3/5 (15x - 20) = -6x + 4(x - 6)

Answer:

Number of chicken sandwiches = 150

Number of turkey sandwiches = 150

Number of roast beef sandwiches= 100

Step-by-step explanation:

We are told the school cafeteriat makes and sells 3 different types of sandwiches which are; chicken, turkey and roast beef.

Let chicken be x, turkey be y and roast beef be z.

We are told they make 400 sandwiches in total.

Thus;

x + y + z = 400

However, we are told that the cafeteria makes same number of chicken and turkey sandwiches.

Thus, x = y

Thus;

Total is now;

x + x + z = 400

2x + z = 400 - - - (eq 1)

Now,we are told that chicken, turkey and roast beef sandwiches are sold for $3, $3.5 and $4 respectively. Also that the total amount realized from sales is $1375.

Thus;

3x + 3.5y + 4z = 1375

Since x = y. Thus;

3x + 3.5x + 4z = 1375

6.5x + 4z = 1375 - - - (eq 2)

Let's make z the subject in eq 1.

Thus;

z = 400 - 2x - - - (eq 3)

Putting 400 - 2x for z in eq(2) gives us;

6.5x + 4(400 - 2x) = 1375

6.5x + 1600 - 8x = 1375

1600 - 1375 = 8x - 6.5x

225 = 1.5x

x = 225/1.5

x = 150

Putting 150 for x in eq 3 gives;

z = 400 - 2(150)

z = 400 - 300

z = 100

Since x = y. Then y = 150

Answer:

Step-by-step explanation:

(-6)-(-8)=2.

7-14=-7

2/-7=-0.28

Answer:

The width is 3 inches.

Step-by-step explanation:

First, let's identify our variables.

L=Length

W=Width

P=Perimeter

P=2W+2L

We know that L=W+6

We can substitute L for W+6, and we can substitute P for 8W, which gives us the equation:

8W=2W+2(w+6)

If you go through all the steps to isolate the variable W, you'll end up with W=3

Answer:

13. -200, balance on car loans

14. 8, monthly payments

15. linear eqn, y=ax+b

16.values of y will decrease.(although i think the graph will remain linear)

17. as the monthly payment decrease so does the balance on car loan decrease.

Answer:

D) (-5, - 7)

Step-by-step explanation:

Because both lines intersect, they must share a point (have same x and y coordinates).

[tex]2x + 3 = - 4x - 27[/tex]

[tex]2x = - 4x - 30[/tex]

[tex]6x = - 30[/tex]

[tex]x = - 5[/tex]

Substite x for - 5 in any of the equations to find the y coordinate.

[tex]y = 2( - 5) + 3 [/tex]

[tex]y = - 10 + 3[/tex]

[tex]y = - 7[/tex]

The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

Answer:

237.5

Step-by-step explanation:

Since the bucket loses 0.3 oz of water per second, and 20 secs passed, you would have to multiply 0.3 and 20 to find out how much water leaked. And 0.3x20=6, so then, we would have to subtract 234.5 and 6 to find out how much water there is left in the bucket. 234.5-6=237.5

So 237.5 is your answer

Answer:

y=12

Step-by-step explanation:

8=-4*3 +b

8=-12=b

20=b

y=-4x=20

-4*2 is -8+20 is 12

(2,12)

Remember from now on ;

If the value of f(x) is asked, we put what thing written in parentheses inside the function instead of x. It doesn't different what is written, we just have to replace it with x.

Got it ?

Now Let's do it .....

[tex]f( x) = 8 {x}^{2} - 14x - 10 [/tex]

[tex]f( - 2) = 8({ - 2})^{2} - 14( - 2) - 10 \\ [/tex]

[tex]f( - 2) = 8 \times 4 + 28 - 10[/tex]

[tex]f( - 2) = 32 + 28 - 10[/tex]

[tex]f( - 2) = 60 - 10[/tex]

[tex]f( - 2) = 50[/tex]

Answer:

4/3 as an improper fraction or 1 1/3 as a mixed number

Step-by-step explanation:

4 divided by 3= 4/3 =1 1/3

The 4 divided by 3 answers as a fraction is 4/3 and 4 is in the numerator and 3 is in the denominator.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

The expression in words is  4 divided by 3 answers as a fraction.

As we know, the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

Here we have to division:

= 4 ÷ 3

or

= 4/3

4 is in the numerator and 3 is in the denominator.

Thus, the 4 divided by 3 answers as a fraction is 4/3 and 4 is in the numerator and 3 is in the denominator.

Answer:

Step-by-step explanation:

Answer:

The answer is C. (−94⋅32)⋅(63⋅57)=−94⋅(32⋅63)⋅57

Step-by-step explanation:

I took the K12 test

Answer:

Step-by-step explanation:

Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k

For the x coordinates:

C' = kC

x' = kx

-2 = k(-6)

-2 = -6k

Divide both sides by -6

k = -2/-6

k = 1/3

For the y-coordinates:

y' = ky

3 = 9k

Divide both sides by 9:

3/9 = 9k/9

1/3 = k

k = 1/3

Hence the scale factor of the dilation is 1/3

Answer:

The scale factor from C' to C is

3

But the scale factor from C to C' (the one you may have asked for in the question) is

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

Step-by-step explanation:

What we already know is that we have line segments C and C' and we know their lengths.

C = (-6, 9)

C' = (-2, 3)

So the scale factor from C' to C can be easily known if we simply use the rules of division

-6 ÷ -2

and

9 ÷ 3

They both are equal to the outcome, 3.

So we now know that the scale factor from C' to C is 3.

But what about C to C'??

Yes we still have to do division, BUT (you may have guessed it already but), we must switch the positions that the numbers for dividend and divisor were.

-2 ÷ -6 =

0.33333333...  or  [tex]\frac{1}{3}[/tex]

3 ÷ 9 =

0.33333333...  or  [tex]\frac{1}{3}[/tex]

So we can decisively conclude that the scale factor of C to C' is [tex]\frac{1}{3}[/tex]

Answer:

1. [A] More than 205

2. [B] less than 10

3. [B] less than 0.2

Step-by-step explanation:

1. The value of 25 · (8.5) is:

a. More than 205

b. Less than 205

Solve:

25 · (8.5) = 212.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2. The value of (9.93) · (0.984) is:

a. More than 10

b. Less than 10

(9.93) · (0.984) = 9.77112

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3. The value of (0.24) · (0.67) is:

a. More than 0.2

b. Less than 0.2

(0.24) · (0.67) = 0.1608

The answer is 5 because you can fit 365 into 15 24 times and then that would equal 360 and then you have 5 left over.

15x24=360             365

                              -  360

                                 ____

                                   5

Answer:

C

Step-by-step explanation:

10 can go into 365 10 times leaving 5 left over.

Answer:

Step-by-step explanation:

AC = 8 + 15 = 23

C to the tangent point of BC = 15 (tangents are equal when they come from the same point.

B to the tangent point of BC  = 12 (same reason).

BC = 15 + 12 = 27

By a similar argument BA = 12 + 8 = 20

So add them together. 20 + 27 + 23 = 70 I think.

You are absolutely right. Or we both are wrong.
