The Equivalent Expression is 12 + 12x + 6y.

Therefore, option A is correct.

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the expression: 6(2 + x + x + y)

Using Distributive property

a x ( b + c + d) = ab + ac + ad

So, the simplified expression is

= 6(2 + x + x + y)

= 6(2) + 6(x) + 6(x)+ 6(y)

= 12 + 6x + 6x + 6y

= 12 + 12 x + 6y

So, the Equivalent Expression is 12 + 12x + 6y.

Answer: 7/8

Step-by-step explanation:

You can change all the fractions to have equivalent denominators.

The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.

1 1/4 = 1 2/8 = 10/8.

3/8 = 3/8.

Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.

10/8 - 3/8 = 7/8.

Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.

Answer:

30

Step-by-step explanation:

180 degrees = Triangle

Angle 1 = 60

angle 2 = 90 because it's a right triangle

Angle 3 = 180 - (60+90) = 30

60 + 90 = 150

180 - 150 = 30

Answer:

MA = 7, Actual

Step-by-step explanation:

Input force = 50N

Output force = 350N

MA = Output force / Input force

MA = 350 / 50 = 7

The difference between an ideal MA and an actual MA is that the former (ideal MA) uses distance while the latter (actual MA) uses force.

This is an Actual Mechanical Advantage

According to the question,

Input force,

Output force,

As we know the formula,

→ [tex]MA = \frac{Out\ force}{Inp \ force}[/tex]

By substituting the values, we get

          [tex]= \frac{350}{50}[/tex]

          [tex]= 7[/tex]

Thus the above answer is correct as well as it is actual.

Answer:

3.1415967382

Step-by-step explanation:

A unit rate is a rate in which the second quantity, or denominator, in the comparison is 1 unit. You can find the unit rate by dividing the first quantity in a relationship by the second quantity.

The most common second quantity in rates, from personal experience, is the denominator in a fraction, like the 1 in 50/1. This is because the denominator is seen as the one specifying the unit. For example, in the rate "a car goes 50 miles per hour," the numerator would be the distance the car is traveling, which is 50, whilst the denominator would be the time the car takes to drive a certain distance - in this case, 1 hour. The first quantity is 50 miles and the second quantity is 1 hour. We can divide the first quantity by the second to get the fraction 50/1, which is a unit rate because the denominator (second quantity) has a value of 1. This also applies to values such as 90/3, where we would be trying to simplify the fraction to get a denominator value of 1.
