A) 2c + 3t = 34

B) 4c + 8t = 89

Multiplying A) by -2 equals

A) -4c -6t = -68  Then we add that to B)

B) 4c + 8t = 89

2t = 21

Table rental = 10.50  

B) 4c + 8t = 89

B) 4c + 84 = 89

B) 4c = 5

chair rental = 1.25

400 reduced by twice my age is 210
Pavlova-9 [17]

Answer:

your age is 95

Step-by-step explanation:

so what minus 400 gets you 210? 190 so you took 190 away from 400 or reduced it by 190 and got 210 but you said that it was twice your age so we can do the inverse of times 2 which is divided by 2 and you would get 95.

Find the mean, median, and mode of 12, 9, 17, 15, 10
igor_vitrenko [27]

Answer:

Mean: 12.6

Median: 12

Mode: 9, 10, 12, 15, 17

Step-by-step explanation:

Mean: To find the mean you have to add up all your terms and divide your result by the number of terms you have. ((12+9+17+15+10) / 5)

Median: To find the median you have to organize your terms from least to greatest and then find your center term. (12)

Mode: Normally to find your mode would be to organize your terms from least to greatest and see which of your terms occurs the most. In this case all terms occur only once, making all your terms the mode.

What’s the remainder for this synthetic division problem?
Vesna [10]

3   |   1    5     -8     6

.    |         3    24   48

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

.    |    1    8    16    54

That is to say,

\dfrac{x^3+5x^2-8x+6}{x-3}=x^2+8x+16+\dfrac{54}{x-3}

The remainder is 54.

Another way of doing it is to apply the polynomial remainder theorem, which says the remainder upon dividing a polynomial p(x) by x-c is exactly p(c). So recognizing that the listed coefficients refer to

p(x)=x^3+5x^2-8x+6

we find

p(3)=3^3+5\cdot3^2-8\cdot3+6=54
