HELP PLEASE, I need help with number 3

Answer:

$425

Step-by-step explanation:

Let the dryer cost x

and the dish washer cost y

x+y=784-----------1

y=x-66-------------2

put the value of y=x-66 in 1

x+x-66=784

2x= 784+66

2x=850

x=850/2

x=425

Hence the dryer cost $425

Answer:

2. (1) [tex]30[/tex]

3. (1) [tex]y=\frac{1}{4}x[/tex]

4. a) [tex]y=x+6[/tex]   b) [tex]42[/tex]

Step-by-step explanation:

In a proportional relationship, y=2 when x=8, the following lines will show this relationship,

1.   y = 1/4x

2.  y = x - 6

4.  y =  1/2x - 2

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Given that,

The point,

x = 8 and  y = 2

We have to check all the given options,

1.   y = 1/4x

     y  = 1/4 × 8

     y  =  2

2.  y   = x - 6

         = 8 - 6

    y   =  2

3.  y   = 4x

         = 4 × 8

    y   = 32

4.  y   = 1/2x - 2

         = 1/2 × 8 - 2

         =  2

Hence, Option 1, 2, & 4 satisfies the given condition

Answer:

G n - 29 < 53

Step-by-step explanation:

Replace n with 81 so it becomes

81 - 29 < 53

If you solve, 81 - 29 would be 52

Then you have

52 < 53

This is true since 53 is greater than 52

Answer:

[tex]x=-3,13[/tex]

Step-by-step explanation:

Given: [tex]x^2-10x=39[/tex]

To find: solutions of the given equation

Solution:

[tex]x^2-10x=39\\x^2-10x-39=0[/tex]

Write [tex]-10=-13+3[/tex]

Therefore,

[tex]x^2-13x+3x-39=0\\x(x-13)+3(x-13)=0\\(x+3)(x-13)=0\\x=-3,13[/tex]

So, solutions of the given equation are [tex]-3[/tex] and [tex]13[/tex].

Answer:

After 15 days they'll both have $10

Explanation:

100 (Xavier's total)- 6x (6 dollars every day) = 160 (Zach's total amount) -10x (10 dollars every day)

[tex]100-6x=160-10x\\[/tex]

+10x on both sides

[tex]100+4x=160[/tex]

-100 on both sides

[tex]4x=60[/tex]

/4 on both sides

[tex]x=15[/tex]

Answer:

x= -35.153846

Step-by-step explanation:

360=200-5(x+37)

360=195(x+37)

360=195x+7215

360-7215=195x+7215-7215

-6855=195x

-6855/195=195x/195

-35.1538461538=x

Answer:

The cost of the house after one year = 84,750 rupees

Step-by-step explanation:

Explanation:-

Given that the cost of house = 13% in one year

Given that the house original price = 75000

We have to find that the house cost after one year

Solution:-

The cost of a house increase 13% per year

                        = 75000 X 0.13

                       = 9750

The total cost = 75000+9750

                      = 84,750 rupees

Final answer:-

The cost of the house after one year = 84,750 rupees

Answer:

The resulting price would be $100

Step-by-step explanation:

Subtract the percentage value from the original one

125 - 20%

125 - 125(0.2)

Answer:

B: 56 ounces no hate If I am wrong :)

The equation that is not equivalent to 2x + 14 = 4x - 6 is c) 2x - 4x = -20

To determine which equation is not equivalent, we need to simplify each option and see if it yields the same solution as the original equation.

Option c) simplifies to -2x = -20, which is different from the original equation. In the original equation, we have 2x + 14 = 4x - 6.

Therefore, the equation 2x - 4x = -20 is not equivalent to 2x + 14 = 4x - 6.

Answer:

To eliminate a variable in the system, we will have to subtract both expressions from each other

Step-by-step explanation:

Given the equations

5x+8y=-1

5x -8y=-7

To eliminate a variable in the system, we will have to subtract both expressions from each other

5x - 5x +8y-(-8y) = 1-(-7)

0 + 16y = 8

16y = 8

You can see that the variable x has been eliminated by simply subtracting both equations

y = 8/16

y = 1/2

Answer:

1250 students go to Excellent Elementary.

Step-by-step explanation:

Given that 4% of the students at Excellent Elementary are vegetarians, you can subtract 4% from 100% to find the percentage of students that are non-vegetarians:

100%-4%=96%

Now, since you know that 96% of the students are non-vegetarians and that they are 1200, you can use a rule of three to find the amount that represents 100% which would be the total amount of students that go to Excellent Elementary:

96%    →    1200

100%   →       x

x=(100*1200)/96

x=1250

According to this, the answer is that 1250 students go to Excellent Elementary.

Answer:

y + y+ y is 3y

Step-by-step explanation:

Answer:

here!

Step-by-step explanation:

so graphing lines are pretty hard but this one is fairly simple. here the slope formula format is y=mx+b

m being the slope

and b being the y-intercept

so as you can see your equation has no slope meaning your line is just going to be straight

and then if you take a look to find the only other thing your equation has in it is a 6 as the y-intercept meaning in order to graph this find where 6 is on the y-axis (the vertical line on the side) and draw a line going horizontal and put a dot or a point on (0,6) to mark that you have found the y-intercept and that this is the only known point on your line graph so far with the information given. i hope this makes sense, and have a great day!

Answer:

x= 20, y=95

Step-by-step explanation:

If you see the x angle, it makes 90 degree, and the straight line divides that angle into two. So by that;

x+25=45

x=20

Now if you add up all the angles on the straight line, it makes 180 degree,

by that,

x+25+y+40=180 (straight lines' angle=180 degree)

we now know that x=20, so now by adding that value, we get

20+25+y+40=180

y=180-40-25-20

y=180-85

y=95.

Hope This Helps.
