Answer:

lbs of the cheaper chocolate => x = 6.6 pounds(Ibs)

lbs of the expensive chocolate => y = 4.5 pounds(Ibs)

Step-by-step explanation:

Let's the :

lbs of the cheaper chocolate => x

lbs of the expensive chocolate => y

You would like to have 11.1 lbs

Hence:

x + y => 11.1

x = 11.1 - y

You have one type of chocolate that sells for $6.00/lb and another type of chocolate that sells for $9.70/lb. of a chocolate mixture that sells for $7.50/lb.

Hence:

$6.00 × x + $9.70 × y = $7.50 × 11.1

6x + 9.7y = 83.25

Hence, we substitute 11.1 - y for x

6(11.1 - y) + 9.7y = 83.25

66.6 -6y + 9.7y = 83.25

-6y + 9.7y = 83.25 - 66.6

= 3.7y => 16.65

y = 16.65/3.7

y = 4.5 pounds

x = 11.1 - y

x = 11.1 - 4.5

x = 6.6 pounds

Hence:

You will need 4.5 lbs of the cheaper chocolate and 6.6 lbs of

Answer:

Step-by-step explanation:

divide 10 dollars by 6 avacados to get your unit rate, and then multiply that by 12 to get your cost.

10/6 is 3/2

3/2 times 6 is 18

so 18 dollars for 12 avacados

Answer: $20 if six avocados are $10 add 10+ 10= 20

Answer:

−12s2+11st−2t2

Step-by-step explanation:

Hope this helps!

Answer:

-12s - 2t

Step-by-step explanation:

First simplify the like terms.

-3s * 4s = -12s

(-12s + 2t)(-t)

Simplify the like terms again.

2t * (-t) = -2t

-12s - 2t.

Or

12s + 2t. (You can get this by multiplying the equation by -1)

The correct length of the court is 1126.8 inches.

You can find this value by taking 31.3 yards times 36 to equal 1126.8 inches.

Answer:

Step-by-step explanation:

y = ax + b

we will obtain a and b values, based in f(6)=8 and f(9)=3

f(6)=8 ⇒ 8 = a 6 + b ⇒ b = 8 - 6a

f(9)=3 ⇒ 3 = a 3 + b (sustituing b by above expression) ⇒ 3 = 3a + 8 - 6a

⇒ 3 = -3a + 8 ⇒ a = 5/3

b = 8 - 6 . 5/3 ⇒ b = 8 - 10 ⇒ b = -2

so, the linear function is:

f(x) = 5/3 x - 2

---- I'm sorry, f(9)=3 does not match /// there must be an error somewhere in my calculations /// hope can help. cheers!

Answer: x^2+2x-90

Answer:

[tex]\frac{3}{1}[/tex] or 3

Step-by-step explanation:

To find the slope find two coordinates and set up the equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. [tex]\frac{8_{}-2_ }{2-0_ }[/tex] you have to do subtraction first. 8-2 = 6 and 2-0 = 2

Now we have the equation [tex]\frac{6}{2}[/tex]

this can be simplified to  [tex]\frac{3}{1}[/tex]

Step-by-step explanation:

got it right on the test

Answer:

A theorem stating that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other sides. It is mathematically stated as c2 = a2 + b2, where c is the length of the hypotenuse and a and b the lengths of the other two sides.

Step-by-step explanation:

Answer:

a stands for one of the sides opposite the hypotenuse

Step-by-step explanation:

The Pythagoras theorem is

c^2 = a^2 + b^2

which states that the square of the hypotenuse is equal to the sum of the squares of the two opposite sides.

Step-by-step explanation:

Slope intercept form is y=mx+c, where m is the slope and c is the y-intercept

y = -1*x + 8

y=-x+8

Answer:

3.) Choice B

4.) Choice A

Step-by-step explanation:

Question #3:

You can find the equation by doing the y divided by the x and you'll get 4 every time so that's why it's Choice B.

Question #4:

A proportional equation is always a straight line that goes through the origin. So the answer is Choice A because it's the only one without a y-intercept because if the equation had a y-intercept it wouldn't go through the origin. For example, Choice B would go through (0,5) and Choice C would go through (0,-1) but we need it to go through (0,0).

Answer:

10a+6b

pls mark as brainliest.

Step-by-step explanation:

I think you mean 4a+6(a+b)?

We need to multiply out the the 6(a+b) first.

4a+6(a+b)

=> 4a+6a+6b

Then, we can add the like terms, which in this case are 4a and 6a:

=> 10a+6b

Step-by-step explanation:

Answer:

Step 2 : The error started at this step, when the student took 2x and 3x [Instead of 3x and 3x]. This is because 3x and 3x multiply to 9x^2 and sum up to 6x;whereas 2x and 3x multiply to 6x^2 and sum up to 5x.
