been enlightened from the gods themselves. They taught me right from wrong and wrong from right. Anybody can be forgiven for their sins, such as now. Your sins are now forgiven by a higher being.

Step-by-step explanation:

If they made the same amount on their last game as  their first they'd be the same.

Answer:

If I am reading it right, they would have made the same amount of money considering it said "At their last game, they made as much money as they made at their first game."

Answer:

100 3/10, 1003/10, or 100.3

Step-by-step explanation:

Converting your word to numbers, we have the equation:

x = 100 + 3/10

We could automatically leave it as a mixed number. Or, if you want to get a bit more complicated, you could turn it into an improper fraction or decimal:

1003/10 or 100.3

Answer:

[tex](-\frac{1}{3},\frac{1}{2} )[/tex] , [tex](-\frac{3}{2} ,3)[/tex]

Step-by-step explanation:

2y = 3x + 1

y = 2x + 3

Graph 2y = 3x + 1.

Divide each term by 2 and simplify.

      [tex]y=\frac{3x}{2}+\frac{1}{2}[/tex]

Rewrite in slope-intercept form.

      [tex]y=\frac{3}{2}x+\frac{1}{2}[/tex]

Use the slope-intercept form to find the slope and y-intercept.

Find the values of m and b using the form y = mx + b.

       [tex]m=\frac{3}{2}[/tex]

        [tex]b=\frac{1}{2}[/tex]

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: [tex]\frac{3}{2}[/tex]

y-intercept: [tex](0,\frac{1}{2} )[/tex]

Any line can be graphed using two points. Select two x values, and plug them into the  equation to find the corresponding y values.

Find the x-intercept.

x-intercept(s):  [tex](-\frac{3}{2},0 )[/tex]

y-intercept(s): (0, 3)

Create a table of the x and y values.

  _x_|_y_

  [tex]-\frac{3}{2}[/tex]  |   [tex]0[/tex]

     [tex]0[/tex]  |   [tex]3[/tex]

Graph the line using the slope and the y-intercept, or the points.

Slope: 2

intercept: (0, 3)

  _x_|_y_

  [tex]-\frac{3}{2}[/tex]  |   [tex]0[/tex]

     [tex]0[/tex]  |   [tex]3[/tex]

Graph y = 2x + 3

Use the slope-intercept form to find the slope and y-intercept.

Slope: 2

intercept: (0, 3)

x-intercept(s): [tex](-\frac{3}{2},0)[/tex]

y-intercept(s): (0, 3)

Plot each graph on the same coordinate system.

Answer:

45 units squared

Step-by-step explanation:

Basically you know that two parts of the square is equal to a whole, as 50 plus 50 is 100.

So on the left diagonal, it is equal to 3 units squared, since there are 6 parts and each unit diagonal is equal to 1/2 of a square.

On the right side, there are also 3 units squared, since there are 6 parts and blah blah blah.

Even if it looks different, two partial squares will still add up to one whole square. So the diagonals are equal to 6 units.

Then you can add up your full squares that you already know of so there are 9 units on the bottom row and another 9 on top.

Then you add 7 for the third layer and 6 more on the next.

There are 4 on the next layer and 3 and another square.

So 9 + 9 + 7 + 6 + 4+ 3 + 1.

That is 39.

But you may say: BUT WAIT SCOTTY THERE IS ANOTHER 6

me: oh yah i frgot bro thanks m8

So since there is another 6 more units, it is 45 since 39 + 6 is 45.

Hope this helps boi

Answer:

Frank is correct.

Step-by-step explanation:

To convert 4.3 x [tex]10^{4}[/tex] into regular notation I move the decimal 4 places to the right and get 43,000. This is way more than enough for the 5,000 yards needed for the carpet. So, Frank's wife is wrong about it not being enough.

Answer:

The husband is correct. They needed 5,000, and he brought 43000.

Step-by-step explanation:

4.3*(10^4)=43000

Answer:

h + c ≤ 8

3h + 6c ≥ 40

where h is the number of hiking hours

c is the number of canoeing hours

Step-by-step explanation:

Here, we want to write a system of inequalities;

Let number of hiking hours be h and the number of canoeing hours be c

h + c ≤ 8

Covering at least 40 miles;

Recall;

distance = speed * time

for 3 miles, h hours, we have 3h miles

for 6 miles , c hours , we have 6c

At least 40 miles, inequality will be ;

3h + 6c ≥ 40
