Solve the proportion. 3/6 = 7/d

Mathematics

AysviL [449]1 year ago
6 0

To solve this proportion:

\frac{3}{6} =\frac{7}{d}

Simplify 3/6, it reduces to 1/2

\frac{1}{2} =\frac{7}{d}

Then do the Criss cross method

1d = 7 ×2

d=14

Hope it helps!

Answer:

d = 14

Step-by-step explanation:

We can use cross products to solve the proportion

3/6 = 7/d

3*d = 7*6

3d = 42

Divide each side by 3

3d/3 = 42/3

d = 14

28xw+7wy-4kx-ky<br><br> Factor the polynomial completely<br><br> Thank you!
Genrish500 [490]

Answer:

(7w - k)(4x + y)

Step-by-step explanation:

Factor by grouping is best for this expression. To factor by grouping, group pairs of terms with parenthesis. Then find the GCF in each pair. If the parenthesis match after, the factoring is complete.

28xw + 7wy - 4kx - ky

(28xw + 7wy) + (- 4kx - ky)

7w(4x + y) - k (4x + y)

The factors are (7w - k)(4x + y).

Given: ⅓ (18x + 27) = 81 Prove: x = 12
sasho [114]

Answer:

Firstly, rewrite the equation:

⅓ (18 + 27) = 81

Substitute x for the given number of it's supposed equivalent.

In this case x = 12.

⅓ (18(12) + 27) = 81

Solve using PEMDAS and simplify what is in the parenthesis first. Then, multiply.

(18 x 12) + 27 = 243

Now, solving using PEMDAS, multiply the total of what you got that was originally in the parenthesis by ⅓ .

⅓ (243) = 81

When you multiple these number they are equivalent to 81.

81 = 81

Since the equation given, when substituted x for 12, is equivalent to 81, this proves that substituting x for 12 makes this equation true.

Answer:

  16 square units

Step-by-step explanation:

When you plot the points, you see they define a trapezoid with bases of lengths 2 and 6, and a height of 4. The area formula is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(2 +6)(4) = 16

The area of the trapezoid is 16 square units.

Answer:

A≈32\frac{3}{10}ft²

--

To find the surface area of a right rectangular prism you must use this formula A=2(wl+hl+hw)

Then plug in your variebles

A=2( 1.33*1.5+5+1.5+5+1.33)

This comes out to be A≈32 \frac{3}{10}
