Answer:

see below

Step-by-step explanation:

Let y = the total cleaning cost

Let x = the number of roots cleaned.

Therefore, if the cost is $22 per room, y = 22x

200 = 22x

Divide both sides by 22: 9 $\frac{2}{22}$ = x

Therefore, 9 rooms can be cleaned for $200

New equation: y = 22x + 40

200 = 22x + 40

Subtract 40 from each side: 160 = 22x

Divide both sides by 22: 7 $\frac{6}{22}$ = x

Therefore, 7 rooms can be cleaned for $200 if the carpet cleaners receive a $40 tip

Can someone please help me on this one question?

Katyanochek1 [597]

A+30 = 60
a = 30

a + 2b = 60
30+2b = 60
2b = 30
b = 15

5b - 5c = 60
5(15) - 5c = 60
5c = 15
c = 3

10c + d = 60
10(3) + d = 60
30 + d = 60
d = 30

2d + 6e = 180 - 60
2(30) + 6e = 120
6e = 60
e = 10

4f + 4e = 120
4f + 4(10) = 120
4f = 80
f = 20

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

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