10x -20 plus 7x plus 4 equals 180 what is x

Answer:

i think c

Step-by-step explanation:

Answer:

y=2x+4

Step-by-step explanation:

First find out the slope, pick out 2 points. For ex. (-2,0) & (0,4)

Slope=4-0/0-(-2)

=4/2

=2

Y-intercept is 4.

Slope-Intercept form: y=mx+b

m is slope & b is y-intercept

y=2x+4

HOPE I helped!

Answer:

4<x<12

Step-by-step explanation:

8.0+4.0=12.0

8.0-4.0=4.0 or 4

The rules of triangles is that it must be less than the sum you had when you first added 8.0and 4.0 which was 12

So therefore , 4< x < 12

Answer:

x = 3.2

Step-by-step explanation:

Since, intercepts made by parallel lines on the transversals are in proportion.

[tex] \therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)[/tex]

AB = BC.... (given)

[tex] \implies \frac{AB}{BC} = 1..... (2)[/tex]

From equations (1) & (2)

[tex] 1 =\frac{EF}{FG}[/tex]

[tex] {FG}={EF}[/tex]

Therefore,

7x - 9 = 2x + 7

7x - 2x = 9 + 7

5x = 16

x = 16/5

x = 3.2

Answer:

3 terms

Step-by-step explanation:

5b+26t-72

Since none of the terms are like terms, we cannot combine them

There are 3 separate terms, 5b, 26t, 72

Answer:

It is closest to 1/2

Answer:

D. x ≈ 2.5

Step-by-step explanation:

Answer:

2.5x = 75

Step-by-step explanation:

Answer:

2.5

The lowest point on the graph, or the minimum is at f(x)= 2.5

The minimum value of the given periodic function is, 2.5

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

A periodic function,

Period  = 3π

The value of the function is in the range of (2.5, 4.5)

So,

Maximum value = 4.5

Minimum value  = 2.5

Thus, the minimum value is 2.5

Not choosing a presidential dollar can occur in 7 ways

Calculating Number of ways for choice

Given : Total 10 coins - 5 susan anthony dollars, 2 kennedy half dollars, 3 presidential dollars

To calculate : Number of ways through which non presidential dollar can be chosen

It can be calculated using Combination Choices

The dollar chosen is out of 7 dollars - 5 susan anthony dollars & 2 kennedy half dollars, ignoring & excluding the presidential dollars

So, number of ways = 7 c 1

= 7 ways

Answer:

The width of the garden is 22.12 m and its length is 27.12 m

Step-by-step explanation:

Equations

Let x = width of the garden

The length is 5 m longer than the wide, thus:

x + 5 = length of the garden

The area of the rectangular garden is

A=x(x+5)=600

Operating:

[tex]x^2+5x-600=0[/tex]

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Where a=1 b=5 c=-600:

[tex]\displaystyle x=\frac{-5\pm \sqrt{5^2-4(1)(-600)}}{2(1)}[/tex]

Operating:

[tex]\displaystyle x=\frac{-5\pm \sqrt{25+2400}}{2}[/tex]

[tex]\displaystyle x=\frac{-5\pm \sqrt{2425}}{2}[/tex]

There are two solutions:

x = 22.12

x = -27.12

The negative solution is not valid because x is the width of the garden, thus

x = 22.12 m

And

y = 22.12 + 5 = 27.12 m

The width of the garden is 22.12 m and its length is 27.12 m

Answer:

[tex]\angle L = 100^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle G = 5^{\circ}[/tex]

[tex]\angle H = 75^{\circ}[/tex]

[tex]\angle L = 100^{\circ}[/tex]

Required

Determine the measure of L after reflection across x-axis

When a shape is reflected across an axis, only the coordinates of the shapes is affected; the angles remain unaltered.

In other words, the measures of the angle will not change.

Hence:

[tex]\angle L = 100^{\circ}[/tex]

Answer:

7 ÷ 9 = 0.77777777777

= 0.778

The given fraction 7/9 as a decimal rounded to 3 decimal places is 0.778.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

To convert a fraction to a decimal, we need to divide the numerator by the denominator.

Here, we have:

7/9 = 0.777777...

7 divided by 9 gives us a repeating decimal of 0.7777777... and so on.

To round this to 3 decimal places, we need to look at the fourth decimal place. If it is 5 or greater, we round up the third decimal place. If it is less than 5, we simply leave the third decimal place as is.

In this case, the fourth decimal place is a 7, which means we need to round up the third decimal place.

Therefore, 7/9 as a decimal rounded to 3 decimal places is 0.778.

Answer:

33.3m^2

Step-by-step explanation:

If Jessica waxes 20 m^2 of the floor in 3/5 of an hour, then;

20m^2 = 3/5 hr

To get the area that she waxes in an hour

x = 1 hr

Divide both expression

20/x = 3/5

3x = 20 * 5

3x = 100

x =100/3

x = 33.3m^2

Hence she can wax 33.3m^2 in an hour

Answer:

Number of wooden cubes in the box = 240

Step-by-step explanation:

A toy company uses the Box shown below to package wooden cubes each wooden Cube has a volume of 1/8 cubic feet in total how many wooden cubes will fit in the Box

Volume of the box = length × width × height

= 5 ft × 3 ft × 2 ft

= 30 ft³

Each wooden cube has a volume of 1/8 cubic foot

how many wooden cubes will fit in the box?

Number of wooden cubes in the box = Volume of the box ÷ volume of the wooden cube

= 30 ft³ ÷ 1/8 ft³

= 30 × 8/1

= 240

Number of wooden cubes in the box = 240
