Answer:

A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.

Step-by-step explanation:

Given equation is 4x + 5y = 10

we have to convert it in slope intercept form

slope intercept form is given by y = mx + c

now seeing the slop intercept form ,

we can say that

we have to isolate y , for that we have to remove 4x from

4x + 5y = 10 from RHS of the equation

to do that we have to subtract 4x from both side as shown below

4x + 5y - 4x = 10 - 4x

this step is called  Subtraction Property of Equality to subtract 4x from both sides of the equation

and hence option A is the correct choice

Answer:

A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.

Step-by-step explanation:

Nature's Best wants to combine nuts they sell for $3.60 a pound with dried fruit they sell for $2.40 a pound to create a trail mix. How much of each snack should they use to make 10 pounds of trail mix that would sell for $3.30 a pound?

--------------

Let amt. of nuts be "x" lbs ; value is 3.60x dollars

-------------

Amt of fruit is "10-x" lbs ; value is 2.4(10-x) = 24-2.4x dollars

----------------------

Amt of mix is 10 lbs ; value is 3.3*10= 33 dollars

------------------------

EQUATION:

value + value = 33 dollars

3.6x + 24-2.4x = 33

1.2x = 9

x = 7.5 lbs (amt of nuts in the mix)

10-x = 2.5 lbs (amt of fruit in the mix)

Answer:

[tex]\huge\boxed{\texttt{See Explanation}}[/tex]

Step-by-step explanation:

In order to simplify a radical, we're looking for a perfect square within that number.

Say we have [tex]\sqrt{108}[/tex].

We're looking for two numbers, where

1. We can easily find the square root of the first number

2. When we multiply that number by the second, we get 108.

We can experiment with numbers for 108. We know that [tex]36 \cdot 3 = 108[/tex], so we can form this statement now.

[tex]\sqrt{108} = \sqrt{36 \cdot 3}[/tex]

We know the square root of 36 is 6. Therefore, we can put this outside the square root sign and leave 3 inside.

[tex]\sqrt{36} = 6\\6\sqrt{3}[/tex]

Hope this helped!

Answer: Hello fellows! your answer is D. 60

HAVE A GREAT DAY!

On average, less than 60 percent of eligible voters participate in elections, hence option D is correct.

Eligible voters are who belong to the country where the elections are held and have the right age for voting, they have the right to vote according to the government rules and regulations.

According to the survey, the eligible voters' participation in the election is only 60% of the total voters.

Voting is the right of every individual who belongs to the country and chooses the perfect government for their country. It is bad for the individual who is not voting for the country and not showing interest in politics.

Therefore, on average, less than 60 percent of eligible voters participate in elections, hence option D is correct.

Answer:

  d.  z = -48

Step-by-step explanation:

When j ║ k, corresponding angles are congruent, so ...

  x = 4z +3y

  57 = y + z

and the same-side interior angles are supplementary:

  57 +x = 180   ⇒   x = 123

__

This lets us write two equations in y and z:

  3y +4z = 123

  y +z = 57

Using the second equation to write an expression for y, we have ...

  y = 57 -z

Substituting this into the first equation gives ...

  3(57 -z) +4z = 123

  z +171 = 123

  z = -48 . . . . . . . subtract 171

The value of z that makes j║k is -48.

___

The corresponding value of y is 105.

Answer:

4,8,14

Step-by-step explanation:

The three numbers are x = 4, y = 8 and z = 14 respectively.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the sum of three numbers as 26. The second number is twice the first and the third number is 6 more than the second.

Assume that the first number is x.

Then, the second number will be equal to 2x

The third number would be equal to (2x + 6)

Now, theirs sum is equal to 26. Therefore, we can write -

x + 2x + 2x + 6 = 26

5x + 6 = 26

5x = 26 - 6

5x = 20

x = 4

Then,

the second number (y) would be equal to (2 x 4) = 8

the third number (z) would be equal to (2 x 4 + 6) = 14

Therefore, the three numbers are x = 4, y = 8 and z = 14 respectively.

Answer:

x=2.5

Step-by-step explanation:

2x+3x-4=x+6

5x-4=x+6

4x=10

x=10/4

x=5/2

x=2.5

Answer:

4x=10 or x= 10/4 or x= 5/2 or x= 2 and 1/2 or also E

Step-by-step explanation:

You can combine like terms by adding 2x and 3x, as they have the same variable with no extra additions onto them. You get 5x.

The current equation should look like 5x-4=x+6

Then you can subtract 1x from both sides, to get rid of the x on the right side to get 4x-4=6

Then you can do a similar operation to add 4 on both sides to get 4x=10.

Finally you can divide both sides by 4 (simplifying to get unit rates of x)

You get x = 10/4

You simplify to get 5/2 and it can simplify to a mixed number if needed which is 2 and 1/2

Answer:

Three sheets will be left over.

Step-by-step explanation:

Well, if you have 80 sheets of paper, and seven students need it, you would first divide the 80 sheets to the seven students using the equation 80 ÷ 7 = 11.4. You won't be giving fractions of paper to the students so you would round to 11. If each of the seven students gets 11 sheets of paper, 77 sheets will have been used. 80 - 77 = 3. So, there will be three sheets left over.

The slope intercept form of the given line equation is y = x/2 - 1.

The given equation of a line is x-2y=2.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Here, the equation can be written in slope intercept form as

x-2y = 2

2y = x-2

y = x/2 - 2/2

y = x/2 - 1

Therefore, the slope intercept form of the given line equation is y = x/2 - 1.
