Write the expression in Distributive Property form (as a Distributive Property problem). 39d - 13e + 195g

Answers

Answer:

13(3d - e + 15g).

Step-by-step explanation:

Distributive property example,

a(x + y + z) = ax + ay + az

By this property we have to convert the given expression into a distributive property form.

39d - 13e + 195g

Take the common factor out from each term of the expression,

39d - 13e + 195g = 13(3d - e + 15g)

Therefore, distributive property form of the given expression is 13(3d - e + 15g).

Which equation represents a line which is perpendicular to the line 6x+y=1

A.Y=1/6x+4
B.Y=-6x-2
C. Y=-1/6x-7
D.Y=6x-6

Answers

I believe it’s A because if it is perpendicular you would have to flip 6X and change the sign so therefore it would be A. In slope intercept form it would be y=-6x+1.

3. Mr. Pau has
some clay with a mass
of 24 kilograms. If he puts the same
amount of clay into 6 bags, how
many grams of clay are in each bag?
A 4,000 grams
1,440 grams
© 144 grams
0 400 grams

Answers

Answer:

A. 4,000 grams

Step-by-step explanation:

1 kilogram = 1,000 grams

24 kilograms = 24,000 grams

Mass of clay = 24 kilograms = 24,000 grams

Number of bags = 6

how many grams of clay are in each bag?

Grams of clay in each bag = Total mass of clay / number of bags

= 24,000 grams / 6 bags

= 4,000 grams per bag

Grams of clay in each bag = 4,000 grams

Pedro measured a swimming pool and made a scale drawing. The pool, which is 42 meters long in real life, is 119 centimeters long in the drawing. What scale did Pedro use for the drawing?

Answers

Answer:

The scale that Pedro used for the drawing is: 17:600.

Step-by-step explanation:

A scale of a drawing is expressed as: Drawing length:actual length.

Since you know that the pool is 119 centimeters long in the drawing and 42 meters long in real life, first you have to find  the cm in 42 meter taking into account that 1 meter is equal to 100 cm:

1 m     →    100 cm

42 m   →          x

x=(42*100)/1

x=4200 cm

Now, the scale would be:

119:4200

Finally, you need to simplify and you can do it by dividing each number by 7:

17:600

According to this, the answer is that the scale that Pedro used for the drawing is: 17:600.

What is the least common denominator for 1/6 and 3/8​

Answer:

24

Step-by-step explanation:

bc if you were to find what the fractions were before they were simplified, it would be 4/24 (for 1/6) and 9/24 (for 3/8)

The least common denominator for  1/6 and 3/8​ is 24.

What is the least common denominator?

When two or more fractions are supplied, the least common denominator is the smallest number among all the common multiples of the denominators.

Given, two fraction numbers 1/6 and 3/8​

We need to find the least common denominator of them. for that,

We will take the LCM of the denominator of both factors.

LCM of 6 and 8 = 24

Therefore, for fractions 1/6 and 3/8​, 24 is the least common denominator.
