Total number of hours = 15
Let the hours spent tutoring french be x.
Therefore hours spent on scooping ice cream = (15 - x)
Amount:    Tutoring french is $15 an hour, total for x hours = 15x
For scooping ice cream  it is $10 an hour   10*(15 - x) = 150 - 10x 
To make more than $180
15x  + (150 - 10x)  > 180
15x + 150 - 10x > 180
15x - 10x > 180 - 150
5x > 30
x > 30/5

In football a field goal is worth 3 points which function rule relates the number of field goals f and the number of points p
Strike441 [17]
The answer would be B. If you want to FIND how many points a person has, you put the "p" on its own on the left of the equation, and since every field goal (f) you score is worth 3 points, just multiply "f" by 3 (3f).

For example, if someone scored 5 field goals in a game, to find how many points they totalled, just plug in the 5 for "f":

1. Get equation:

p = 3f

2. Plug in field goals for "f":

p = 3(5)

3. Solve:

p = 15

How u can convert decimal to a fraction in .23?
Vlada [557]

23

%

=

23

100

=

0.23

First we have to think that the symbol

%

=

1

100

so that

23

%

=

23

⋅

(

1

100

)

this is read twenty three percent is equal to twenty three multiplied by one divided by one hundred.

the result is the fraction

23

100

Now, to convert to decimal, simply divide 23 by 100

23

÷

10

=

2.3


and

2.3

÷

10

=

0.23

this is the same as

23

÷

100

=

0.23

Use the long division method to find the result when 2 x 3 + 7 x 2 + 14 x + 12 2x 3 +7x 2 +14x+12 is divided by 2 x + 3 2x+3
egoroff_w [7]

Answer:

2 x 3 + 7 x 2 + 14 x + 12÷ 2x+ 3 = <u> x² +2x+ 4  </u>

Step-by-step explanation:

We multiply the first term 2x of the divisor with a term ( quotient) to get the first term of the dividend. Then we multiply the same term with each term of the divisor  and subtract it from the dividend. The process continues unless we get the zero or a much smaller number than the dividend as the remainder

              <u>  x² +2x+ 4                        </u>

2x+3    ║2 x 3 + 7 x 2 + 14 x + 12

               2x³ + 3x²

     <u>            -      -       </u>

                         4x² +14x+12

                          4x²+ 6x

                    <u>     -        -      </u>

                                   8x+12

                                     8x+12      

                               <u>    -        -   </u>

                              <u>        0         </u>
