Solve for each equation 3 1/4 = 1/2 + w

Answers

Answer:

w = - [tex]\frac{58}{31}[/tex]

Step-by-step explanation:

3 1/4 = 1/2 + w

Cross Multiply

31(2 + w) = 4

Divide both sides by 31

[tex]\frac{31(2 + w)}{31}[/tex] = [tex]\frac{4}{31}[/tex] (simplify) -> 2 + w = [tex]\frac{4}{31}[/tex]

Subtract 2 from both sides

2 + w - 2 + [tex]\frac{4}{31}[/tex] - 2 (simplify) -> - [tex]\frac{58}{31}[/tex]

w = - [tex]\frac{58}{31}[/tex]

Find the equation of the line that is parallel to the line y = 2x – 2 and passes through the point (5, -1). Write the equation in point- slope form.​

Answers

Solution:

We know that:

Equation of parallel line: y = 2x - 2

Since the parallel line has a slope of 2, the equation of the original line will also have a slope of 2. Now, let's use point-slope form to find the equation.

y - y₁ = m(x - x₁)y - (-1) = 2(x - 5)y + 1 = 2(x - 5)

Thus, the equation of the line in point slope form is y + 1 = 2(x - 5).

In which number does the digit 3 have a value that is ten times greater than the value of the digit 3 in the number 145,317

Answers

Answer:

Step-by-step explanation:

The value of the digit "3" in "156.32" is 3/10 (3 tenths). 10 times that value would be 3 (3/10 * 10 = 3). So now we need a number that has the digit "3" in it and the value of that digit is "3".

How about 143.26? The digit "3" is in the ones place and so its value is 3*1 or 3. The rest of the number is just made up, nothing special about any of the other numbers.

The value of digit 3 in 156.32 is 3/10 (3 tenths).

10 times that value would be 3 (3/10 * 10 = 3).

What is the value of digits?

The face value of a digit is the magnitude that it possesses naturally. It is independent of the digit's position in the number.

The place value of a digit depends on its position in the number.

So now we need a number that has the digit 3 in it and the value of that digit is 3.

How about 143.26. The digit 3 is in the one place and so its value is 3*1 or 3.

The rest of the number is just made up, nothing special about any of the other numbers.

ASAP NEED HELP AND EXPLANATION WILL GIVE BRAINLIEST

Answers

Answer: 5

Step-by-step explanation:

Carl or felipa ( I need a explanation aswell ) And I’ll give thanks and brainliest!!!!

Answers

Answer:

Carl is incorrect, he didn't write an equivalent expression and he didn't use the distributive property in the equation.

Step-by-step explanation:

When solving equations, we use PEMDAS

P = Parenthesis

E = Exponent

M = Multiply

D = Divide

A = Add

S = Subtract

So lets solve the equation then:

6 - 4 (3 - 6x) + 12x

Use the distributive property to multiply −4 by 3 and -6x

6 - 12 + 24x + 12x

Subtract 12 from 6 to get −6

-6 + 24x + 12x

Combine 24x and 12x to get 36x

-6 + 36x

So, -6 + 36x is the answer

And the reason why Felipa is correct, is because Felip wrote an equivalent expression, she correctly multiplied -4 (3 - 6x) before adding or subtracting and she combined like terms correctly.

The reason why Carl is incorrect, is because he didn't write an equivalent expression and he didn't use the distributive property in the equation.
