Answer:

The 20 ounce is the best package to buy.

Step-by-step explanation:

Divide the cost of the noodles by the ounces and you'll get your answers and then you have to pick the one with the least cost per noodles.

The 6 ounce costs .32 each

The 14 ounce costs .33 each

And the 20 ounce costs .31 each

Answer:

x = 36

Step-by-step explanation:

You can write this equation to represent this problem:

[tex]\frac{1}{2}x-3=14[/tex]

Then, just solve for x:

[tex]\frac{1}{2}x=14+3\\\frac{1}{2}x=17\\x=36[/tex]

Step-by-step explanation:

the function is

ride cost c = mile rate r × miles m + flat rate f

c = r×m + f

now let's put the values in we know and solve for r and f :

9 = r×3 + f

17 = r×7 + f

now, since one term is the same in both equations, we use a simple trick for speed, and we subtract the whole first equation from the second :

17 = r×7 + f

- 9 = r×3 + f

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

8 = r×4 + 0

r = 8/4 = $2

9 = 2×3 + f = 6 + f

f = $3

the first rate is $3, and it costs $2 per mile.

Slope is the change in y over the change in x.

Slope = (-1 - -2) / (4 - -5)

Slope = 1/9

If x is the only thing in the denominator, then,

[tex]f(x) = \frac{1}{x}+2\\\\f(3+h) = \frac{1}{3+h}+2\\\\f(3+h) = \frac{1}{3+h}+2\left(\frac{3+h}{3+h}\right)\\\\f(3+h) = \frac{1+2(3+h)}{3+h}\\\\f(3+h) = \frac{1+6+2h}{3+h}\\\\f(3+h) = \frac{7+2h}{3+h}\\\\[/tex]

We replace every copy of x with 3+h, as shown in the second step. Afterwards, we can optionally simplify to form one big fraction.

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

Or if the "x+2" is in the denominator, then we have these steps:

[tex]f(x) = \frac{1}{x+2}\\\\f(3+h) = \frac{1}{3+h+2}\\\\f(3+h) = \frac{1}{h+5}\\\\[/tex]

Answer:

Angle K = 70degrees

Angle L = 68degrees

Step-by-step explanation:

Angle in a triangle add up to 180degrees

Figure out triangle the small triangle to the left side of the paper.

42+68+x=180

110+x=180

X=70

Angle K = 70degrees

Knowing that figure for angle L

70+42+x=180

112+x=180

X=68

Angle L = 68degrees

No solution :(

Step-by-step explanation:

-2(x-2)-4x=3(x+1)-9x  love these problems.

-2x+4-4x=3x+3-9x<-- I first multiplied the number outside of the parentheses to the numbers inside. Keep in mind that when a negative time a negative, it equals a positive, in the case of -2*-2.

-6x+4=-6x+3<-- I then combined like terms.

Right away I see that -6 and -6 would cancel out if i just added it to the other side. Thus this equation has no solution.. sorry.

Answer:

[tex]m=-\frac53; q=-2[/tex]

Step-by-step explanation:

Let's bring the line in the classical [tex]y=mx+q[/tex] form

[tex]3y= -5x-6\\y=-\frac53 x -2[/tex]

At this point we have the two values [tex]-\frac53[/tex] for the slope and [tex]2[/tex] for the intercept

In the intermediate steps, I rounded to 6 decimal places. The final answer is rounded to 3 decimal places (to the nearest thousandth).

Answer: She should have divided by 10 to find 10% of 60 because percent in latin means per centum which means for 100 or per each 100 and dividing by 10 means that the result times 10 equals the original number, so you would need to divide by 10.

Answer:

Y-intercept is at 1 and slope of the graph is 2

Step-by-step explanation:

When plotting this equation use the formula y=mx+b. The variable B is the y intercept its where you start your graph. The variable M is the slope and for that you use rise/run.

To graph 2 you would start at 1 because it's the int. And u would go up 2 and right 1 and just follow that pattern

A has 12 sides B is 5 sides

Answer:

A. 12 B. 5

Step-by-step explanation:

First we will do B.

Interior is 108 degrees Lets make an equation, 108={(n-2)*180}/n

Let's simplify

Now we have 108n=180n-360

180n-108n=360

Now we have 72n=360

n=5.

Now time for the first one.

150={(n-2)*180}/n

150=180n-360

180n-150n=360

30n=360
