Answer:

91

Step-by-step explanation:

7(7) - 9(-2)+2(7)

=142+49

=91

Answer:

81

Step-by-step explanation:

Simplify it first:

7r-9s+2r = 7(7)-9(-2)+2(7) = 49-(-18)+14

(Since you have 49-(-18) it automatically becomes addition/a positive.)

So you have 49+18=14 which equals 81.

Answer:

2

Step-by-step explanation:

A commutative function means that when you insert one function in space of x in the other function, they will equal x. The equation is f(g(x)) = g(f(x)) = x

So, 2([tex]\frac{x+1}{a}[/tex]) - 1 = [tex]\frac{(2x-1)+1}{a}[/tex]

If you multiply both sides by a, you get   2a([tex]\frac{x+1}{a}[/tex]) - a = (2x-1)+1

Simplify it                                                   2a([tex]\frac{x+1}{a}[/tex]) - a = 2x

Add a to both sides                                    2a([tex]\frac{x+1}{a}[/tex])  = 2x +a

The two as on the left cancel out                   2(x+1)=2x+a

Distribute the 2                                               2x+2=2x+a

Then subtract 2x from both sides                        2 = a

Therefore, a = 2

Answer:2

Step-by-step explanation:

Answer:

The correct options are;

A. Construct a perpendicular bisector of the diameter AB

D. Use the compass to draw a circle centered at point C

E. Use the compass to draw two arcs of the same radius centered at point C

F. Use the straightedge to draw diameter AB of the circle

G. Use the straightedge to draw lines connecting the endpoints of the two diameters

Step-by-step explanation:

To draw an inscribed square of a circle, the circle is first constructed. The diameter of the circle is drawn with a straight edge to find the first two vertices of the intended inscribed square. The perpendicular bisector of the diameter is then drawn intersecting the circumference to provide the other two vertices of the square.

The straightedge is then used to draw lines that connect the endpoints of the two diameters to form the inscribed square of the circle.

The expression that describes the width of Kevin’s yard is (3g + 12) feet

Step-by-step explanation:

This is an expression problem.

From the question, we are made to know that the width of the yard is 3 times the width of the garage increased by 12 feet.

Now, we are told that the width of the garage is g feet and we want to find the width of the yard.

The width of the yard will be g feet * 3 + 12

Mathematically that would be 3g + 12 feet

Answer:

7/15

Step-by-step explanation:

For me, it is easier to take the 3/5 and put it in decimal form which is .6 and add the 5 to it, making 5.6, and then in a calculator put in 5.6 divided by 12 and you should get a big decimal that's pretty big but if you have a graphing calculator and convert that to a fraction and you should get 7/15, This is a pretty lazy way of me doing it but that's how I did it.

Answer:

213 degrees

Step-by-step explanation:

A quadrilateral has an internal measurement of angles of 360 degrees.  Given that we have 3 measures of the angles, we simply need to find the 4th.  This can be accomplished with the following equation:

x + 52 + 54 + 41 = 360

x + 52 + 95 = 360

x + 147 = 360

x = 213

Hence, the measure of the final angle is 213 degrees.

Cheers.

Answer: A. 11 . 38 + 4 . 03

                B. 10 + 5 . 41

                 D. 9 . 2 + 6 . 21

Step-by-step explanation:

Step 1

Compute the sum of the given options

a)  11 . 38 + 4 . 03 = 15.41

b) 10 + 5 . 41= 15.41

c) 12 . 38 + 2 . 93= 15.31

d) 9 . 2 + 6 . 21 =15.41

e) 7 . 54 + 6 . 87=14.41

Step 2

Eliminate the expressions that do not give a sum of 15.41 , we have

a)  11 . 38 + 4 . 03 = 15.41

b) 10 + 5 . 41= 15.41

d) 9 . 2 + 6 . 21 =15.41

Therefore, the expressions with sum of 15.41  are A, B  and D

Step-by-step explanation:

All you must do is find the correct values in the graph.

The graph which is generated by the table of values x -5,-3,-1,4 and y=2,4,1,0 is on coordinate plane points are at (-5,2) ,(-3,4) ,(-1,1) ,(4,0).

A function is a relationship between two or more variables having each value of x corresponding to y values. Values of x are known as domain and values of y are known as codomain.

We have been given the following table as under:  

  x                           y

 -5                          -3

 -3                           4

 -1                           1

   4                           0

We have to plot the points -5 ,-3,-1,4 on x axis and corresponding-3,4,1,0 on y-axis.

Hence the graph of given table of values is that on coordinate plane points are at (-5,2) (-3,4)(-1,1)(4,0).

Answer:

x = 7/15

Step-by-step explanation:

x + 6/4 + x - 3/5 = 5x - 4/8

x + x - 5x = -4/8 - 6/4 + 3/5

-3x = -2/4 - 6/4 + 3/5

-3x = -8/4 + 3/5

-3x = -2 + 3/5

-3x = -10/5 + 3/5

-3x = -7/5

x = (-7/5)/-3

x = -7/(5*-3)

x = -7/-15

x = 7/15

Check:

7/15 + 6/4 + 7/15 - 3/5 = 5(7/15) - 4/8

14/15  + 6/4  - 3/5 = 35/15 - 2/4

56/60 + 90/60 - 36/60 = 140/60 - 30/60

146/60 - 36/60 = 110/60

Answer:

11.18%

Step-by-step explanation:

Not completed% = 38/340*100% =  11.18%

Answer:

Length of rug = 14 ft

Width of rug = 27 ft

Step-by-step explanation:

Given:

Length of rug = 20 ft

Width of rug = 33 ft

Area she afford = 378 ft²

Find:

New sides

Computation:

Assume;

Uniform strip = x

So,

Length of rug = 20 - x ft

Width of rug = 33 - x ft

Ares = l × b

[20-x][33-x] = 378

660 - 20x - 33x + x² = 378

x² - 53x + 282

x² - 47x - 6x + 282

x(x-47) -6(x-47)

So,

x = 6 and x = 47

X = 47 not be taken, So x=6

Length of rug = 20 - 6 ft

Width of rug = 33 - 6 ft

Length of rug = 14 ft

Width of rug = 27 ft

Answer:

5 pounds above his original weight

Step-by-step explanation:

An actor gains 20 pounds for a role in a movie

He loses 15 pounds during the movie to blend with the story line of the movie

Since he gained 20 pounds and loses 15 pounds

20 pounds -15 pounds

= 5 pounds

Hence the actor is 5 pounds above his original weight
