Answer 1

Answer:

X - 3X = 2(4+X)

Distributive Property:

X-3X = 8+2X

Subtraction Prperty:

-2X = 8+2X

Subtraction Property:

-4X = 8

Division Property:

x = 8/-4

X = -2

Answer 2

Answer:

Hi,

Let's solve the equation step-by-step.

x−3x=2(4+x)

Step 1: Simplify both sides of the equation.

x−3x=2(4+x)

x+−3x=(2)(4)+(2)(x)(Distribute)

x+−3x=8+2x

(x+−3x)=2x+8(Combine Like Terms)

−2x=2x+8

Step 2: Subtract 2x from both sides.

−2x−2x=2x+8−2x

−4x=8

Step 3: Divide both sides by -4.

−4x/−4 = 8/−4

x=−2

Answer:

x=−2

Have a great day!

Find the factors of 42 show and explain your work and list the factor pairs in a table

Answers

Answer:

The factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs are 1 and 42, 2 and 21, 3 and 14, 6 and 7.

Step-by-step explanation:

The given number is 42.

The numbers that can divide 42 completely, are the factors of 42.

Since we know that 42 is completely divisible by 1, 2, 3, 6, 7, 14, 21 and 42, therefore the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.

The list of factor pairs are shown below:

$1* 42=42$

$2* 21=42$

$3* 14=42$

$6* 7=42$

Therefore the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs are 1 and 42, 2 and 21, 3 and 14, 6 and 7.

Factors of 42 are...
1, 2, 3, 6, 7, 14, 21, and 42.
1 x 42 = 42
2 x 21 = 42
3 x 14 = 42
6 x 7 = 42

Don't know how you want your table.
I'm sure you can do it yourself.

Which point is located at (2, 3)?
1 A
2 B
3 C
4 D

Answers

Hi abycflo! Please read the following :)

We know that the first coordinate location given should always be on the x-axis.

The x-axis is the line you can see that is going horizontal or sideways.

So we know that we have to line up 2 on the x-axis and we immediately know its going to be either B or C.

The y-axis is the line going up or vertically. So on the 3 for the y-axis, we found out that our answer is

C, given from the following coordinates given we can affirmatively say its C.

P.S

Have an Amazing day abycflo! I Hope this Helps and Good Luck!

Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs. Suppose Karl onlyhas a dozen eggs. How many batches of cookies could he make?

Answers

Answer:

$5\ batches\ of\ cookies$

Step-by-step explanation:

we know that

Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs

so using proportion

Find out how many batches of cookies could he make with a dozen eggs

step 1

Convert mixed numbers to an improper fraction

$7(1)/(2)=(7*2+1)/(2)=(15)/(2)$

$1(1)/(2)=(1*2+1)/(2)=(3)/(2)$

step 2

Applying proportion

Let

x ----> the amount of batches of cookies

$((15/2))/((3/2))(batches)/(dozen\ eggs)=(x)/(1)(batches)/(dozen\ eggs)\n\nx=(15)/(3)\n\nx=5\ batches\ of\ cookies$
