we can solve this by first combining like terms: our like terms in this equation are d and plain numbers

so, this means that we can combine the d's with the d's and the plain numbers with the plain numbers

so,

7d + 12 - 4d - 3 = 0

3d+ 9 = 0

next, we have to get our plain numbers on one side of the equal sign, and our numbers with the d's on the other side of the equal sign: we do this by doing the opposite of what the number is doing on the side it is on, since the 9 is being subtracted from the left hand side, we will subtract it from both sides:

3d = -9

next, we want to get rid of the 3 next to the d

to do this, we would divide the 3 on both sides since it is being multiplied to the d on the left hand side:

d = -3

this is our final answer: d = -3

All you have to do is add 31300000+23200000 which equals 54500000. Next subtract  54500000 from 193800000 which equals 139300000. So plant 2 is 139.3 million miles away from the sun

Let Planet 2 = X

Planet 1 = X + 31.3

Planet 3 = x +(31.3+23.2) = x + 54.5

Add the 3 distances together:

x + x +31.3 + x + 54.5 = 193.8

3x + 85.8 = 193.8

Subtract 85.8 from each side:

3x = 108

Divide both sides by 3:

x = 108 / 3

X = 36

Planet 2 = 36 million miles

Planet 1 = 36 + 31.3 = 67.3 million miles

Planet 3 = 36 + 54.5 = 90.5 million miles

36 + 67.3 + 90.5 = 193.8

Answer:

x = -[tex]\frac{17n+r}{n-34}[/tex]

Step-by-step explanation:

We have to solve the equation for the value of x.

n(17 + x) = 34x - r

17n + nx = 34x - r [By Distributive property ]

17n + nx - 17n = 34x - r - 17n [subtracting 17n from both the sides of the equation]

nx = 34x - r - 17n

nx - 34x = 34x - r - 17n - 34x [Subtracting 34x from both the sides of the equation]

x(n - 34) = -(r + 17n) [Division by (n - 34) on both the sides of the equation]  

x = -[tex](\frac{17n+r}{n-34})[/tex]

This is the solution for x in terms of constants n and r is x =  17n + r/34 - n

Solving for x in the equation n(17 + x) = 34x − r

To solve for x, we begin by isolating x on one side of the equation. Given the equation:

n(17 + x) = 34x - r

First, distribute n on the left-hand side:

17n + nx = 34x - r

Next, rearrange the equation to place all terms involving x on one side:

17n + r = 34x - nx

Factor out x on the right side:

17n + r = x(34 - n)

Solve for x by dividing both sides by (34 - n):

x =  17n + r/34 - n

This is the solution for x in terms of constants n and r.

The given angles are known as alternate interior angles.

For line L and M to be parallel, the two given angles must be the same.

Set them to equal each other and solve for X.

The answer is; 24/75 of the entire cake remained

If 2/5 of the initial cake was eaten, the 3/5 is what remained

MInu ate 1/3 of the 3/5 = 3/15

3/5 – 3/15 = 6/15 remained

Her brother ate; 1/5 of 6/15 = 6/75

6/15 – 6/75 = 24/75 remained

To convert the ratio 2.5 metres to 60 centimeters to the form 1:n we first change metres to centimeters, which gives 250 cm to 60 cm, then divide 250 by 60 to get n = 4.1667.

To find the value of n when the ratio is converted to the form 1:n, we need to express both measures in the same unit. We know that 1 metre is equivalent to 100 centimeters, so we can convert 2.5 metres to centimeters:

2.5 metres times 100 cm/metre = 250 cm

Now, we have the two measures in centimeters: 250 cm to 60 cm. Next, we divide both these numbers to find the ratio in the form 1:n.

250 cm / 60 cm = n

We simplify the ratio by dividing both numbers by 60 cm:

n = 250 cm / 60 cm = 4.1667

Therefore, the ratio of 2.5 metres to 60 centimeters expressed as 1:n is approximately 1:4.1667.

y + 4 = - 56(x - 8)

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 56 and (a, b) = (8, - 4)

y  + 4 = - 56( x - 8 ) ← in point-slope form

The x- intercept would be (3,0) or 3

The y-intercept would be (0,-4) or -4

The equation of the line that passes through the points (6,0) and (2,-7) is '7x - 4y = 42' when transformed into the standard form.

In mathematics, especially in linear algebra, the standard form of the line is a way of describing a specific line on the plane. We can get this by using two points through which the line passes. In this case, we have the points (6,0) and (2,-7).

First, we calculate the slope using the formula (y2 - y1) / (x2 - x1). Substituting our values, we have (-7 - 0) / (2 - 6) = -7 / -4 = 7/4. So, the slope is 7/4.

Next, we find the y-intercept (b) by substituting one of the points into the equation y = mx + b. Using the point (6,0), we get 0 = 7/4 * 6 + b. Solving for b, we find that b = -21/2.

The equation is then y = 7/4x - 21/2. To convert this to the standard form, we multiply all parts by 4 to remove the fraction. The equation then becomes 4y = 7x - 42. After arranging, we obtain our final equation: 7x - 4y = 42.

Final answer:

Alice hit 10 home runs and Peter hit 8 home runs that season. The width of the parallelogram is 16 meters and the length is 20 meters.

Explanation:

To solve this problem, we need to set up an equation. Let's say that Alice hit x home runs. Then, Peter hit twice the difference of home runs Alice hit and 6, or 2(x - 6). Together, they hit 18 home runs. Setting up the equation, we have x + 2(x - 6) = 18. Solving for x, we get 3x - 12 = 18, 3x = 30, and x = 10. So, Alice hit 10 home runs and Peter hit 2(10 - 6) = 8 home runs that season.

To find the length and width of a parallelogram, we need to use the information given in the problem. Let's say the width of the parallelogram is W. The length of the parallelogram is then 4 meters more than the width, or W + 4. The perimeter of a parallelogram is given by the formula 2(length + width), so we have 2(W + W + 4) = 72. Simplifying the equation, we get 4W + 8 = 72. Subtracting 8 from both sides, we get 4W = 64. Finally, dividing both sides by 4, we find that the width of the parallelogram is 16 meters and the length is 16 + 4 = 20 meters.

Answer:

1.178 x 10^35 Joule

Step-by-step explanation:

Energy produced by sun in one second = 3.8 x 10^27 J

Energy produced by sun in a year = Energy produced by sun in one second x number of seconds in one year

According to the question, the number of seconds in one year

                                                       = 31,000,000 seconds

Energy produced by the sun in one year = 3.8 x 10^27 x 31,000,000

                                                                    = 1.178 x 10^35 Joule

Thus, the energy produced by the sun in a year is 1.178 x 10^35 Joule.

Multiply both sides by 5
