Answer:

180-[tex]x^{2}[/tex]

Step-by-step explanation:

Answer:

1) 1.25*3

2) 1.25 multiplied by 3

3) 3.75

Step-by-step explanation:

Answer:

#3- x=2.73

#4- x=8

Step-by-step explanation:

Answer: X = 3 / X = 8

Step-by-step explanation:

3. (Angles add up to 180)

30x + 4 + 86 = 180

30x + 90 = 180

subtract 90 from both sides

30x = 90

Now divide by 30

x = 3

Check your work ( input 3 to the equation)

30(3) + 4 + 84

90+ 90 = 180  it works :)  

4. (Angles are adjacent to each other so there equal)

10x - 3 = 77

add 3 to both sides

10x = 80

divide it by 10

x = 8

Check your work ( input 8 to the equation )

10(8) -3 = 77

80 - 3 = 77

77 = 77

Step-by-step explanation:

c)16 km

=========================================================

Work Shown:

Convert each mixed number to an improper fraction.

3 & 1/9 = 3 + 1/9

3 & 1/9 = 3*(9/9) + 1/9

3 & 1/9 = 27/9 + 1/9

3 & 1/9 = (27+1)/9

3 & 1/9 = 28/9

The car's average speed is 28/9 km per hour.

5 & 1/7 = 5 + 1/7

5 & 1/7 = 5*(7/7) + 1/7

5 & 1/7 = 35/7 + 1/7

5 & 1/7 = (35+1)/7

5 & 1/7 = 36/7

The time the car travels is 36/7 hours.

----------------------

We did the conversions so we can multiply the values easier.

Distance = Rate*Time

Distance = (28/9)*(36/7)

Distance = (28*36)/(9*7)

Distance = (4*7*9*4)/(9*7)

Distance = (4*4)/(1)

Distance = 16 kilometers

Answer:

13

Step-by-step explanation:

If ABC is equilaterteral then all the angles must be equal and 60°

8x - 44 = 60 add 44 to both sides

8x = 104 divide both sides by 8

x = 13

Answer:

is the graph of y=-2x-1

The equation of line which is parallel to given line is , [tex]y=-\frac{1}{2}x-1[/tex]

Option H is correct.

Given line is passes through points [tex](-4,6)[/tex] and [tex](4,2)[/tex]

Slope of given line is,

                  [tex]Slope=\frac{2-6}{4+4}=-\frac{1}{2}[/tex]

Since, all parallel lines have the same slope.

So that, slope of line parallel to given line is also equal to [tex]-\frac{1}{2}[/tex]

Equation of required is,

               [tex]y=-\frac{1}{2}x+c[/tex]

Since, line passes through point [tex](0,-1)[/tex]

So that,  [tex]c=-1[/tex]

Step-by-step explanation:

15   x  5           75

----      =          -------

20  x  5           100

Cent means 100, so percent literally means per 100 like in century or centennial. So, I put it into a fraction over 100. Now it is 75 per 100. If you remember, per 100 is percent, it means the answer id 75 percent. You can also write it as 75%.

Step-by-step explanation:

A triangle's total degrees is 180. You add the two angles they give you and then subtract the sum from 180. In number 9, the answer is 61. 47+72=119, 180-119= 61.

Answer:

Step-by-step explanation:

From the figure, we have

The coordinates of the point F are: (-4,1).

The coordinates of the point G are: (0,-2)

The coordinates of the point J are: (0,4) and

The coordinates of the point H are: (-4,-2).

Now, the slope of the line FG is :

Answer:

8.06

Step-by-step explanation:

d = √( [tex]x_{1}[/tex] - [tex]x_{2[/tex] ) + ( [tex]y_{1}[/tex] - [tex]y_{2}[/tex] )

d = √ ( 3 - (-1) )² + ( -4 - 3 )²

d = √(4)² + (-7)²

d = √16 + 49

d = √65

d = 8.06

Answer:

The slope is 4.

Step-by-step explanation:

We are given that f(0)=-5 and f(4)=11.

This means that we have the two points (0, -5) and (4, 11).

So, we can use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, -5) be (x₁, y₁) and let (4, 11) be (x₂, y₂). Substitute appropriately:

[tex]m=\frac{11-(-5)}{4-0}[/tex]

Evaluate:

[tex]m=\frac{16}{4}=4[/tex]

Hence, the slope of the line given f(0)=-5 and f(4)=11 is 4.

Answer:

Step-by-step explanation:

For 7x = 49 you need to divide 7 to both sides

For -4x=-40 you need to divide -4 to both sides

For x/2 = 6 you need to multiply 2/1 to both sides

For x/9 =- 2 you need to multiply 9/1 to both sides

Step-by-step explanation:

Complete question

Consider these numbers, ordered from least to greatest. Negative 1.8, negative 1 and one-fourth, negative 0.2, blank, one-half, 90 percent A number line going from negative 2 to positive 1. Which values could correctly fill in the blank? Select all that apply. 10% 1 -0.1 -1 One-fourth

step-by-step explanation

On the number line, numbers increase from left to right.

The blank is between -0.2 and 1/2.

Only numbers greater than -0.2 and less than 1/2 can fill the blank.

Range = -0.2<x<1/2

From the values given,

1) 10% = 10/100 = 1/10 = 0.1

-0.2<0.1<1/2

2) -0.2<1

But, 1>1/2

3) -0.2<-0.1<1/2

4) -0.2>-1

5) -0.2<1/4<1/2

Therefore, only 10%, -0.1, and 1/4 can fill in the blank correctly because they satisfy the range -0.2<x<1/2
