Answer:

9c - 3d

Step-by-step explanation:

5c-6d+4c+3d

Gather the like terms,

5c + 4c - 6d + 3d

9c - 3d

Hope it helps!<3

Simplifying

5c + -6d + 4c + 3d = 0

Reorder the terms:

5c + 4c + -6d + 3d = 0

Combine like terms: 5c + 4c = 9c

9c + -6d + 3d = 0

Combine like terms: -6d + 3d = -3d

9c + -3d = 0

Solving

9c + -3d = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '3d' to each side of the equation.

9c + -3d + 3d = 0 + 3d

Combine like terms: -3d + 3d = 0

9c + 0 = 0 + 3d

9c = 0 + 3d

Remove the zero:

9c = 3d

Your answer: 9c=3d

Answer:51.14

Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360

2x+5+5x-3=360

7x+2=360

7x=358

x=51.14

The measure of each angle is 31, 31 and vertex angle is 118.

If a triangle side is created, the outside angle that results is equal to the product of the two opposite internal angles.

Given:

Base angle = (2x+ 5) and Vertex = (5x- 3)

So, We know that the exterior angle is equal to sum of opposite interior angle

5x- 3 = 2x+ 5 + 2x + 5

5x - 3= 4x + 10

x= 13

Thus, Each angle measure 2(13)+ 5 = 31 and

third angle = 180 - (5x- 3) = 180- 62 = 118

Hence, the measure of each angle is 31, 31 and vertex angle is 118.

The solution to the system of inequalities y < 2x - 8 and y > -1/2x - 3 is (2, -4)

The system of inequalities is given as

y < 2x - 8

y > -1/2x - 3

Next, we plot the system of inequalities on a graph (see attachment)

From the attached graph, we have both lines of the graph intersect at (2, -4)

Hence, the solution to the system of inequalities y < 2x - 8 and y > -1/2x - 3 is (2, -4)

The required intercepts of the given equation is x = -2 and y = -2.5.

Distance from the origin to points where a line crosses an axis is known as the x-intercept and the y-intercept, respectively.

Here,
Given the equation of the line,
-5x-4y=10

Now, in order to determine the intercepts of the equation put x = 0 and y = 0 individually,

So,
x = 0
-4y = 10
y = -2.5

Now, put y = 0
-5x = 10
x = -2

Thus, the required intercepts of the given equation is x = -2 and y = -2.5.

The heaviest package is 2 (7/8) heavier than the lightest package.

A dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.

We have,

From the given dot plot,

we see that there is one gift that weighs 1/8 pounds which is the lightest package.

The weight of the lightest package is:

= 1/8 pounds

we see that there are 4 gifts that weigh 6/8 pounds for each gift which is the heaviest package.

The weight of the heaviest package is:

= 4 x 6/8

= 3 pounds

The difference between the weight of the heaviest package with the lightest package is:

= 3 - 1/8

= (24 - 1) / 8

= 23/8

= 2 (7 / 8) pounds

Thus the heaviest package is 2 (7/8) heavier than the lightest package.

Answer:

-3.6

Step-by-step explanation:

The general equation of a straight line formula is represented as y = mx + c, where m is the gradient or slope of the line and c is called the intercept on the y-axis.

The equation of the line in the question above is y= −3.6x + 59 ,

Therefore comparing both equations together,

y = mx + c = y = −3.6x + 59

m = -3.6

Therefore, the slope of the equation represent in this scenario is -3.6
