Tommy thought of a number. He multiplied the number 4, then added six. The result was fifty. What was Tommy's starting number?

Answer:

x + 7 = y // y x 8

Step-by-step explanation:

x = ?

y + ?

x and y are the variables, since we don't know what the values are

Hope this helps!!

Answer:

  p (-1)  = -156

Step-by-step explanation:

Explanation:-

Given polynomial

           p(x)=7x³ -6x²+39x-104

Put x=-1

          p (-1)    = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104

                     = - 7 - 6 - 39 - 104

          p (-1)  = -156

9514 1404 393

Answer:

Step-by-step explanation:

The interior angle of the m-gon is ...

  m-interior = 180 -360/m

The exterior angle of the k-gon is ...

  k-exterior = 360/k

The required relationships are ...

  m = 3k

  m-interior = 14/3(k-exterior)

Substituting for m, we can write the latter relation as ...

  (180 -360/(3k)) = 14/3(360/k)

Multiplying by 3k/180, we have ...

  3k -2 = 28

  k = (28 +2)/3 = 10

The values of k and m are 10 and 30, respectively.

_____

Check

The interior angle of the m-gon is 180 -360/30 = 168 degrees.

The exterior angle of the k-gon is 360/10 = 36 degrees.

The angle ratio is 168/36 = 14/3 as required.

Answer:

1) x-intercepts are at -3 and -4

2) x-intercepts are at 5/3 and 2

Step-by-step explanation:

1) y = -x^2 - 7x - 12  is -(x + 3) (x + 4)

2) y = 3x^2 + 11x + 10  is (3x + 5) (x + 2)

Answer:

4 * sqrt(3) / 3

Step-by-step explanation:

sin 60 = opposite / hypot = 2 / x

sin 60 is sqrt(3) / 2

2 / x = sqrt(3) / 2 -> 4 = x * sqrt(3)

x = 4 / sqrt(3) = 4 * sqrt(3) / 3

Answer:

y = -2x + 7

Step-by-step explanation:

to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis

a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)

so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)

now, an equation for a line is written as Y = MX + B

M = slope

B = y intercept

our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation

y = -2x + 7

Answer:

y= -2x + 7

Step-by-step explanation:

Rewrite the fractions to have a common denominator to find the difference:

2/3 = 4/6

Difference = 4/6-5/6 = -1/6

Sequence formula = an = a1 + d(n-1)

A1 is the first term 5/6

And d = -1/6

Sequence = 5/6 -1/6(n-1)

Simplify to get an =(-n +6)/6

Answer:

y = 8x

Step-by-step explanation:

Given that :

Ornanment are packed in boxes

Number of ornament per box = 8

x = number of boxes packed

y = Number of ornaments

Number of Ornanments packed = (Number ornaments per box * number of boxes packed

y = 8 * x

y = 8x

Angle 4 is 133

Angle 2 is 52

Angle 1 is 128

Answer:

4x-2=26

Step-by-step explanation:

All 3 sides of the triangle are identical so each interior angle is 60 degrees.

7x + 4 = 60

Subtract 4 from both sides:

7x = 56

Divide both sides by 7:

x = 8

Answer:

x=10

Step-by-step explanation:

Pull out like factors :

  -9x + 90  =   -9 • (x - 10)

Equations which are never true:

2.1      Solve :    -9   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-10 = 0

Add  10  to both sides of the equation :

                     x = 10

Step-by-step explanation:

The best player on a basketball team makes 95​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 95% × 40

= 95/100 × 40

= 0.95 × 40

= 38

The​ second-best player makes 90​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 90% × 40

= 90/100 × 40

= 0.90 × 40

= 36

The​ third-best player makes 80​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 80% × 40

= 80/100 × 40

= 0.80 × 40

= 32

Answer:

$71.40

Step-by-step explanation:

Before Tax Price: $68.00

Sale Tax: 5.00% or $3.40

After Tax Price: $71.40

Answer:

71.40

Step-by-step explanation:

Sales tax = 5% of 68

              [tex]=\frac{5}{100}*68\\\\=\frac{340}{100}\\\\= 3.40[/tex]

Sales tax = $ 3.40

Total cost = 68 + 3.40 = $ 71.40
