40 minutes! 150-30 = 120. Then 120/3 = 40

Answer:

40 minutes

Step-by-step explanation:

→ Take the total away from the amount he wants left

150 - 30 = 120

→ Divide this by his rate

120 ÷ 3 = 40 minutes

Simplify into a binomial
Eduardwww [97]

Answer:

x-5

Step-by-step explanation:

Consider the expression

\dfrac{3x^3-15x^2+15x-75}{3x^2+15}

Its numerator 3x^3-15x^2+15x-75 is equivalent to

3x^3-15x^2+15x-75\\ \\=3x^2(x-5)+15(x-5)\\ \\=(x-5)(3x^2+15)

Therefore, given expression can be rewritten as

\dfrac{(x-5)(3x^2+15)}{3x^2+15}=x-5

Note that 3x^2+15\neq 0, so we can divide the numerator and the denominator by non-zero expression 3x^2+15.

Look at the picture for the problem
Serjik [45]

Answer:

w = 400

Step-by-step explanation:

2400 = lw

Divide the area by two.

2400 / 2 = 1200

Now this cannot be the answer since the length is longer than the width.

Divide 1200 by two again.

1200 = 600

Notice there are two choices that are the closest:

w = 800

w = 400

The latter choice would be the answer since again, the length is longer than width in terms of measurement

  ∠1 and ∠6 are supplementary angles

  ∠3, ∠4, and ∠5 are supplementary angles

2. m∠1 = m∠3                                        2. definition of congruency

3. m∠1 + m∠6 = 180°                             3. definition of supplementary angles

   m∠3 + m∠4 + m∠5 = 180°

4.  m∠3 + m∠4 + m∠5 = m∠1 + m∠6     4. transitive property

5.  m∠3 + m∠4 + m∠5 = m∠3 + m∠6     5. substitution property

6.  m∠4 + m∠5 = m∠6                             6. subtraction property of equality
