Mice21 [21]

Answer:

8

Step-by-step explanation:

Since 24 is the original length, you would have to see what number to divide by to get 6.

24 divided by 4 is 6.

Now we know that 1/4 is the scale factor, so apply that to 32.

32 divided by 4 is 6

That's your answer!

4(2p+3)=16<br> solve the equation

Natali5045456 [20]

Final Answer: $p = \frac{1}{2}$

Steps/Reasons/Explanation:

Question: Solve the equation $4(2p + 3) = 16$ .

<u>Step 1</u>: Divide both sides by $4$ .

$2p + 3 = \frac{16}{4}$

<u>Step 2</u>: Simplify $\frac{16}{4}$ to $4$ .

$2p + 3 = 4$

<u>Step 3</u>: Subtract $3$ from both sides.

$2p = 4 - 3$

<u>Step 4</u>: Simplify $4 - 3$ to $1$ .

$2p = 1$

<u>Step 5</u>: Divide both sides by $2$ .

$p = \frac{1}{2}$

In which of the options below will the number 3 correctly fill in the blank. Select all that apply. A) ___ : 4 = 12 : 16 B) 1 :

aniked [119]

Answer:

A and B

Step-by-step explanation:

Given

List of given options

Required

Which will correctly take 3 to fill the blank

Represent the blanks with x

Option A:

$x : 4 = 12 : 16$

Convert to fractions

$\frac{x}{4} = \frac{12}{16}$

Multiply through by 4

$4 * \frac{x}{4} = 4 * \frac{12}{16}$

$x = \frac{48}{16}$

$x = 3$

Option B:

$1 : 5= x : 15$

Convert to fraction;

$\frac{1}{5} = \frac{x}{15}$

Multiply through by 15

$15 * \frac{1}{5} = \frac{x}{15} * 15$

$15 * \frac{1}{5} = x$

$3 = x$

$x = 3$

Option C:

$x : 1 = 12 : 3$

Convert to fraction

$\frac{x}{1} = \frac{12}{3}$

$x = 4$

Option D

$15:x = 3:1$

Convert to fraction

$\frac{15}{x} = \frac{3}{1}$

Cross Multiply

$3 * x = 15 * 1$

$3 * x = 15$

Divide through by 3

$x = 5$

From the above calculations.

<em>Option A and B can be filled with 3</em>
