To solve for a variable means to ISOLATE the variable on one side of the equation. To do so, divide both sides by the coefficient of y.

Look:

2y/2 = (-x+7)/2

Answer: y = (-x + 7)/2

The answer can also be written as

y = -(x/2) + (7/2)

Both answers mean the same thing.

Answer:

172

Step-by-step explanation:

a triangle all together has 180 degrees on it

10+8=18

180-18=172

(it doesn't sound right but that's how I learned it)

Answer:

The length of the third side is 6

Step-by-step explanation:

Using Pythagorean theorem:

[tex]c^{2} =b^{2} +a^{2}[/tex]

where,

c = the longest side ( 10 )

b = one of the other sides ( 8 )

a = the last side ( the missing one - assume it's a )

step1: sub the values in the formula:

[tex]10^{2} =8^{2} +a^{2}[/tex]

step2: simplify the numbers:

[tex]100=64+a^{2}[/tex]

step3: subtract 64 from both sides:

[tex]a^{2} =36[/tex]

step4: take the square root for both sides:

a = √36

step5: simplify to get a:

a = 6

so the length of the third side is 6

Answer:

$320 400

Step-by-step explanation:

A leap year is something which is on 29th February they occurs every 4 years.

How much he earns a day = 150 x 2 = 300

A week = 300 x 7 = 2100

A month = 2100 x 4 = 8400

A year = 8400 x 12 = 100 800

3 years = 100 800 x 3 = 302 400

How many days for 29th February to come =

31 + 29 = 60 days

60 days = 300 x 60 = 18 000

302 400 + 18 000 = 320 400

Answer:

109,800.

Step-by-step explanation:

So to solve this first you have do 150 x  365 because there are 366 day in a  leap year.

150 x 366 = 54900

54900 would be how many apples he would have sold in 1 year. Now we have to multiply that by $2 because for every one apple he sells he get's 2 dollars.

54900 x $2 =  109,800

To check the answer solve it another way

150 x 2 = $300

That's how much money he makes in one day now multiply that by 366 because thats how many days are in a leap year.

$300 x 366 = 109,800.

Hope that helped!!!!

Answer:

[tex]A)5\frac{1}{2}[/tex]

Step-by-step explanation:

To multiply a number and a mixed number, first convert the improper fraction to a mixed number. This can be done by multiplying the "number" part of the mixed number by the denominator (number underneath the fraction bar) and then adding the result to the numerator. After doing so, one can either multiply the improper fraction by the number, and then simplify the result, or one can cross simplify the number and the denominator, then multiply by the numerator.

[tex]4 * 1\frac{3}{8}\\\\4 * \frac{11}{8}\\\\=\frac{44}{8}\\\\= \frac{11}{2}[/tex]

Now one must convert this improper fraction to a mixed number. One can do this by diving the numerator by the denominator, writing the result as the "number" part of the mixed number, and then writing the remainder as the numerator of the fraction.

[tex]5\frac{1}{2}[/tex]

WHAT THE HECK WHERE IS THE QUESTION

Answer:

PERIOD POOH

Step-by-step explanation:

Answer:

x=9, y=26. (9, 26).

Step-by-step explanation:

x=9

y=3x-1

--------

y=3(9)-1=27-1=26

Answer:

y = 26

Step-by-step explanation:

Plug the value of X into the equation.

y = 3(9) - 1

Then, simplify the equation.

y = 27 - 1

y = 26

Answer:

Step-by-step explanation:

Your y-intercept is a positive three, so your starting point would start on positive three on the y-axis. Since your slope is a negative one, your line should be heading towards the bottom right corner (much like your last question).

To find the next point on the graph, you need to go down one and over one. Or, one space.

Answer:

Step-by-step explanation:

The lines are parallel to one another.

A linear system of equations has no solution if the graphs are parallel and the two lines never meet.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

There can be one solution to a system of two linear equations, an infinite number of solutions, or no solutions at all. The number of solutions to a system of equations can be used to categorize it.

A system is deemed consistent if there is at least one solution to the problem. A consistent system is said to be independent if it only has one possible outcome.

Thus, a linear system of equations has no solution if the graphs are parallel and the two lines never meet.
