Answer:

95 balloons

Step-by-step explanation:

red = 40

green- 40x(3/5) = 24

yellow- 24÷(2/3) =36

36× (1/36) = 1. 1 yellow balloon popped

24× (1×12) = 2. 2 green balloons popped

40×(1/20) =2. 2 red balloons popped

40+24+36= 100

2+2+1=5

100-5 = 95 balloons left for decorations

I'm pretty sure the answer to y=−x. Write equation for (8,2) is y=x-6. The opposite of the x is -8, hence, (-8,2) is y=-x-6 is the answer

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

What is Equation of line?

The equation of the line in slope-intercept form is expressed as:

y - y₁ = m(x - x₁)

where: m is the slope.

and (x₁, y₁) is the point on the line.

1. Given that;

Equation of the line as y = -x

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - (-8) )

y - 2 = x + 8

y = x + 8 + 2

y = x + 10

Hence, The equation of the line which is parallel and goes through the point (-8, 2) is,

⇒ y = x + 10

2.  Given that;

Equation of the line as y = -x

Point as (8, 2)

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - 8 )

y - 2 = x - 8

y = x - 8 + 2

y = x - 6

Hence, The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

Thus,

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

From the question;

1) Ruby will save $95 after ten weeks

2) The equation for ww weeks is; S = $25 + ($7 x ww)

Total savings after 10 weeks:

Ruby saves $7 per week from her after school job, and she already has $25, so her total savings after 10 weeks can be calculated as follows:

Total savings = Initial savings + (Weekly savings x Number of weeks)

Total savings = $25 + ($7 x 10)

Total savings = $25 + $70

Total savings = $95

So, Ruby would have a total of $95 after 10 weeks of saving.

Expression for the amount of money Ruby would have saved in ww weeks:

Let "S" represent the total savings after ww weeks.

Expression: S = $25 + ($7 x ww)

Answer:

x+x refers to x being added

For Eg:

5+5=10

x+x refers to x being multiplied

For Eg:

5*5 = 25

So you can see that the product is greater than sum

Not always though,

For Example take 2+2=4

and 2*2 = 4

Interestingly 2^2 is also equal to 4

The division property states that when we have an equation in the form [tex]ax=b[/tex], then [tex]x=b/a[/tex](i.e. we "divide" by [tex]a[/tex] on both sides).

So, Mark was supposed to get [tex]x=9/23[/tex], which is not equal to [tex]6[/tex].

So, Mark solved it [tex]\boxed{wrong}[/tex]

No, Mark solve the equation correctly.

because, Mark was supposed to get x = 27/2 , which is not equal to x= 6.

The division property of equality applicable.

The division property of equality is a property that tells us if we divide one side of an equation by a number, we must also divide the other side by the same number so that our equation stays the same. The formula for this property is if a = b, then a / c = b / c.

We have the following information available from the question is:

Answer:

the question is what problem

Step-by-step explanation:

Answer:

Solution by graphing: (5, 2)

Step-by-step explanation:

y = x - 3  

y = - 3/5x + 5

To solve systems of linear equations graphically, you'll have graph each equation using 2 pairs of points.  

A great starting point is always using its intercepts:

y = x - 3

where the y-intercept is (0, -3).

To find its x-intercept, set y = 0 and solve for the value of x:

y = x - 3

0 = x - 3

Add 3 to both sides:

0 + 3 = x - 3 + 3

3 = x

Therefore, the x-intercept = (3, 0).

y = - 3/5x + 5

where the y-intercept is (0, 5).

Next, you could find a value of x that easily cancels out the fraction given by the slope (m) = -3/5. An input value of x = 5 cancels out the denominator of the slope:

y = - 3/5x + 5

y = - 3/5(5) + 5

y = -3 + 5

y = 2

Therefore, the other point that you could use to plot on the graph is (5, 2).

For y = x - 3, we'll use the line's intercepts: (0, -3) and (3, 0).  

For  y = - 3/5x + 5, we'll use (0, 5) and (5, 2).  

Plotting these points on the graph will give us a solution of (5, 2), as it is the point where both lines intersect. Attached is a screenshot of the graphed lines.
