Answer:

I thinks its b cause you have to multiply them both by 2 and add 3 and g together. hope it helps

The expression can also be 2(3 + g).

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.

Variable: A symbol without a set value is referred to as a variable.

Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.

Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

Each ride cost $2.

Each game cost $2.

Andrew went on 3 rides and played g games.

So, the ride costs = $6

and, games costs = $2g

Andrew pay in total = 6 + 2g

                                 = 2 (3 + g)

Hence, the expression can also be  2(3 + g).

a 10.21

Step-by-step explanation:

because 20 - 9.79 = 10.21

Answer:

the ans in the third one,

10.21, it shows the change

Step-by-step explanation:

20.00=c+9.79

so Pablo has 20.00 and he has to use 9.79

so if u add the change and the money he has to use, will be the money he has right now

so c = the change

so...

20.00=c+9.79

20.00-9.79=c

(so if u subtract the amount of money pablo has to pay from the money he has will be the change he will get)

10.21=c

$111.83

Step-by-step explanation:

2 pairs would be original price (35) and 2 would be half off (17.5)

35 + 35 + 17.5 + 17.5= $105

sales tax = 6.5 %

$105 * 6.5 % = 6. 825

$105 + 6.825= 111.825

Answer:

[tex]\boxed {\tt h=20\ inches}[/tex]

Step-by-step explanation:

The volume of a rectangular prism can be found using the following formula.

[tex]v=l*w*h[/tex]

We know that the volume is 12,090 cubic inches, the length is 31 inches, and the width is 19.5 inches.

[tex]v= 12,090 \ in^3\\l=31 \ in \\ w=19.5 \ in[/tex]

[tex]12,090 \ in^3= 31 \ in * 19.5 \ in * h[/tex]

Multiply 31 inches and 19.5 inches.

[tex]12,090 \ in^3= 604.5 \ in^2 * h[/tex]

We are trying to find h, therefore we must isolate it. h is being multiplied by 604.5 square inches. The inverse of multiplication is division. Divide both sides of the equation by 604.5 in²

[tex]\frac{12,090 \ in^3}{604.5 \ in^2}= \frac{604.5 \ in^2 *h}{604.5 \ in^2}[/tex]

[tex]\frac{12,090 \ in^3}{604.5 \ in^2}=h[/tex]

[tex]20 \ in =h[/tex]

[tex]\frac{8}{z^2+6z+9} +\frac{5}{z^2-9}[/tex]                 [factor denominator]

[tex]\frac{8}{(z+3)(z+3)} +\frac{5}{(z+3)(z-3)}[/tex]      [multiply first fractioni by z-3 and second by z+3]

[tex]\frac{8(z-3)}{(z+3)^2(z-3)} +\frac{5(z+3)}{(z+3)^2(z-3)}[/tex]   [distribute by FOIL]

[tex]\frac{8z-24}{(z+3)^2(z-3)} +\frac{5z+15}{(z+3)^2(z-3)}[/tex]   [add]

[tex]\frac{13x-9}{(z+3)^2(z-3)}[/tex]

This is the same as A. Therefore, A is our answer.

Answer:

Step-by-step explanation:

No, Max was wrong about his claim. Max saved 30% altogether.

Discount Offer

For the two items, the total discount that Max saved was

= (10 + 20)%

= 30%.

Averagely, if we are to determine the average discount for each of the items, we have:

= 30% ÷ 2

= 15%

So, on each item, Max saved 15% on average.

Therefore, we can conclude that Max saved 30% altogether for the two items.

Answer:

Step-by-step explanation:

The perimeter of the community garden is 130 unit.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.

Given:

Scale factor = 20

After Scale factor the Dimension are

l = 2 1/4 x 20 = 9/4 x 20

l = 45

and, w = 1 x 20 = 20

So, Perimeter of rectangular Garden = 2( l +w)

                                                         = 2 ( 45+20)

                                                         = 2 ( 65)

                                                         = 130 unit.

Hence, the Perimeter is 130 unit.

Step-by-step explanation:

point D = -6

point A = 18

distance between point D and A: 18 - (-6) = 24

midpoint distance = 24/2 = 12 units away from each point

-6 + 12 = 6

18 - 12 = 6

your midpoint is at 6

Answer:

-6 to 18 is a difference of 24. half of 24 is 12.-6 + 12 is 6 so 6 is halfway between point d and point a
