a. total cost ($)

→ 25 = 25×2.5 = $62.5

→ 50 = 50 × 2.5 = $125

→ 75 = 75 × 2.5 = $187.5

b. 2.5n

c. $400/2.5 = 160

therefore, she can make 160 crafts by $400.

9. 7x + 12 = 18

→ 7x = 18 - 12 = 6

→ x = 6/7

therefore value of x is 6/7.

hope this answer helps you dear...take care

Which of the following shows the division problem below in synthetic division form? (6x^3+x^2-3)/(x-7)

PSYCHO15rus [73]

Answer:

Option C.

Step-by-step explanation:

If a polynomial P(x) is divided by (x-c), then we write leading coefficients inside the synthetic division line and c outside the synthetic division line.

The given division problem is

$\dfrac{6x^3+x^2-3}{x-7}$

Here,

$x-c=x-7\Rightarrow c=7$

The numerator polynomial can be written as

$P(x)=6x^3+x^2+0x-3$

So, the coefficients of numerator are 6, 1, 0, -3.

The synthetic division form for given division problem is

7 | 6 1 0 -3

Therefore, the correct option is C.
