How do I get the answer for 1 1/2 x 3 x 1 1/9
Mekhanik [1.2K]

\boxed{1 \frac{1}{2}\times 3 \times 1 \frac{1}{9}=5}

<h2>Explanation:</h2>

in this problem we have the following expression:

1 \frac{1}{2}\times 3 \times 1 \frac{1}{9}

So here:

1 \frac{1}{2} \ and \ 1 \frac{1}{9} \ are \ written \ as \ mixed \ fractions

Let's convert them as improper fractions:

1 \frac{1}{2}=1+\frac{1}{2}=\frac{1\times 2+1}{2}=\frac{3}{2} \\ \\ 1 \frac{1}{9}=1+\frac{1}{9}=\frac{1\times9 +1}{9}=\frac{10}{9}

Rewriting our expression:

\frac{3}{2}\times 3 \times \frac{10}{9}=\frac{3\times 3 \times 10}{2\times 9}=\frac{90}{18}=5

⚠WILL GET BRAINLEST...THE QUESTION IS AT THE BOTTOM ⚠How many solutions does have? O A. Two solutions B. No solutions C. Infinit
Keith_Richards [23]

Answer:

D one solution.

Step-by-step explanation:

It's linear. It is going to have at most 1 solution

8 + x/6 = x/6 - 4 + 5x/12                  Subtract x/6 from both sides

8 = -4 + 5x/12                                   Add 4 to both sides

8+4 = 5x / 12                                    Combine

12 = 5x / 12                                      Multiply both sides by 12

12 * 12 = 5x * 12 / 12                         Cancel

144 = 5x                                            Divide by 5

144/5 = 5x/5

Suppose that g(x) = KX-6) - 3. Which statement best compares the graph
sukhopar [10]

Answer:

C

Step-by-step explanation:

Since g(x) =f(x-horizontal shift) - vertical shift.

So it will shift on the x-axis - 6 units so 6 units to the left and on the y-axis - 3 units so 3 units down.
