A) Chanece wants to bake
6 cakes for the school bake
sale. The recipe says each
cake needs 2/4 cup of
sugar. How much sugar
will Chanece need for
her 6 cakes?

Answer: 13x -8y

Hey there!

To get started we need to figure out what the equation is by remembering the sum is addition.

6x-y + 7x-7y

Then we need to combine like terms

(6x+7x) (-7y-y)

to get...

13x-8y

Answer:

Step-by-step explanation:

Answer:

The answer is~ no solution

Step-by-step explanation:

its no solution because

3x−3(x+1)=3

Step 1: Simplify both sides of the equation.

3x−3(x+1)=3

3x+(−3)(x)+(−3)(1)=3(Distribute)

3x+−3x+−3=3

(3x+−3x)+(−3)=3(Combine Like Terms)

−3=3

−3=3

Step 2: Add 3 to both sides.

−3+3=3+3

0=6

Step-by-step explanation:

Answer:

angle Y is 29 degrees

angle X is 120 degrees

Step-by-step explanation:

Well, if the triangle is an equilateral, then all the angles are equal to

60 degrees

that means the the angle at the top point is 60+31 = 91 degrees

the right point is 60 degrees

every triangle has 180 degrees total

180 - (91+60) = 29 degrees

NOW FORGET ABOUT THE EQUILATERAL FOR A BIT

180 = 31+x+29

simplify

180 = 60+x

subtract 60 from both sides

120 = x

Step-by-step explanation:

The given statement is the scale factor:

  [tex]\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}[/tex]

This can be rearranged to the formula ...

  [tex]\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}[/tex]

Filling in the given scale distances, you find the actual distances to be ...

  [tex]\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\[/tex]

Step-by-step explanation:

This is simplified. For  the question 4/10 .

Answer:

t = 8, t = 4

Step-by-step explanation:

-t² + 12t = 32

-t² + 12t - 32 = 0 (Subtracted 32 on both sides.)

t² - 12t + 32 = 0 (Divided by -1 on both sides.)

(t - 8)(t - 4) = 0 (Factor.)

t - 8 = 0   t - 4 = 0

t = 8   t = 4

Answer:

The dimensions that result in the maximum area are therefore;

Width = 3.5

Height = 3.5

Step-by-step explanation:

The given parameters are;

The area of the rectangle, y = x × h

Where;

x = The width of the rectangle

h = The height of the rectangle

By examination, we have;

x + h = 7

Therefore, x = 7 - h

Which gives;

y = x × (x - 7) = x² - 7·x

y = x² - 7·x

At x = 0, y = 0

At x = 7, y = 0

However, at x = 1, y = -6

Therefore, the function should be, y = -(x² - 7·x)

The maximum occurs where dy/dx = 0, which gives;

dy/dx = d-(x² - 7·x)/dx = 0

dy/dx = 2·x - 7 = 0

2·x - 7 = 0

x = 7/2 = 3.5

On second derivative, we have;

d²y/dx² = 2, which gives a local minimum

x = 3.5 at maximum height

Which give, the maximum height, [tex]y_{max}[/tex] = -(x² - 7·x) at x = 3.5

∴ [tex]y_{max}[/tex] = -(3.5² - 7×3.5) = 12.25

The maximum height = 12.25

The dimensions that result in the maximum area are therefore;

Width, x = 3.5

Height, h = 7 - x = 7 - 3.5 = 3.5

Height, h = 3.5.

Answer:

2.5 or 10/4

Step-by-step explanation:

2÷4/5  

Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,

2/1÷4/5

But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)

2/1×5/4

And tadaa! you get your answer

10/4

You can also simplify it!

5/2

Answer:

Step-by-step explanation:

 x - 3y = 5

2x +  y = 10  multiply by 3 to eliminate y and solve for x

 x - 3y = 5

6x + 3y = 30  then add

7x          = 35

simplify:

x = 35 / 7

x = 5  

substitute x = 5 back into the eq.2

 2x +  y = 10

2(5) +  y = 10

           y = 10 - 10

           y = 0

therefore the answer is ( 5, 0 )

Step-by-step explanation:

Answer:

60% of the employees are men.

Then the 40% left must be women.

4 of them are selected.

a)  What is the random variable we can consider here?

A random variable is a variable that can have different outcomes or values, in other words, it is a stochastic variable.

We have a selection of 4 employees at random, then we can define the variable X, that represents (for each employee) the possibility of being man or woman.

b) Probability of 3 men and 1 woman.

Suppose that the selection is in the order:

man-man-man-woman.

We have:

0.6 tree times.

0.4 one time.

P = 0.6^3*0.4

But this is for the case where the woman is in the last selection, it can be in the first, second and third, then we have 4 permutations, the actual probability is:

P = 4*( 0.6^3*0.4) = 0.3456.

c) If now we have tat 75% are men, then 25% are women.

Now we can do the same as before, but now the probability for a man is 0.75 and for a woman is 0.25, then the previous equation is now:

P = 4*(0.75^3*0.25) = 0.421875

(a) The random variable will be "Men percentage".

(b) The probability of finding 3 men and one woman be "0.3456".

(c) The probability be "0.4219".

(a) A random variable represents a variable which might have several occurrences as well as quantities; it is indeed a stochastic quantity.

If we choose four workers at random, users may create the variable X, which reflects the potential of someone being a male or even a woman.

(b) The probability be:

→ P(3 men and women) = [tex]4C_3[/tex] (0.6)³ (1 - 0.6)¹

                                       = 0.3456

(c) The probability be:

→ P(3 men and women) = [tex]4C_3[/tex] (0.75)³ (1 - 0.75)¹

                                       = 0.4219

Thus the response above is correct.

Answer:

y = x - 8

Step-by-step explanation:

In order to solve this, we need to use point-slope form.:

y - y1 = m(x - x1)

Substitute the numbers into the equation:

y - (-8) = 1(x - 0)

y + 8 = x

y = x - 8

Answer:

The answer is C:All real solutions

Step-by-step explanation:

here are the steps in case u need them :)

Step 1: Simplify both sides of the equation.

−2(x+3)=−2x−6

(−2)(x)+(−2)(3)=−2x+−6(Distribute)

−2x+−6=−2x+−6

−2x−6=−2x−6

Step 2: Add 2x to both sides.

−2x−6+2x=−2x−6+2x

−6=−6

Step 3: Add 6 to both sides.

−6+6=−6+6

0=0

Answer:

C: All real numbers.

Step-by-step explanation:

-2 ( x + 3 ) = -2x -6

-2 times x, -2 times 3

-2x -6 = -2x -6

Add 6

-2x -6 +6 = -2x -6 +6

-2x = -2x

Answer:

8

Step-by-step explanation:

Since there are two fractions, it is easiest to cross multiply the fractions before doing anything else. Basically:

10/15 = d/12  becomes 120 = 15d.

then you just divide 15 to both sides to get your answer:

d = 120/15, which is the equivalent of d = 8.

Answer:

m = rise / run = 1/7

Step-by-step explanation:

Recall that the slope of a line is m = rise / run.

Here we look at x first (to calculate the run):  x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.  

Now look at how y behaves (find the rise):  y begins at 0 and ends at 1. Thus, the rise is 1.

Therefore the slope of the line connecting the two poings given is

m = rise / run = 1/7
