51^7 -51^6 by 25
__*25

Answer:

.9

Step-by-step explanation:

Answer:

x-2y = 8

-2y = -x + 8

y = x/2 - 4

y intercept: (0, -4)

slope: 1/2

3x-2y = 12

-2y = -3x + 12

y = 3x/2 - 6

y intercept: (0, -6)

slope: 3/2

I assume I would graph with the following points (0,-4) and (4,0) for the second one I assumed I would graph the following points (0,-6) (6,0). I think I have confused the actual points in which I am to graph. Could you please tell me if I am graphing the correct points? I do not have the ISBN for this book becasue it is an online class. Thanks and have a great day!!

10y

x=2y

2y+y=4500

3y=4500

y=1500

x+1500=4500

x=4500−1500

x=3000

hence the 4500 is been divided into

two parts of 1500 and 3000.

Answer:

d

Step-by-step explanation:

Let m be the amount each mom can paint and d be the amount each daughter can paint.

On the first day, 8 mothers were painting so the mothers painted 8m square feet. 12 daughters also painted so the daughters painted 12d square feet. The total amount painted on the first day is then 8m+12d square feet. Since 220 square feet was painted on the first day, then 8m+12d=220.  Dividing both sides by 4 gives a simplified equation of 2m+3d=55.

On the second day, 6 mothers were painting so the mothers painted 6m square feet. 8 daughters also painted so the daughters painted 8d square feet. The total amount painted on the second day is then 6m+8d square feet. Since 152 square feet was painted on the second day, then 6m+8d=152

Multiply the first equation by -3 and then add it to the second equation to eliminate m and solve for d:

d=13

2m+3d=55

2m+3(13)=55

2m+39=55

2m=16

m=8

Therefore each mom painted 8 square feet and each daughter painted 13 square feet.

Answer:

Approx : 14.0294372515

Step-by-step explanation:

There are 2 congruent right triangles in this trapezoid. The hypotenuse and adjacent side lengths are 19 and 17 respectively. Using the Pythagorean Theorem, 19^2-17^2 is 72. The square root of 72 is approximately 8.48528137424. That is the length of the portions on the bottom that don't include the length x. 8.48528137424*2 is approximately 16.9705627485. 31-16.9705627485 gives you the length of the side x.

Answer:

y=4

Step-by-step explanation:

because this is an equilateral triangle, this means that all the size of the lengths is equal this means that,

2y+5 = 4y-3

(add 3 for both sides)

2y+8 = 4y

(subtract 2y for both sides)

8 = 2y

(divide by 2 for both sides)

4 = y

so,

y=4

Answer:

3x-5=7

3x=7+5

x=12/3

x = 4

Answer:

Step-by-step explanation:

3 times a number x: 3*x = 3x

5 subtracted from  3x = 3x - 5

Equation: 3x - 5 = 7

Solution:

    Add 5 to both sides

3x - 5 + 5 = 7 + 5

         3x = 12

Divide both sides by 3

        3x/3 = 12/3

x = 4

9514 1404 393

Answer:

  c = 4

Step-by-step explanation:

The equation has a constant on one side of the equal sign, and a variable term on the other side. Solve this by dividing both sides of the equation by the coefficient of the variable.

  [tex]2800=700c \qquad\text{given}\\\\ \dfrac{2800}{700}=\dfrac{700c}{700}\qquad\text{divide both sides by 700}\\\\4 = c \qquad\text{simplify}[/tex]

The value of c is 4.

Answer:

6:2

Step-by-step explanation:

X share from old ratio is 1/2

Y share from old ratio is 1/3

Z share from old ratio is 1/6

Now, we are told Y retires and that X and Z purchase his shares.

Thus;

Amount X took from Y = 1/2 × 1/3 = 1/6

Amount Z took from Y = 1/6 × 1/3 = 1/18

Thus, new share of X is now; 1/6 + 1/2 = 2/3

New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9

Ratio is now X:Z = 2/3 : 2/9 = 6:2

Answer:

x = 874

Step-by-step explanation

Set up your equation like this: Part/whole = percent/100

Assign the variable x to the unknown part of the equation and add in the known numbers:

So in this situation it would be: x/920 = 95/100

Solve for x:

100 times X = 920 times 95. (cross multiply)

That leaves you with 100x = 87,400

Divide both sides by 100:

x = 874

Answer:

The perimeter of JKL is 60 units.

Step-by-step explanation:

The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.

Answer:

that person is correct, each donut is only .25 cents because every 4 donuts are $1, multiply 4 by 3 and you get 12, 12=dozen. Since the total price is $3 it makes sense that each donut in .25 cents and every 4 donuts $1

HOPE THIS HELPS AND HOPE THIS MAKES SENSE!!!!!!!

If a dozen donuts cost $2.99 then the cost of one donut is approximately $0.25.

A division is a process of splitting a specific amount into equal parts.

Given that a dozen donuts cost $2.99.

We have to find the cost of 1 donut

As there are 12 donuts in a dozen, so to find the cost of one donut.

1 dozen donuts = 12 donuts.

One dozen donuts equal to twelve donuts.

To find the cost of 1 donut we need to divide the cost of a dozen by 12, because we are splitting the cost two point nine nine among twelve donuts.

$2.99 ÷ 12

Two point nine nine is divided with twelve we get zero point two five.

= $0.25

Therefore, the cost of one donut is approximately $0.25 to the nearest cent.

............ 1..1.1.1..1.1.

The graph of the function y = 15000 - 3000x represents linear regression.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have a finance person who used the function y = 15000 - 3000x to graph depreciation.

We have the following of depreciation -

y = 15000 - 3000x

The graph of the function y = 15000 - 3000x will have a negative slope of -3000. The line makes an obtuse angle with the +x - axis. This type of variation is called linear regression.

Therefore, the graph of the function y = 15000 - 3000x represents linear regression.

Answer:

Many options - 4/6 or 2/3 or 0.66

Step-by-step explanation:

When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !

Answer:You first would do 1/2 x 4/3 becuase when dividing numbers you use the keep change and flip method. So 1/2 you keep, you change the division sign into a multiplication sign and then 3/4 you flip into 4/3. After that you should have 1/2 x 4/3 and that gets you 4/6. So 4/6 would be your answer but simplified it would be 2/3. - Hope this helps!
