Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?

Answers

Answer:

6 hours.

Step-by-step explanation:

The formula sort of has to be invented.

Al

rate = 1 shed / 2 hours

Tom

rate = 1 shed / x hours.

Together.

rate = 1 shed / 1.5 hours.

Equation

1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.

1/2 + 1/x = 1/1.5          Put the fractions over a common denominator.

(x + 2) / 2x = 1 / 1.5   Cross Multiply

1.5(x + 2) = 2x           Remove the Brackets.

1.5x + 3 = 2x             Subtract 1.5x from both sides

3 = 2x - 1.5x

3 = 0.5x                    Multiply both sides by 2

6 = x

It would take Al 6 hours to do the shed on his own.

geometry solve for x

Answers

Answer:

x = 74 degrees

Step-by-step explanation:

If we assume that this triangle is isosceles, then the sum of the two angles at the bottom is (180 - 32) degrees, or 148 degrees.  The angle x is half that, i. e., x = 74 degrees

Can someone help me with this please

Answers

Answer:

Step-by-step explanation:

9) In parallelogram, adjacent angles are supplementary

14x - 4 + 86 = 180

           14x  = 180 - 86 + 4

           14x = 98

               x = 98/14

              x = 7

10) In parallelogram, opposite angles are congruent.

6x + 4 = 64

      6x = 64 - 4

     6x = 60

      x = 60/6

    x = 10

11) In parallelogram, opposite sides are congruent.

3x + 4 = 2x + 10

 3x -2x + 4 = 10

           x + 4 = 10

                   x = 10-4

                  x = 6

PLEASE HELP ILL GIVE BRAINLIEST! PLEASE PUT X AND Y PLOT POINTS! x-3y=3 2x+9y=11

Answers

Answer:

( x, y ) = ( 4, 1/3)

Step-by-step explanation:

x - 3y = 3

2x +9y = 11

1. substitute the value of x

   x= 3 + 3y

   2x + 9y = 11

2. solve equation

   2 (3 + 3y) +9y = 11

3. substitute the value of y

  y = 1/3

4. solve equation

  x = 3 + 3 x 1/3

   x = 4

5. check solution

 (x, y)  = ( 4, 1/3 )

 check  x ---->  4 - 3 x 1/3 = 3

  check y ------> 2 x 4 + 9 x 1/3 = 11

    for x----> 3=3

     for y----> 11=11

Find the discriminant and determine the number of real roots for each equation. Show steps.

-3p^2 - 2p = 0

Answers

Answer:

discriminant:  4; number of real roots:  2

Step-by-step explanation:

The coefficients a, b and c of this quadratic are {-3, -2, 0}.

Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.

Because the discriminant is positive, this quadratic has two real, unequal roots.

-3p^2 - 2p can be factored as follows:  -p(3p + 2).  If we set this expression equal to zero, we can find the roots:  {-2/3, 0}

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of golf balls = 468

Number of golf balls in one box = 18

The number of boxes.

= 468 ÷ 18

= 468/18

= 26


Thus,

The number of boxes needed is 26.
