Answer:   " x  =  7 " .

__________________________________________

Step-by-step explanation:

__________________________________________

Given:

x + (2/7)x = 9 ;  Solve for "x" ;

Note:

Start by simplifying the "left hand side of the equation:

 [tex]x +\frac{2}{7}x =1x +\frac{2}{7}x =[/tex][tex](1\frac{2}{7}) x =\frac{(7*1)+2}{7}x = \frac{(7+2)}{7}x = \frac{9}{7}x[/tex] ;

__________________________________________

Now, rewrite the equation:

__________________________________________

   [tex]\frac{9}{7}x =9[/tex] ;    Solve for "x" ;

We now multiply each side of the equation by "7" ;

to get rid of the "denominator" within the "fraction value"

  on the "left-hand side" of the equation:

  [tex]7 *\frac{9}{7}x = 9 * 7[/tex]  ;

On the "left-hand side" of the equation:

 The "7's" cancel out to "1's" ;  since "7÷7 = 1 " ;

   And we are left with "9x" on the "left-hand side" of the equation.

On the "right-hand side" on the equation; we find that: "9 * 7 = 63 ."

   So; we can rewrite the equation:

          9x = 63 ;

To solve for "x" ; we divide each side of the equation by:  "9" ;

       to isolate "x" on one side of the equation;  

         & to solve for "x" ;

          9x / 9 = 63 / 9 ;

to get:

             x  =  7 .

Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9

d = 2.44 miles

Answer:

Rectangle = L x b = 7 x 7 = 49 inch^2

square = a^2 = 2^2=4 inch^2

Therefore the area of rectangle is more because it's area is greater than square

rectangle 's area > square's area.

Answer: 9 weeks

Step-by-step explanation:

-0.1³ + 0.6x² + 85 = 70

x ≈ 8.21998224

The answer is 9 weeks because you must round 8.22 up to 9. The reason you round up to 9 is because must include the numbers after the decimal in a week, but you cannot have 0.22 weeks, so 0.22 rounds up to 1.

Answer:Thus, a product that normally costs $20 with a 40 percent discount will cost you $12.00, and you saved $8.00. You can also calculate how much you save by simply moving the period in 40.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x . 40 = $8.00 savings.

Step-by-step explanation:

The value of 40% of $20 is $8.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

40%

To change the percentage into fractions we divide the percentage by 100.

= 40/100

= 0.4

Now,

40% of 20

= 0.4 x 20

= 8

Thus,

40% of $20 is $8.

Answer:

a and c have the same x value

Step-by-step explanation:

The line is going up, so that means there is a change in the y-values

If the line was horizontal, then there would be a change in the x-values.

Just picture it or draw it out, it would also help

a and c have the same x value

A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right.

The line is going up, so that means there is a change in the y-values

If the line was horizontal, then there would be a change in the x-values.

Answer:

see below

Step-by-step explanation:

(x) = 7 - 2x

Let t(x) =0

0 = 7-2x

Subtract 7 from each side

-7 = -2x

Divide by -2

-7/-2 =-2x/-2

7/2 =x

h(x) = 4x + 2

Replace x with x+3

h(x+3) = 4(x+3) + 2

Distribute

            = 4x+12 +2

            =4x+14

Answer:

19) [tex]x=\frac{7}{2}[/tex]

20) [tex]h(x+3)=4x+14[/tex]

Step-by-step explanation:

19)

We have the function:

[tex]t(x)=7-2x[/tex]

And we want to find x such that t(x)=0.

So, substitute 0 for t(x):

[tex]0=7-2x[/tex]

Solve for x. Subtract 7 from both sides:

[tex]-7=-2x[/tex]

Divide both sides by -2:

[tex]\frac{7}{2}=x[/tex]

Flip:

[tex]x=\frac{7}{2}[/tex]

20)

We have:

[tex]h(x)=4x+2[/tex]

To find h(x+3), substitute (x+3) for x. This yields:

[tex]h(x+3)=4(x+3)+2[/tex]

Multiply:

[tex]h(x+3)=4x+12+2[/tex]

Add:

[tex]h(x+3)=4x+14[/tex]

And we're done!
